I mean...

It's not on the UKARA website. But it's well known that Frank from FS is the chair of UKARA. He doesn't have to be transparent about it. The idea is that the player asks the site for UKARA info, if it was transparent that Frank was the Chairmen, imagine the idiotic questions that would be sent to him from the average player? Search for Frank and UKARA and you'll get lots of references to him being the chair. https://arniesairsoft.co.uk/news2/85557

Heathens, the lot of you, cN you not tell that the rev has unlocked the camouflage font for the group....

You should put the price up; that is the incredibly rare left handed version.

Never seen a game, only shot in my Nans friends aunt's cousins uncles brothers back garden. Shoots like a laser will easily outrange teh bestest snipers! It's fully upgraded with every part £700 buyer pays fees, postage and for the box it comes in!

You forgot... no warranty or refund.

Why the hell does an AEG with a specifically designed longer gearbox made for more air volume for long barreled DMR builds come with a goddamn ported cylinder out of the box? Had a local tech fit a full cylinder, as well as a Perun mosfet in place of the cheap Cyma platinum one, programmed for semi-auto only and then had some electrical tape put over the full-auto sensor as well so it's doubly semi-locked! Also no pre-cocking because it's incredibly snappy on semi-auto anyway with an 11.1v lipo (ASG Infinity U-18000 high torque motor + Lonex helical gears) and I'd rather not risk extra wear on the parts and doubly not risk me accidentally leaving it cocked after a game day and killing the gearbox parts. Now comes my part. I've got a load of springs to go through as I want to find one that will do 1.14J on a .32 and another that does 1.88J on a .43. I think the current hop setup will handle it, but if not I'll need to experiment there as well. Thankfully, the hop and barrel assembly is a piece of cake to take out and it has a quick change spring system; I'd never do an AEG DMR build without a quick change spring. It's a bit of a heavy beast now with the massive 3.5-25x56mm scope (the eye relief on it is perfect for me on this) and the bipod and MAWL on the front, but I love how it has turned out!

I've invented an Al Qaida sex doll. You take it out of the box and it blows itself up!

A couple of years ago I decided to put together an airsoft squad, with a group of people I enjoyed playing with. Our goal was never to be the best, or the winners. Our goal was to have a laugh playing toy soldiers in the woods. And we're succeeding at that! It's all about silly fun, and never taking ourselves seriously. Over time our little group has grown from 5 to 17 members, all with the same "Fun first" attitude. We don't often get all of us together at the same time, but today we had a good strong group out on the field, and a lot of fun was had. Missing a few faces, including our Scottish contingent, but it was great to see so many Outcasts playing together again. Unfortunately, with over 100 players on the field, and a shortage of volunteer marshals this week, I had to work. But the Outcasts did me proud. One of our squad did, unfortunately, manage to step in front of a friendly sniper hidden in a bush, at pretty much point blank range. If it wasn't for his goggle strap it could have been really nasty. We call him Iron Skull now. @GAMBLE @Smiling-Dutchman @Honey Badger 63 What the actual fuck?

Welcome, Great first post, can we expect much of the same in the future ?🤣

It's nothing that a Dremel can't sort out. 😂

One (hopefully) neat addition to the ammo hub: 6x3 admin/utility pouch from Baribal.

Me again, but I bought something over the weekend that I wasn't expecting to because I couldn't say no to it. Guess the rest of the hi-capa build will have to be done next month instead 😂 PPS Kar98k. Came with 4 mags, 1 is leaking so I'll get that all fixed up. Coming with me to the upcoming Vietnam filmsim as the mags fit perfectly in my SKS chicom. Hop rubber is also knackered, so I've got a Flamingo bucking on the way and figured I'd stick a Maple Leaf Crazy Jet barrel in it as well while I'm in there, so those are on the way.

We did what had to be done; nobody liked doing it, but it was necessary for the sake of future generations.

But what happened to the first and second Revs?

There was me thinking all the pimped hi-capas on here were crazy money but it seems Patrol Base want a piece of the action - WTF?

