i am purchasing an airsoft rifle which is the G&G CM16 (non-blowback) M4A1 and it is a truley amazing gun...but my sites FPS limit is 328 +/-5%, 360 max or something like that, so i need a different spring as the standard spring gets 290-370 fps apparantly, so... what is the best to get enough fps to be over 295fps and under 360 fps ??

thanks, Zakaria

It's ares, it'll be ok...

it depends on what brand of spring you get.
hang on a minute I have a graph somewhere.......
handy chart

Send the doctors home, I'll be doing the operating around here.

i dont know the make ...it is on Zero one Shop and it just says
"Upgrade Option:
Factory Standard (260-370 fps)
M90 Spring & Bushings Fitted (+ 35.00)
M100 Spring & Bushings Fitted (+ 35.00)"

but thanks for the chart :)


EDIT
im guessing M90 springs usually get around 300-330fps? and M100's get around 330-370?
so would i be better off getting an M100 spring?

EDIT2 i meant " would i be better off with a M90 spring?" lol sorry

It's ares, it'll be ok...

site limit is 328fps (or 1 joule)
M90's give 290-330 ish
that is the ideal FPS for you.

Don't stretch what you are allowed with the tolerance, always aim to be BELOW the site limit, and by at least 5 FPS. (chronoing at around 320fps is perfect for ALL assault weapons)

remember, FPS means NOTHING in-game, you really just want range and most people confuse the two.
I could get a stock JG shooting further by not touching the spring, just adding a better hop up unit and better air seals than some stock 500FPS sniper rifles.

yeah i understand how people get confused my friend really wants a pistol ...lets just say he is buying my cheap springer for 10, he said, "yeah, i know it is not too good but all i need it to do is tap them on their body," so i thought ... your still not gonna survive but he is buying a 20 holster for it aswell! but i dont want to be banned from the site, a guy i know got banned from the site due to his SRC M4A1 being 1FPS over the limit!!!!! so i want to watch it.

but thanks for all your time and help Rock-climby-Dave! *updating basket*

Its a hard question to answer lots depends also ont he compression in the hear box itself, I have a KWA SR10 I ahve been changing springs for ages looking for the best FPS get me near 350FPS

Its been driving me insane the best spring I have used so far is the Systema M100 (though the last time I had it fitted I did not put enough BB's through the gun to let it bed in, though I have refitted it and its sitting at 338 to 345 need to put atleast 5,000 BB's through it first to get it to bed in

All guns have a different tolerance,

Have a look at the Systema, Lylax, Guarder springs

I was using this guide as a reference but it does not really help that much

We do have a sticky topic in the guides section:

http://www.airsoft-f...?showtopic=2502

This is only worked out mathematically though, not tests as above. As stated in the topic it is a rough guide.
