FightLite MCR 5.56 NATO 12.5" Heavy Barrel Assembly 1/2-28

This is a complete 12.5" replacement barrel assembly for FightLite MCR rifles and MCR upper receiver assemblies. It is chambered in 5.56 NATO with a heavy contour and a 1:7 twist, and the barrel extension is installed with headspace already fixed, so it goes straight into the MCR quick change system.

The assembly also carries the gas block with its 4 position regulator, the piston, a flash hider and the dovetail cover. The muzzle is threaded 1/2-28 if you want to swap in a different muzzle device. Finish is black manganese phosphate over steel.