First game back in about two years! Had so much fun 🤩 tried a NGRS from a guy and now I’m contemplating getting one. Maybe I need a gbbr now

Today, the armed forces of Atropia (me) went to a rather warm Airsoft Plantation in the much maligned county of Essex. As usual, the place was busy, with possibly about 200 players in attendance. The first game of the day was simple; in its first iteration the attackers (Red Team) had to transport five crates from Swaziland to the Hill Fort ("If you don't know what it is, it's a fort. On a hill") and get them inside it. They had unlimited regens on eight medics while we, as the defenders, had two lives each. We started at the back of the Mortar Pits and had a 30 second head start to get into position, which we did rather well. Most of the fighting was in the scrubland, where the maze of paths between dense bushes added to the complexity of the combat, with small opposing groups bumping into each other. I took up a position in a bush and potted three attackers before their colleagues worked out where I was and potted me. As I fell back the required 30m to regen, I noticed that the Reds were working around our right flank via the Village; I slithered into a small and heavily overgrown bunker that covers one of the exits from the Village and was surprised to find a teammate already in there. We put up a good fight, taking out a number of attackers before the defence behind us collapsed and we were shot in the back at close range. With mags reloaded, the game was turned around; I volunteered to be a medic and moved forward with one of the attacking groups, keeping about 4-5m behind them so that any casualties could quickly return to the fray. However, as a rather heavily armed medic (rifle, pistol, pyro and poison gas), I couldn't resist taking out a few targets of opportunity that presented themselves. Unfortunately, we took two minutes longer to complete the mission than the Reds. After once again reloading mags, we set off for a fallback game. As the defenders, we had one life at each of the Kill House (deploy within 30m of it), the Border and the Village. The attackers had infinite marshal regens and had to set off a siren at each location. As usual, I positioned myself on the left (known as "doing a Corbyn") along with a few other colleagues, with the aim of holding off any flanking attack from that side. The Red's main attack came through the centre and our right, but we did our bit for what felt like ages, sending lots of the enemy back to find a marshal while the sounds of conflict grew massively to our right . My highlight of this part of the game was taking out two snipers with the trusty MPiKM. When I was eventually hit, I fell back to the pill box at the Border, which is actually just three low wooden walls with large rectangular holes in them. Once the siren in the Kill House had been set off, our surviving players were given an opportunity to fall back and dig in before the Reds were unleashed. This turned out to be something akin to what U-Boat crews called the "Happy Time"; I had a superb field of fire and took out every enemy player who entered it, which they kept doing. When I was eventually taken out, I turned around to find the site owner behind me, who congratulated me on what I had been doing. I fell back to the Village, taking up a position on the left (again!) but only seeing limited action before enemy players on the other side of the Village reached the well and set off the siren. We then retired to the safe zone and took luncheon which, for me, consisted of a bottle of water. After refreshing ourselves the fallback game was reversed, albeit with a twist. We would have to set off the siren in the Village first, before moving on to the Border and finally into the woods to set off the one in the Kill House. This was a daunting prospect as taking the Village from our start point is rather tricky and assaulting the Border from the Village is a huge challenge as the large bushes and the barricades channel the attacks down two paths which are easily covered by the defenders. We slowly fought our way into the Village, with some of us flanking around to the left while the main force pinned the enemy frontally. After a very hard fight, the siren was sounded and we regrouped to attack the Border. As the site owner commented, this was one of the hardest fought actions he had seen as we gradually whittled down the enemy and pushed forward down what were perfect killing zones. However, working in small teams, we eventually cleared most of the enemy out and one of our players made it into the hut to set off the siren. After the defenders had regrouped, we moved into the woods and seemed to eliminate the defenders rather rapidly; however, it turned out that most of them had deployed very close to the Kill House, where they put up a ferocious defence until they were eventually overrun and the siren was sounded. Having reloaded again, we went out to the Mortar Pits to play an infected game; to nobody's surprise, this ended with everyone being infected. It was a great day of airsoft; the games were well designed and the site easily absorbed the large number of players present. From my perspective, the gameplay was really good, although there were the usual accusations around hit taking, which always seem more numerous after lunch at every site I have been to. I saw one possible incident of non-hit taking; the marshals reacted to it quickly and appropriately. Weapons used: CYMA MPiKM (with genuine rubbish East German furniture) Golden Eagle (JG) AMD65 ASG XP18 Commander (CO2)

