Could an older family member buy me an RIF?
ak2m4 and 3 others reacted to Cannonfodder for a topic
Strange. Its usually the start of school holidays when the dumb how to get a rif without a defence posts appear No. The person buying it for you must have a defence to buy rifs. If they do have a defence then they can gift someone under 18 a rif but there must be no exchange of money,goods or services. Also if you're under 18 then you don't have a defence. Yes4 points -
GBBR’s - Why a heavier weight bb?
Mr Dellski and 2 others reacted to Impulse for a topic
Essentially no, it comes down to the hop up. If you have a GBBR and an AEG, both capable of hopping .48s and both shooting at 1.1J, they will perform about the same. However, there's usually issues when it comes to voluming for AEGs which I'll go into in more detail. If you're interested in me absolutely nerding out over tiny details, continue reading. If not, you have been warned! I think it's probably because gas when it comes to propelling the BB works differently and most AEGs have voluming issues for heavy weight BBs. I've recently been properly delving into cylinder to barrel ratio stuff for my SRS, so I actually have a good understanding of it now. If I'm wrong, someone please correct me, but this is my understanding from my work on my own guns though my knowledge on AEGs is all theoretical because I just can't work on gearboxes; I've tried and failed way too many times, but I'm well-practiced on gas guns, from gas bolt actions, to GBBRs and GBBPs (and mk23s...) I'll start by citing my sources (ooooh, look at me being all professional and stuff) because we stand on the shoulders of giants http://airsofttech.dk/Guides.cshtml?Page=CylBarVolRatio_Page1 https://www.airsoftsniperforum.com/threads/cylinder-barrel-ratios-explained.14303/ Basically, a heavy BB requires more pressure to push through a barrel and takes longer to get from the start point to leaving the barrel. A .2g BB accelerates incredibly quickly through the barrel and leaves a lot quicker than a .48, assuming the same power level, so your cylinder to barrel ratio for heavy BBs tends to be higher to make sure you're pushing the BB appropriately through the barrel; you want a lot more air in the cylinder to push the BB through the barrel and also around the BB as it travels, creating a sort of air cushion around it. As an example (it's not an AEG, I'm sorry, but the mechanics are the same) I've got my SRS at about a 3.36:1 cylinder to barrel ratio for chucking .48s, so my cylinder volume is 3.36x the volume of my barrel and that seems to be about right for it (though not 100% accurate without me getting a barrel and testing it and cutting it down 10mm every time to see where it's the best. Most AEGs really struggle to volume properly which causes inconsistencies. Funnily enough, the best guns AEGs for chucking heavy BBs are things like mp5s or short m4s with shorter inner barrels. If there is too much volume it can push your shots off course after it leaves the barrel, causing inaccuracy. If there is not enough volume (a lot of AEGs using heavy BBs) it starts decelerating inside the barrel, which causes inconsistencies. With GBBs, the gas constantly expands as it pushes the BB through the barrel, so you have constant acceleration much like a real firearm; a 10.5" AR-15 firing the same 5.56 ammo as an 18" AR-15 will struggle to hit ranges that the long barreled one will hit with ease because the long barrel is giving the bullet more time to accelerate through the barrel. GBBs work in a similar way in that when the hammer strikes the magazine and releases the gas, it's constantly expanding and accelerating the BB through the barrel, so there's no issues with voluming in the same way AEGs have issues, and it compounds with heavy ammo as heavy ammo spends longer in the barrel, so it has more time to accelerate. This is why you get so much joule creep in long barreled gas guns. One of my gas m700s has a 640mm inner barrel and I find it tough getting it shooting the correct power on .48s and 144a during the summer; fortunately it's the one I don't use and is more of a collectors item However, let's assume that we have an AEG correctly volumed for heavy BBs for the sake of argument. In this instance, no, there is no inherent advantage that a GBBR will have for hopping heavy ammo. And I just saw this so you may disregard everything I typed (but I'm not deleting it because it took me time to write and I like nerding out!). I think GBB hop rubbers tend to be a bit better than AEG rubbers for hopping heavy ammo. Longer hop patches thanks to unbridged barrels certainly help getting a more even and consistent spin on heavy ammo. I put Flamingo buckings in my GBB hop rubber stuff and the patch is noticeably longer than the patch in the Maple Leaf MR rubbers I put in all my AEG rubber stuff3 points -
okay...this might be a long post! With AEGs you have a fixed cylinder volume and spring speed. This is usually matched to barrel length / diameter and BB weight you want to use (others can chime in with formulas and typical set ups) With a GBBR when the trigger is pulled the gas is vented down the barrel, and as there is a BB in the way it is at a high pressure. This keeps the rocket valve open and gas going down the barrel. Once the BB leaves the muzzle the pressure drops, the rocket valve closes and vents the gas backwards to cycle the bolt. Now BB weight influences how much energy can be imparted to it (assuming barrel, gas, temperature, etc remain the same) If someone gave you a pingpong ball and a golf ball (same diameter, ignore the dimples, you are not throwing that hard!) and asked you to throw them as far as possible, which would go further? The golf ball, being heavier, allows you to transfer more energy into it from your arm. Light BBs tend to leave the barrel too soon before maximum energy is transferred to them. So a GBBR with light ammo would be better with a much longer barrel (as it will have longer time to be accelerated, remember gas continues to vent until it exits the end of the muzzle) but would require more gas volume and still end up with less range. So a short barrel will limit time to transfer power (which is why TM use 250mm barrels to suit Japans 1J hard limit and 0.25g BBs used) Heavier BBs work better as they have the same cross section / drag as light BBs, can get more angular momentum (hop) and lose energy slower than 0.20g so go further. Time to target is negligible difference until much further out where 0.20g probably won't reach. I have 0.28g and 0.32g for my GBBR, the lighter ones to "Joule creep" the power down on hot days. This is why you chrono on the weight you use as if I used 0.20g BBs it would be 0.6J, not the 1.05J the 0.32g give me!3 points

