AEG Spring for UTG M325?

Are you able to buy an AEG spring (M130) and slap into a UTG M324? If you can't, will you please show me where to get the right kind? I want to my sniper to hav somewhat 450ish fps. Also, I'd like to know how to disassemble it so I can do so... Thanks!

Joe(9BATTOUSAI) Will answer this one soon hes like the sniper rifle builder around here. But i think you can and i have no idea how to disassemble one

There are 3 versions in production. V1 & V2 have pot-metal cylinder heads that are press-fit and stamped into the cylinder. V3 comes in two flavors, aluminum head (weaker) and brass head (better option), both threaded into the cylinder.

V1 and V2 are sealed cylinders, only way to upgrade the internals would be the $40 M324 upgrade kit or more extensive ($400+) means.
If it's V3, then you can simply replace with the appropriate APS2 spring. AEG springs will not work here, they're a good bit too large in diameter.

OEM is a 11mm spring, aftermarket is a 13mm spring (referring to outer diameter here).

You'll want to keep FPS sub-500 due to the 45-degree trigger system. You can replace the stock box with an APS2 Zero Trigger (expensive but worth it) and never have to worry about sear wear again, from 0-650+fps.




Well, that's the basic idea, anyhow.
If you are interested in seriously upgrading the rifle, let me know.

Told you lol

between Joe and Cesar, you can ANY and ALL answers faster than Google.
