hey guys, i recently got rid of my cronus tactical and got a bravo one in its place but the hammer and valve are rusty as hell. can any of you suggest any good replacement parts for them? i was looking at zero kick hammers and ACT set ups but with being new to the sport i'm still unsure what parts i can use (whether my marker supports ACT etc)
Also if anyone has installed an E-grip onto theirs......is it worth it? i plan to go mag fed so i dont know if i'd use the full auto anyway :P

thanks guys