https://www.usedairsoft.co.uk/rif-s/cyma-cm011-3-batteries-3-mags-accessories_i66388 It must be a crack-induced dream. The gun is a repainted (flaking and scraping away) two-tone and I don't see the extras being worth (used) more than the 30% depreciation from current retail, let alone the price being above retail for the base gun.1 point

This advert is COMPLETED!
- For sale
- Used
VFC HK53 Gbbr Includes 6x gas tight magazines, scope mount, Delta Point clone optic, telescopic stock, fixed stock, regular handguard and G&P flashlight handguard. Upgraded with Bowman steel barrel and CNC hop dial. The bolt has a CL adjustable valve installed and was last chrono'd at around 260 fps with a .32 bb. Gun is in mint condition, except for the tops of the magazines which all get worn down by the mag well from use. All of the magazines are gas tight and feed perfectly. The dry fire lever has been trimmed down on all of the mags as it caused issues with the mags going into "empty" mode when inserting them. The pictures show it with a T2 red dot clone fitted, but it will come with a Delta Point clone. Looking for £820 posted. I'm not looking to sell things separately so will not be doing splits.£820

GBBR’s - Why a heavier weight bb?
Enid_Puceflange reacted to SSPKali for a topic
Ahh OK, I think that might be to do with the hop chambers, barrel cut outs and general build quality. Plus pushing 0.36g BBs in an AEG needs some BIG cylinder volume and spring pressure (same for HPA set ups, higher PSI and volume) and then you are still using a hop unit designed for 0.25g BBs at 1J....1 point -
I think the point novioman is making, is that some sellers appear to ignore questions, even when renewing ads. Thing is, often when questions are asked, the information requested is usually relevant to everyone here, such as when a seller says collection only & then fails to state their location for said collection. Alternatively members, myself included, will ask a public question because of a concern of the validity of the ad, or even the seller themselves, again this is usually intended just to give all interested parties a heads up to do due diligence before agreeing a purchase.1 point

Don't cheap out on line. Airtac sells a very decent one or if you want to spend more Amped Airsoft makes quality pieces, too. Depending how much you spent at Airtac in the past you can claim certain things for 'free'. A line probably should sit around 1600-2000 psi points.1 point -

Because the 50 degree is for sub 1.49J, as UK is hard limit of 1.3J, there is no need for anything more. It's like RATech putting 70-80 degree as their default, because in taiwan, 2J is perfectly acceptable for a GBB.1 point

I thought working on your own suit is part of the fun. I got just Sniper Bolero https://www.patrolbase.co.uk/invader-gear-sniper-bolero-head-and-shoulders-ghillie-suit got some raffia and started crafting. The Invader gear bolero is very sturdy, hides the head shape nicely and it is easy to add extra stuff to it. I got some leave strips and raffia from Novritsch for that. Might not be as cheap as AliExpress but was a lot more fun then just clicking on a link.1 point

I have had more interesting usernames elsewhere. I was "Paddy" on Techbrigade, ASCUK, UKASC and Arnies, on account of having Irish Roots. As I got old and boring I just started using an abbreviated "real" name. I remember a load of guys signed up to ASCUK as a team and were "Wolf Squad Gunnner" "Wolf Squad Sniper" "Wolf Squad Leader" and then pmd the admins for name changes when the team broke up. I do remember the time HaVoC MaN got himself banned, and we weren't using validation on new users, so he immediately rejoined as Beakersuxcock...1 point

The 'What have you just bought' Thread
GothicGhost reacted to JimFromHorsham for a topic

Personally I recommend what lokkers has done there; or whatever equivalent fits in with your preferences and/or current kit. You can pick any modern placard and just get the mag inserts to fit your weapons; just be sure to get the right sized inserts (e.g. 762 generally means 762 NATO, not AK) and ensure they have the right velcro alignment/config (either hook on both sides, or hook on one side and loop on the other, depends which system you buy in to). The Spiritus Mk5 is a strong option since the modern Spiritus placards are fully loop lined and most of the inserts out there are covered in hook. There's also the Spiritus Mk4 for extra capacity, the Haley D3CR-M if you want extra pouches built in, or the F9 Ammo Hub (if I might be so bold as to self promote). Tons of other options out there which are also fully loop lined and also clones of most of them.1 point
