HMI-R lipless xpt retaliator

thingiverse

Lipless xpt bolt sled conversion kit for recon/retaliator. The conversion kit increases the plunger tube size to 85ccs and removes the slack on the prime that is commonly found in retaliators. The internals are designed to work with a 1.5in metal sink tailpiece. Included in the files is either a pusher breech or a breech designed for housing a brass sleeper breech. The catch is also a design change from the worker upgraded catches to have the catch spring centered, a rounded catch surface to allow more surface area so you can run a lighter catch spring, lastly an extended trigger ramp to make it more responsive.
