Using our receiver flats, rails and center support these receivers are bent, rails trimmed and fully heat treated, then the rails are aligned and welded. We are leaving out the center supports to work with the older drilling fixtures. All thats left to do is drill out the fire control group using our receiver blank drilling fixture and drill the trunnion holes using our trunnion hole drilling fixture.
For use with Polish Underfolder stocks. The AMMS Underfolder stock will sit at an angle using this receiver blank.
We are making these with our other flats also that should be ready in a couple of weeks.
