The thing is CO2 is less effected by temperature than the various propane-based "insert colour here" gas. I know that some places were worried about CO2 == twelfty brazillion fps, even when there are plenty of gnus out there (Cybergun 1911, CZ's, etc) than safely shoot sub 330fps on CO2. When I had my CO2 1911 I simply popped a fresh bulb in at the chrono and fired 3 test shots and never had an issue. Sounds like lazy marshalling and/or a lack of basic physics / engineering

Yep, the air nozzles on the Cyma AKs is the one weak point but easy and cheap to fix. One other thing to watch out for is the only chrono that matters is the one at the site you are playing at that day! My MP5 was 335-337fps on 0.20g at home but 351-352fps at the site. Bugger. Same with my GBBR but that was easier to dial down the gas valve. Snipped a coil off the spring and all good now. I figure mine is reading about 5% under (or theirs is over, but that argument won’t get you anywhere) and work from there.

Morning all, I have decided to finally tackle the huge box of gear and parts I have kicking about and thought a bring n’ buy sale would be a good way to shift it without the bore of taking photos, getting paid and posting it all. Does anyone know of any airsoft bring and buy sales in the Midlands / South West coming up? I know UCAP were looking to do one last year and Bristol Courthouse (RIP) used to put them on every month.

I am guessing there is an issue with the nozzle/cup seal/rocket valve. Borrow the nozzle from your mates bolt and see if that sorts the issue, then narrow it down to the specific part!

At it’s shortest you will get more power, by extending it you will close the gap for gas to get to the barrel and drop the power.

The output on the NPAS will depend how you have it set, from “hardly trickling out the barrel” to “section5 firearm straight to jail” 😂 1.05-1.13J on a 0.32g is pretty good. I guess there is slight joule creep with the heavier ammo, as Japanese players don’t usually use anything over 0.25g / 1J limit.

ITAS are all ex-bootnecks who play airsoft for fun and have developed their own methods to make a team more effective. Their training isn’t the cheapest but was good quality (been sent on courses of varying quality with work in the past!) and helped us work better as a unit. Youtube gives you a lot of the theory but you can’t beat someone watching you do it for the umpteenth time and give feedback! It won’t turn you into a Tier 1 door kicker, but you and your mates will be slightly better than the usual headless-chicken players out there and might spend less time walking back to respawn.

https://www.instagram.com/itas_events/Is their Insta. They hired Strikeforce for the day so I guess they could run it at other locations given enough interest. Pic from the day with Matt, Chris and myself from the DarkOak about to breach a room…again 😁

I did a training day at Strikeforce in Gloucester put on by the ITAS guys (search for them on Instagram) that covered CQB techniques specifically tailored to airsoft as direct transposition of military tactics doesn’t work. Was a busy day but ratio of 3:1 students to instructors and a final kill house scenario made it well worth the £80.

Tokyo Marui M4 and Pistol mag style ones. Still on my first one after 2+ years.

Having seen the message in classifieds I’ll take “doesn’t have a defense” and “under eighteen” for ten 😀

Only one way to find out 😁 I am putting money on +20-25fps gain with 0.30g BBs. place your bets now!

I have one in my WE G19 and it made a huge difference. Interesting to see how the std TM barrel compares (I am “downgrading” to the TM for power issues)

I would say that looks good but you could fit twice as much cover / barricades / buildings in that space! If you imagine it like a village with 2 meter wide “side streets” and maybe one 4-5m wide “main road” (with maybe a road block / check point on to break it up) When you are laying it out make sure there are some interesting angles on the roads / alley ways to keep people on their toes! Keep us informed as you build this site, looks like it could be a great semi-urban field 😀

Another snippet of info that might be useful; TM 250mm barrel > CrazyJet 250mm barrel gains you about 10-15fps. Now back to your scheduled program…

My daughter is still a bit young (7) but has shot my GBBR at targets in the back garden. She played her first LaserTag at the weekend at a friends party. She racked up 20 kills in a short game and was mainly annoyed that once the whistle sounded the rest of her team ran off like headless chickens 🤣

Some good stats there! Nice to see a scientific approach. The spread of FPS seems pretty usual, Joule output seems reasonable. Heavier ammo will give a tiny rise in Joules (due to joule creep) but in pistol length barrels it is negligible. Heavier ammo will, in theory, wear hop rubbers faster but probably not noticeable unless you fire THOUSANDS of rounds each weekend! I would be interested to see grouping sizes at 10m and 20m for the pistols, not really useful at ranges over that, that is what the rifle is for. I would decide what you want from your pistol (CQB at sub-10m? Out door secondary out to 20m? Sniper back up that has to reach to MED?) Then test at that range with different BBs and see what the grouping is.

Couple of things to check: If you have done the “green gas mod” to the mags, check that you are not over filling the mag with liquid gas. Are the mags filling correctly? I tend to fill mine in 1-2s blasts, leave it to warm up, then do again. A 8-10s fill (in stages) is plenty for 100+ shots. Is there an air lock in the mag? Give it a blast of gas while holding the release valve open, then try filling in stages again. let us know how you get on

If only because all airsofters want to Seal-Delta-commando-tier1 heroes (because they can never be the “bad guys”!)

As a GBBR user that sounds fine to me 😀 Carrying 7x 35rd mags is a killer workout! One gun that is always fun is a little AK, the Cyma CM045 (AKS-74U) is a cracking gun for the money and mags and chicom chest rig are cheap and very different to an M4. Sometimes fun to play “the bad guy” Also the v3 gear boxes are easier to work on if you want to start tinkering…

Low tech solution here - dual pane glasses from Pyramex I-force slim. Using them with FogStop they were perfect EXCEPT when you pelt it to the 4th floor of C wing and then stand in the corridor defending “Dave” (UCAP VENDATTA players will know!) when I started to fog up in the left lens only (my shooting eye and the only one I wear a contact lens in…weird!) I then took a dremel to the outer gasket frame part (having removed it from the main glasses body) and opened up the scalloped areas to allow more air flow. Still can’t fit a BB through the gap and none should be coming directly UP or DOWN anyway! Result is now that I do get a tiny strip of fog at the top of the lens, probably because the baseball cap slows the airflow but the main part of the lens stays clear. Pics below show one side modified vs the standard vent size

Any standard AEG hop rubber should do. Maple Leaf are highly rated, and I have had good results with G&G green and TM black. Have a look on AK2M4.co.uk

Yep, here it is Grab a beverage and settle down for a long read!

There was a spreadsheet produced by someone on here that allowed you to plug in the numbers and it would give an estimate of the range attainable, it even took into account hop up (Magnus effect) It might have been @Adolfhamster? Heavier BBs carry their energy further and have a more pronounced hopup effect, with no increase in drag caused by air friction. I can see what some angry airsoft techs are saying that some builds work better with, say, 0.28g vs 0.36g ammo. Best bet is to get samples of ammo and give it a test! I will try and have a search for the thread later once tea is cooked and small person put to bed

The number 2 is engraved underneath the bottom plate….watch out for the mag spring when you take it off! The Gen2 mags seem to give better gas efficiency with out the need to trim the fill tube. Nothing to do with gas retention.