So....Saturday at Apocolypse 249. Geared up, all the kids in the car and off we went. Used the wifes motor as it has more room for stuff. All set up in the safe zone and safety brief done, we head out for the first game. Noticed there was lots of rentals but they were enthusiastic and ready to go. 10 shots in, i realise the AUG is not being as awesome as normal and is double feeding, resulting in "brewers droop". walk back and swap out to the M14- its first time on the field. Damn they're heavy things, aren't they? almost need a wheel barrow to push it around on!! Blue team got destroyed on the first game, we needed coffee and bacon to regroup and get into the swing of it. Coffee and bacon consumed and we were off again, some over complicated dead, fall back, this bit is yours, this bit is theirs, blah blah KILL REDS etc. So we did. few non hit takers were introduced to the "I'm going to keep shooting until you actually call it" section of my brain, but otherwise a really good mix of maniacs and strategy users. One guy had to be escorted off site due to being a complete bell end and i genuinely hope he had a car crash on his way home after non hit taking, losing his rag and turning the M4 around to use it like a cricket bat 🤯 I dunno. i don't understand it. Went through more rounds than normal, but had a really great day, especially after the day at dogtag we had, the boys needed a good day to get their heads back into it. We did. Loved it. So other than a poorly AUG and "angry man" we had a great day. Im back at work today and i ache like a bastard but hey. it was fun.

Bendova?? Sounds like a fun girl😂😂

There's 2 typos of peoples in this world those who always noticing spelling & grammatical errands, & them who doesn't.

Forget to say, from what I've seen so far, the E&C Glock mag looks pretty good as well - another WE substitute (and feeds ok in the WE G17 gen 3 i tried it in) - and cheap at £13

But the paint job is a work of art. Takes skill to make it look that realistic.

Sellers can ask for whatever they want, I'll prob never offer their price but some like to negotiate & some don't. All depends if they really want or need to sell the item. To be fair tho... some are dreamers.

It's what it comes with. Was tempted to replace it, but it just wasn't that important to me at the time. If it was a GBBR I'd replace it in a heartbeat, but the last time I opened the pistol grip I couldn't get it closed again around the motor, so I'd rather not touch it!

Can't blame a buyer for wanting a good deal, especially when you consider they're taking all the risks, lack of warranty etc. But the dreamers wanting rrp, OR SOMETIMES MORE, for a worn gat that they'll swear has only been plinked in the garden, 🤣 yeah right. They're just greedy cnuts, or at least they would be if anyone was stupid enough to fall for their sales pitch of "honest blud, never skirmished, only plinked in back garden, but it's a laser, easily hitting 150 metres" (in his back garden🤔)

Ok, E&C Glock 34 turned up from 18airsoft at the weekend - just two weeks from placing the order (albeit it was at customs for a chunk of that time). UKARA number very nicely written in brackets after my name on the address - useful as when Royal Mail emailed me to mention that they had been advised of a parcel being posted to me, I had written evidence from that email that the UKARA number was on the package should I later have an issue with customs (I didn't - it wasn't even opened by them, and no additional charges to pay). The actual RIF is really nice. It has a slightly stronger recoil than all of my WE G17, WE G19, and Army Armament G34. Build quality is good - feels great in the hand - I'd say comparable to a WE glock, and better than the AA. Full trades on the slide and lower, including the Taran Tactical stuff too. No misfeeds on the 5 mags that I've put through it, and seems to like WE mags and AAP mags (although FPS seems a touch higher on the WE mags). Shooting at about 310 FPS on red gas at about room temperature. Body size accurate at 35m, useful range probably ends at about 40m on the stock hop with 0.2s. Only negative being that the slide has about 1mm side to side play in it when wiggled - I might be able to tighten that up somehow - but irrespective, performance seems decent.

Looks like a fairly standard receiver extension from this disassembly video: You will need a Buffer tube and sling plate. The buffer tube, obviously, to mount your stock. The sling plate to cover the big hole that the wires are sticking out of. If you can find Specna Edge denoted spares - great, should be a drop-in fit. Other brands will likely fit fine, but airsoft 'tolerances' being as they are (i.e lacking thereof), you might find yourself either filing the inside of the buffer tube if too tight on the extension anti-rotation fins, or shimming with bits of a coke can if too loose. I have experienced both.

