ADM Hybrid Contour AR-15 Barrel
Our 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 machined opposite the gas port to enable easy installation. Also included is an M4 barrel extension. These barrels accept muzzle devices with a 1/2×28 thread.
Chambers are finished, but barrels should be headspaced and installed by a qualified gunsmith.
