I have a completely stock CA M15A4. I just wanted to improve the FPS and range of the gun and I already have a TB barrel. Any suggestions would be greatly appreciated. Thanks.
Throw in a slightly stronger spring. Bore-up kits are nice too. It all depends on how much you want to spend.
That and how much fps you want boosted lol
For accuracy and range, pick up a Systema bucking and a SCS. SCS (Shredder's Concave Spacer) is like a perfected H nub and works much much better than the E1 (element) H nub set I have. It not only gives tighter groupings and more range, but it also boosts the fps a bit.
They can be purchased here, just call to order. They are like 8 bucks shipped

I believe CAs have 7mm solid bushings? I would throw in some 7mm bearings (not needed), a ball bearing spring guide, a Guarder SP110 (gives about 380 fps, perfect for AZs limits), a Systema bucking, and a SCS. You will be amazed how well the SCS works. (I suggest Systema because the creator of the SCS says it works best with Systema/Guarder buckings)
hope this helps.
