I just got a new ANS Chaos GX-4, and Im lovin it so far. I put air, evulutionII, and an evil pipe kit on it, and I was wonderin, is there anything else that really needs upgrading. I know the regulator is about the best you can get. This is my first cocker, so I dont know to much about internals and stuff, any recomendations on anything(bolts, pneumatics etc)? Thanks