It's a slow monday morning, so i did a bit of man maths on this - Base TM hi capa - £150 - Red Dot - £115 - Slide kit - £370 plus import and customs so lets say £450 - Grips - Found in the UK for £280 (that's a more WTF moment) - Mount - £42 plus import for lets round up to £50 External big ticket items come to £965 ish. So then you add all the little things and internals and labour and warranty and mark up, £1500 doesn't seem too bad on reflection. However, if you're in the market for a £1500 airsoft target pistol, you're an elite level shooter and know what you want and will decide your own parts list... or I have some magic beans here for sale.

Ooh let me know how this goes. I've had my eye on one for a wee while.

Amazingly the story of UKARA is truly becoming lost history because their operation is so obscure. Here is a brief mention of it being an Excel file sitting at a site called Ironfoot Airsoft that used to exist (near the GCHQ site), but the farmhouse is now demolished. So there is really no solid up-to-date information of exactly who and where and how UKARA is maintained.

Yeah, sorry about that... my bad.

Speak up buddy. The old ears aren't so good lately.🙂 Regards

Just got home from Worthing where I didn't play. Well, I did, but not as a player and I had a lot of fun. First game of the day was a marshall and two of us playing blind hillbillies defending barrels of moonshine. We had juggernaut rules, but we also had to pretend to be blind (drunk too much moonshine!), so we were patrolling around yelling things in overly exaggerated American accents and only shooting in peoples direction of they made noise. It was hilarious seeing the players trying to be as quiet as possible when there was a lot of crunchy dry leaves on the ground and sticks that go snap and then shooting purposefully just past them or over their heads. It was a proper laugh yelling about commies and the government and rich city folks and the damn squirrels stealin' my goddamn moonshine! As for the gameplay, I think it worked well but the teams weren't well balanced. We had a single blue player make it to where the objectives were and, to his credit, he held up the yellow team all by himself for a really long time. He eventually got shot in the back because yellows wrapped around, because what had happened is the yellows had captured the blue team's base and weren't allowing them to get to the bottom of the site where we were protecting the barrels. All I saw were yellow players and they eventually managed to get all 13 barrels thanks to a very sneaky kid who crept all the way up multiple times very slowly and very quietly; we were all quite impressed with how quiet he was, as obviously we could all see him, but he made no noise so we didn't shoot him. He managed to ferry most of the cans out to pass them to his team and combined with the yellows taking the blue team base, this meant that the yellows absolutely stomped. After this game they did some team balancing, moving some of the more experienced players over from yellow to blue, but I can't comment on how the rest of the games went as I headed back to the safe zone afterwards; I had a lot of guns to test and make sure were working for the Vietnam filmsim weekend next weekend at Gunman Eversley, so I wanted to make sure the m700 was set, the AKM was set and the MWS was set. Also, the local tech was bringing two of my guns he was working on, so I wanted to have a fiddle with those as he tends to leave fine tuning the hop to me (at my request though, as I'm more than happy to dial in my hop and scopes myself). But the main reason I stopped was because the new gun I was using stopped working very well. Predictably, to be fair, but I think the hop rubber just turned to dust as it stopped hopping. I bought a PPS kar98 as the guy who runs a kit shop and sells at Worthing bought a bunch of Dadio's guns (a fairly well known WW2 airsofter from a few years ago) as I think he's getting out of the hobby and this was one of them. Got the kar98 and 4 magazines for £250; 1 was leaking so I'll get that sealed up, but I reckon it's been sitting for 4 years and needs a clean and a new hop rubber, but it's set for 1J (with an adjustable bolt, so I can tweak it if needed) and I'll get it set up for .32s. That's coming to next weekend's Vietnam filmsim weekend! The other new gun I was using was the hicapa I bought last weekend at Shift Your RIFTs and with a few upgrades it was shooting phenomenally (parts I had lying about mostly, as I'll do a proper build next month) Then I collected my m14 DMR (ironically not set up as a DMR) and SR-25. First I tested the m14 and... it went back to the tech. As I went to set the hop, the motor completely died so it needs a new one. Not entirely surprised as it's a stock G&P motor and is probably about 12 years old or something, but that went back to him. The SR-25 however... that was brutal and I'm probably going to be using it a bunch in the future. He's left it to me to do a lot of testing (as I said there's no point me paying him to spend hours testing out springs and hop rubbers when I can do that myself), so I'll be finding a spring for 1.1J on .32s and a spring for 1.88J on .43s, as well as a hop setup that will lift them (might already be able to!). Didn't have my long screwdriver with me so couldn't experiment there, but with the spring currently in it it was 0.9J and hitting the 60m target accurately with every shot so I'm bloody happy about that. Really snappy too! It's been properly locked to semi-auto with a perun mosfet that has been programmed to be semi-only but then also had the full-auto sensor covered with electric tape so it's definitely locked to semi!

