The AUG HBAR barrel returns to the USA. Originally designed to be paired with the 42 round AUG waffle magazine, the HBAR allows for extended and controllable strings of fire. The HBAR’s classic profile brings both form and function, pushing a 55gr 5.56 round at upwards of 3280 fps (1000m/s). The increased diameter of the barrel was designed for extended fully-automatic fire and heat control. All AUG HBAR barrels ship with the classic, aggressive vertical recoil mitigation muzzle device and adjustable-cant bipod. Like all AUG barrels currently being produced, these barrels are cold-hammer forged in Steyr, Austria before being machined and assembled in the USA.
