i would call it both cheating and irresponsible

in physics Force=Mass x Acceleration

so the force of a .25g at 350fps is still the same using .2g at 400fps

try getting lit up point blank by a 400fps gun.... just hope its not anywhere near ur face

Just use .23g bbs it puts your fps above 340 but under 350 I tried them.

The easiest way to put your gun under FPS would be a velocity reducer. Heres one on ASGI

And a upside wuold be that once you remove it, you return to your normal FPS. I have never used one but apperently they work.

The velocity limitations are in effect for safety, not so they an be bypassed at the chrono and you can use a hot gun in game play. if your gun is past cqb limits then dont play cqb.

Try this: http://www.airsoftpo...oducts_id=29489 I've never used them before, but they look like they'll do the trick.

You may want to consider switching to the M4CQB's ported cylinder.  This is what KWA did to reduce the FPS and gain some ROF.  My CQB chrono'd at 325 using .20 BBs.

yep, only it says matrix instead of pro arms lol

Get the velocity reducer, it's easier than downgrading your spring and it's much safer/honest then using heavier bbs. Just because .25s reduce FPS, doesn't mean it's safer.  Heavier bbs hit harder than lighter bbs, so in fact it's more dangerous.

They don't, It never touches the pellet in anyway, it will though reduce your range because of the less FPS.

Heres the "indepth" explaination from ASGI:
"The Velocity Reducer is an adaptor that threads onto the end of your AEG. Inside of the unit is a membrane with two slots cut into it. If you push on the membrane, the slots allow the membrane to open up. As the BB travels down the inner barrel, the membrane is closed. This causes air pressure to build up IN FRONT of the BB, which is what causes the reduction of velocity. That is how spin is maintained, and the speed is reduced without touching the BB. Once the BB gets close enough, the pressure is too great and the membrane opens, allowing the BB to travel through it. The adaptor comes with four rings. Each ring is a different width. Inside of the device are little arms that push against the membrane. Installing a thick ring keeps those arms furthest away from the membrane, meaning the membrane stays mostly closed, and the velocity is reduced the most. The thinner the rings get, the more the arms push against the membrane and open it. The more the membrane is open before the BB arrives, the less pressure is put on the front of the BB, and the faster the BB is allowed to travel."

That explains it all....
