I want to upgrade the internals but not sure what to do or get anyone have any suggestions. Shoots about 320's to 330's FPS. CA Silencer, BSA RedDot, G&G Foregrip with 2 rails.
New to Airsoft, This is my M15A4 with foregrip and silencer

I recently upgraded my CA M15A4 with a PPA100 spring. AEX charged $45 for the spring and labor. The gun now shoots 390FPS. Get a 9.6V mini battery for the foregrip. The gears and piston should be the first parts to fail after some time.

The spring will make that much of a difference?

The PPA100 spring is fine. I asked AEX to get my gun to 400FPS. The PPA100 got me the closest without going over. The PPA springs are fine, so are the Guarder springs. For CA guns, the FPS is slightly different for each gun. AEX said that the FPS upgrades for TM's are more predictable and accurate.

Are you sure it is PPA100 and not PPA110? 400 fps with .2g seems kinda high for a PPA100 spring.

does seem high, I had a PPA110 in my CA M15 and it was shooting about 400fps.

PPA100s hit a bit harder than regular 100s...my Thompson hit high 380s shooting .20s.
