Criterion Hybrid contour AR-15 barrels offer an ideal configuration for those seeking extreme accuracy without the added weight of an HBAR contour. An indent is provided opposite the gas port to enable easy installation. Also included is an M4 barrel extension. These barrels accept muzzle devices with a 1/2x28 thread. Chambers are finisshed, but barrels should be headspaced and installed by a qualified gunsmith.
These barrels are currently in service with the US Army Marksmanship Unit Action Shooting Team (1518S-HY12) and the US Marine Corps Combat Shooting Team (1516S-HY8-N).
