This is a complete barrel assembly chambered in 5.56 NATO, built for MCR rifles and for both MCR and Raptor upper receiver assemblies. The barrel is 16.25" long and nitrided, with a 1:7 right-hand twist and a heavy profile made for sustained fire use. A mid-length gas system with a piston and a 4 position adjustable regulator lets you change the gas setting to suit your setup. It also fits Shrike 5.56 rifles and uppers, in addition to the MCR and Raptor platforms.

The assembly comes with a barrel extension with fixed headspace and a gas block assembly, so the main gas-system parts arrive together. A flash hider is included, and the 1/2-28 thread pitch tells you which muzzle devices will thread on. The QC carry handle assembly gives you a handle to carry the rifle by. A barrel dovetail cover is in the box too, and the whole assembly is made in the USA.
