Sorry let me clarify. I'm going to buy an 04 prostock body with the back block, and vertical asa. Then I would get a trigger frame with a slide trigger and grip. I would then buy a barrel and a pump kit plus an in line regulator and a ASA. What I need to know is what internals should I buy to make this gun shoot, like pump rods, hammers, springs, kits, bolts, ect...Sorry for the bad commounication, my bad.
