Speedbird_666

In a nutshell - here are the arguments presented (heavily paraphrased): - not made in the UK - Wrong Calibre (they want 6.5 or 6.8mm) - Not modular enough to re-equip with .300 BLK BCGs and Barrels easily for sneaky sneaky work. - Direct Impingment = Runs too hot for sustained fire (apparently) - Direct Impingment = no good for general infantry as they cannot clean it properly (apparently) - Direct Impingment = crap suppressed performance with excessive gas to user's face (apparently) - Should be a piston gun. Doesn't matter that the US Military have been running these type of guns for that last 50+ years, and will be for decades to come - even with the M7 rollout (if that actually happens).

That's...err...wow....going to be quite a build. I shudder to think of the cost, but it will be most impressive when put together. I'm resisting anything MWS because I can see it'll a big hole that I'll end up pouring my money into... [*cue internal argument to try and justify it to my missus*] - nope - I need to stay well away from joining the TM master race.

Nope. The entire switch setup has actually been patented by ICS. I actually have one on my desk in front of me - belongs to my neighbour after I replaced the one in his L85. I still scratch my head at the mechanics of it - some very clever people at ICS - just wish they used materials other than ABS and potmetal to put it together. If you need me to pull it apart for pictures, let me know.

They are pretty reasonably priced in the UK (£150). Weirdly this vendor say no Mosfet, but everywhere else says that they do have one fitted. https://www.patrolbase.co.uk/arcturus-at-st01-lwt-ar-15-cqb-sport?pv=21428 I've seen a couple of reviews on it now - my stance on the microswitch trigger is softening...slightly

I would be very wary of second hand guns if you are a beginner. Buy a duff gun - you won't be able to fix it - so off to a 'tech' it goes for a £30-50 hourly charge + parts. It could end up costing more than new. Whilst warranties are not worth much to an experienced player, they can be a bit of a safety net for the new player (assuming they don't rip the thing open for 'upgrades').

When I win the lottery and setup my own site* - there will be a ROF cap of around 16-18RPS. Gun over that? You'll be shooting semi-only for the day. *Assuming I have enough time/braincells after the hookers and cocaine.

Sadly this. I would go as far as saying that buying too cheap now (i.e. charger) will cost you more money in the long run. There are some very decent guns around the £150 price mark, but it's the extras that add up quickly to the cost.

M904E owner here - the G model has a standard buffer tube so you can change the stock, E model has the proprietary PDW stock that kind of resembles the Q Honey Badger. That's the only difference, so pick whichever you prefer the look of. Not a huge fan of the E model stock myself - but it works ok and extensions are available to increase battery space . Specna CORE is fine, but Double Eagles are better in terms of features (e.g. Falcon ETU) but slightly more expensive. Specna FLEX is better value for money over the CORE series if budget is an issue.

Well - that's a shit design. I would 3D print a plug to mount inside the rail. I would love to know more about the rest of the gun and how it performs @Cr0-Magnon

The Specna Flex shares the same gearbox as the CORE line - which in turn is a very generic bog standard V2 gearbox. Perun have their own instruction video to cover it. Bear in mind you might end up paying a tech more than the gun's worth to have the work done (ETU + hourly tech charge). If you are desperate for and ETU-equipped gun, and cannot do the work yourself, you might be better off selling the Flex and buying a gun with an ETU equipped out of the box - like a Double Eagle M9xx series.

Yeh my local GW does it. Ended up with quite a few free Space Marines taking my son there over the last year or so. Brilliant strategy really - they must only cost a few pence (if that) but it certainly helps with bringing in new customers - I've spent a fair bit there now because of it.

Short barrel AEGs are notoriously noisy things and a silent piston head will do approximately zero to ameliorate that. The noise you hear is excess air from an over-volumised cylinder compared to barrel length. You could replace the cylinder, but that may restrict your options should you wish to lengthen the barrel later. @ak2m4 Sells a ZCI 1/2 Cylinder that would be suitable for your stock inner barrel length. G&G stock piston heads are ok, not necessary the hardest-wearing plastic, but it it isn't broken there's not much point in replacing it.

There's a couple archery clubs around my parts (southern England) - It's reasonably popular. More gun clubs though - Airgun shooting is very popular - many clubs are full (with waiting lists to join) - mainly down to the fact that Sub 12ft/lb Airgun rifle ownership does not require a license (6ft/lbs for pistols) south of the Scottish border. Both clubs I belong to have a good number of junior shooters too.

