The PSS2 'should' fit. The PSS96 springs will definitely fit though.

Actually, disregard what I said. I don't even think they make PSS96 springs. I'm positive that a PSS2 spring will fit though. Sorry about that.

I put a PSS2 170sp in my CA M24 and it fit perfect.

Dang man, that's some high FPS results. What all did you do to lighten the piston?

 

[wesley810]

Awesome, watch you don't get it too light or it could break. Also lighter pistons tend to propel lighter bbs better than heavier. Depending on the weight, something such as Bioval .27 or .30 could work better than heavier weights such as .40

I've also heard of taking a bit off of the metal rod inside of the cylinder for one. Yeah, I would say that the .32g would be more effective than the .40g because of piston weight. I'd stick to those; are they Bioshot? If so, how do you like them? I want to order some.