Pretty good day at Area-66, with some well thought out games. Helpful, friendly marshalling, but too friendly, with far too much tolerance for non-hit-takers, over-shooters, and my new bête noire, dry firing in the (not so) safe zone. Bloody airsofters, we need to ban them all to make airsoft great for airsofters. 😠

Forgot what I was gonna say. You know I've got a memory like thing that's used to get lump out of flour.

I've mulled over one of these many a time over the years, ultimately went for an ACOG for my M16 carry handle upper because that's what the Bad Company 2 M16 in BF2042 has and I love it tbh (early 2000s aesthetic). But I've never not been able to find airsoft clones of the retro Colt scope clones in stock somewhere any time I've looked, I have to say. https://www.aliexpress.com/item/1005006287579209.html?spm=a2g0o.store_pc_allItems_or_groupList.0.0.197c1c55QbPYS5&pdp_npi=4%40dis!GBP!￡41.64!￡41.64!!!51.45!51.45!%402103846917172473533577324ea631!12000036620160530!sh!UK!0! https://www.amazon.co.uk/SPINA-OPTICS-Hunting-Handle-Reticle/dp/B0C5CXQRP4 (Same product at these 2 links I'd guess) https://www.octagonairsoft.com/product-page/fcw-4x20-scope-with-colt-marking

This will be the first rifle I have bought since the Ares RDB on first release. (Maybe 2 and a half years ago?) As you may know, I went from having 36 rifles and pistols, now down to just 5 rifles and 3 pistols (With one of those rifles and one pistols for sale) in preparation for a potential move to Spain. But a chance to get a brand new one of these, which has been a rifle that eluded me for a long time. Now I finally have one! LCT AKMSU. It's teh sxe. I know it's very marmite, but I have always loved the Glory Hole Foregrip and the underfolder look. Gearbox is shimmed nicely from the factory. It's one of the more recent LCT Quick Change spring ones. Changed over motor to XT Neo High torque. Slightly louder than the stock motor but still pretty damn quiet. Front sight post was pissed so hit it with a mallet to get it more in line, hopefully it will stay in that position. Firing at 327fps at the mo. Most I will do with it now is put a steel barrel and new hop rubber in it. If I get this and my others overseas when the time comes, I might have to turn this into an angel build and just stick a tonne of unnecessary and ridiculous upgrades into it. The underfolder has the typical up and down wobble once fully unfolded. But it's not that bad at all. Cant wait to field this!

I was down the gym earlier and saw an idiot put a water bottle in the Pringles holder.

