I'm in the process of modding my Pilot ACS into a First Strike round gun. Pics will be up soon. It's going to be a single shot, bolt action type mech. Going to disable the blowback and slot the striker so working the bolt will cock the gun. Not going to put it in a rifle stock or anything. I want to nice short trigger pull so I modded my E-frame to a single trigger. More than likely going to go with a CP Tactical barrel so I can put a sick tip on it. Just wish Kingman didn't use cheap *** metal for their screws, and frames.
