Description
This is a flat sided (without the original reinforcement ribs) top cocking upper receiver with OEM post style front sight and your choice of 9mm or 380 barrel. It is made entirely of steel with a parkerized finish which is the traditional finish of the MAC series of guns.
The 9mm barrel is either the standard length with standard threads of 3/4-10 TPI or a stubby barrel threaded 1/2-28. The .380 barrel can either be a standard barrel threaded 5/8-11 or a stubby barrel threaded 1/2-28 TPI. They are pinned in place and made of CrMoV MIL-B-11595 material with 6 – groove, 1:10 twist and precision air gauged with inert gas vacuum stress relieved after button rifling process. The finishing is manganese phosphate, the traditional dark gray/almost black parkerizing of the MAC series guns . These were profiled on centers to provide accuracy between bore and profile which has been a problem we’ve experienced with other manufacturers’ barrels in the past.