Welcome to the forums. You don't state where you are based - so I'll assume UK. My notes: - Don't replace the barrel yet (I don't think the AEP barrel will work anyway). The TopTech stock barrel is decent enough - just give it a good clean for now. - Start with replacing the hop rubber and nub and see how it performs: https://www.ak2m4.co.uk/internal-parts/hop-up-buckings-nubs/maple-leaf-macaron-60-nub - This gun uses the older-style G&G hop unit, which isn't bad, just a bit outdated - maybe later replace it later with a ZCI Plastic rotary unit (when back in stock): https://www.ak2m4.co.uk/internal-parts/hop-up-chambers/zci-rotary-hopup-chamber-plastic-m4 - Chrongraph your gun before and after any upgrades. There's a good chance that as-is, your gun will struggle to hit 300fps (TopTechs of this era were 1j/328fps from the factory to UK shores but often were below that). - Consider a longer inner barrel/mock suppressor if you need to get the FPS up - the very short barrel means that the gun is over-volumised (hence the noise) which means a good deal of air is wasted in the firing cycle. A longer barrel will make use of that extra air and provide additional FPS as a result. None of the above involves opening the gearbox. If the gun shoots well enough after the above, then happy days. Given that the gun hasn't been used in some time, here are some other things to consider next if you are having any performance problems: - If you are confident on opening the gearbox - clean and relube, particularly the compression parts (Piston, Piston Head, Cylinder and Cylinder head etc.) - Replace the piston and cylinder head O-rings - Important Inspect the gearbox casing for any cracks around the front/Blowback port - Toptechs are notorious for this (example below). You can do this to some extent without taking the gearbox out of the lower receiver: - Inspect the gears for any wear/damage - Inspect the piston rack for any damage to the teeth (G&G Pistons aren't great) I'm sure others will chime in shortly, but my advice is to keep it simple (and cheap) to start with.

Yeh - but the Specna Flex does not have the requisite trigger unit or wiring to plug in a Perun ETU++. G&G ETU Trigger unit: Specna Flex Trigger Switch: So if you want the function of the ETU++, you will need to open the gearbox and replace the traditional trigger shuttle assembly - and if you are doing that you may as well skip straight to the Perun Hybrid as is a fully optical/magnet based system that doesn't wear out like the switches on the G&G trigger units can. If you are only interested in semi-locking the gun, you can do that mechanically via modification to the selector plate, or adding a set screw to the side of the reciever to prevent the selector switch rotation to the full-auto position. But if the gun locks up for any reason - it's unlikely to be unlocked in-game without being able to select full-auto.

So - I occasionaly wear one of these olive Webtex shemaghs around my neck (some events even mandate them for opfor kit). For my own edification - are we saying that some people find it offensive to wear something like this?

Thanks. I'm not planning anything like RIFs etc - just some RS bolt-on accessories that are trickier to source in the UK. And the 5.11 HQ & clearance outlet is also within reasonable travel distance, but I can wear a new set of Taclite pants on the plane home...🙂

I have 4 days to kill in San Francisco in September. Not a holiday, but I have to go for...reasons. Was planning to visit some stores in the wider bay area (SF has nothing itself) with the hope of picking up some RS plastic bits (i.e. Magpul or similar Stock(s) and AR pistol/vertical grips) and maybe some playing gear. Anybody bought anything like that back in the hold luggage? Any problems with airpost security/customs? Ta

Don't forget Ambush at Botley - not a bad site - they just need to work on the fields a little as it was primarily a Paintball site - but they've knocked that on the head in favour of Airsoft.

Perun Hybrid. If you want cheaper - you will probably be looking at a T238 off AliExpress - but reliability is somewhat questionable on those (depending on the model version). Gate Aster is a similar-priced option to the Perun, but IIRC needs an additional sticker in the gearbox shell for the trigger to work.

I think @Stevobeavo covered it in this thread: Basically, ZCI Plastic Hop Unit, ZCI Barrel, Maple Leaf Macaron and Omega style hub.

@ak2m4 It's a compatibility thing unfortunately. The PX02 is the closest metal-racked piston to the stock KWA in terms of dimensions (the GB is fractionally oversized to standard V2). It was a heartbreaking purchase - £30 for a piston delivered...😩 BUT it fits the GB perfectly - minimal lateral/vertical movement but moves freely on the rails. @zknightzero I would suggest the AOE version of the XT Piston head - the AoE needed correcting on my gun - I don't normally bother with AoE corrections in general, but this gun needed it. You might also have to shave the second to last tooth down for clearance - a couple of minutes with a file should sort it. Oh, and almost all of my guns use POM piston heads from AK2M4. Much prefer them to the aluminium types.

Hello there - welcome to the forums. 28TPA works fine in my testing - runs much cooler and draws less amps. You will get a slight full-auto ROF reduction though - which is no bad thing with the tappet timing. The extra torque shouldn't be an issue with the stock gears. I would recommend replacing the Piston and Head. The all-plastic pistons don't seem to last long - a common complaint with KWA guns. Gate Titan II - make sure you have the latest firmware as there has been issues with the way that the Titan II (but not the original Titan) 'sees' the sector gear teeth in the firing cycle with the additional sensor fitted on the board.

Yep - I had a Gamo PCP (Venari). Moved onto an HW110 and I've just bought an AirArms S500 and the tactical platform chassis (yes that's a PTS stock as a placeholder) Struggling to find anything fun or exciting in Airsoft at the moment. I'm spending most of my spare time at the moment fussing over pellet choices and my 25m Benchrest scores. If it wasn't for my boys - I would consider moving on from Airsoft altogether. As it is, my youngest is 10 - so hasn't even played yet - but is absolutely desperate to play alongside me and his older brothers. So I keep going.
