This FightLite MCR barrel assembly is a complete 12.5" replacement for MCR rifles and upper receivers, and it also fits Shrike 5.56 rifles and uppers. It is chambered in 5.56 NATO with a 1:7 twist and a heavy profile built for sustained fire use. The barrel extension arrives with headspace already fixed, so it drops straight into the MCR quick change system. A mid-length gas system with a 4-position adjustable regulator and piston lets you adjust the gas setting on the rifle.

Included with the barrel are the gas block assembly, piston, flash hider and dovetail cover, so it comes as a complete assembly. The muzzle is threaded 1/2-28, which lets you swap in a different muzzle device if you prefer. The finish is black manganese phosphate over steel. The assembly is made in USA.