My Saturday was at Redcon-2 in Dalton Barracks near Abingdon, Oxfordshire for the "Shift Your RIFTs 2024" weekender organised by RIFT Airsoft. Getting registered and booked in was quick. Along with the wristband to distinguish between weekenders or one day only, we got a goodie bag with a site map, a raffle ticket for a RIFT game pass, flyers for some of the retailers at SYR, a little plastic wallet from Empire Airsoft (containing a company sticker and patch along with a 50-degree Flamingo VSR/GBB hop bucking) and a few other little bits. Chrono testing flowed quite quickly as at least 4 marshals were at the testing range ahead of the safety briefing and anything we planned to shoot with (including pistols) was tested and tagged if it within the limits. HPA players were apparently required to be tournament locked. Tony's brief was the stuff of legends and we all survived it! The main gameplay went quite smoothly where hit taking was pretty good though there was the odd squabble and a few tellings off by other players that "hit players don't talk" (other than saying they're hit) but it didn't escalate. We were allowed to call for a medic's help (any player able to put a coiled wristband over the hit player's wrist without being hit) if we were hit by a BB (melee and grenade kills didn't count). The medic was only practical for players in groups and certainly not for lone wolves. The morning session did become somewhat unbalanced as a lot of Red Team returned to the safe zone well ahead of the lunch break so Blue Team did become more dominant, especially as we pinned Red Team to their spawn location. In the interest of sportsmanship, Blue Team voluntarily fell back to allow Red Team to spread out and return something of a fight. In the afternoon gameplay, there was some team rebalancing as some players had taken a break. During the morning and afternoon sessions, convoys of military vehicles, including Sntach Land Rovers, were at our disposal to board and be driven along predetermined routes and dropped off at certain points. There were a few additional activities players could take part in off the main gameplay field including a 4v4 Arena Tournament, a Bunker Bash, a Revolver Duel (lots of laughs) and a Target Maze time trial. Food and drink options were plentiful. Breakfast rolls were available prior to the morning brief, hot savoury pastries, chocolate bars, water and canned drinks were available all day. Lunch on Saturday had hot dogs and chilli dogs (the chilli was homemade). In the evening, the MoD fired up the BBQ and served burgers and RIFT opened up its bar for beer and cider to round off the evening. Queues did get long during the lunch break but they moved quickly thanks to the catering staff being so efficient. RIFT's White Sphere Tactical partner store for RIF and accessory sales ran raffles across the weekend. Saturday had an 11-prize raffle with items including a Nuprol (I can't remember if it was large or XL) hard carry case, a tactical vest kit, several RIFs, a lifetime RIFT Airsoft membership. Sunday had 10 prizes available for the raffle. The weekend raffle was for a Tokyo Marui NGRS Mk 18. In addition to the raffles, there were promotional items for the event including t-shirts and morale patches. White Sphere Tactical also offered a 20% discount on Deadly Customs and Viper Tactical gear and they had the TM MP7 GBB available in limited quantities at £250 - they sold out by lunchtime. Charity donation buckets were around the shop and in RIFT's own shop (selling ammo, gas, merchandise and memberships) raising money for blood donor services. As the name of the event suggests, players could sell their unwanted RIFs, parts, gear, etc so there were a few bargains to be had. In addition to the private sellers, there were retailers selling RIFs, parts and gear, including the likes of BZ Tactical, Only Airsoft/Combat UK, Empire Airsoft (joined by Big Steve's Builds), Two Four Delta Surplus, Second Summit Surplus, Finch Embroidery, Viper Tactical and a few more. In terms of staffing and facilities, the event was well covered. As there were a lot more people attending than normal days/weekends at Redcon-2, everything had to be scaled up. There were 30 or so marshals to cover 500+ people on the gaming area, safe zone and camping area. As the event was open to the public for the boot sales, there was security patrolling the site also. I had no cause to fault any of the staff so if you got any grief from them, I would assume you had behaved like genitals and probably for the second time. There was no drinking water for the campsite - you'd have to either bring along your own or buy it at the site. For showers or bathrooms, none were available so it's up to your imagination for cleaning yourself if you stayed overnight. There were lots of portaloos about the site, some of which were turned around intentionally on Saturday so there would be "fresh" ones for those attending on Sunday. Inside White Sphere's shop leads to plumbed toilets but it was reserved for ladies only for this weekend. I had a brilliant time again at SYR and will certainly go back next year. The atmosphere was really good, helped by either catching up with friends to play alongside or making new acquaintances as we were all there for the same reason.

9 months later got around to finishing up the BRT CAR15 SD, however been so long I forgot my plan to short stroke this one so need to pull the box out again😂

Should know that it's 1.3J, for an auto-capable gun designed to discharge only small plastic missiles to not be considered a firearm. And it's the capability to discharge a missile of any kind. There's nothing compelling the State to drop in 0.2g BBs, or plastic. The intent of the legislation is to limit lethality: they could drop in steel. Not that I think that they will, but we should strive to be technically correct. Try not to sweat it, @Airsoft84, you're a long way from any sort of trouble. However, if you do get another call or an invitation to attend an interview, I would suggest asking to speak to the duty solicitor at the station before making any more admissions. You could also approach UKAPU for advice.

... they are probably chronoing it. I think they will see that it is just a genuine mistake and might try their best to let it slide, e.g. dial up the hop up and using different weight or brand BBs so it passes chrono without them having to do any more paperwork. I am just guessing of course.
