Fmp 3
Mike Jestis' 80% receiver for the Argentinian FMK 3 (presumably the same thing you're looking for here) can be ordered in a reduced diameter version that will not allow use of the original bolt, thereby avoiding the constructive possession risks. He also offers an original diameter version, that will accept the original bolt, for the C2 crowd.
