Technical Information

Notes:
  • Barrel extension, installed
  • Button Rifled
  • Right Hand Twist
  • Front sight is the tower only, does not include post, detent or spring

    Barrel Gunsmithing Notes:
  • Recommended barrel nut torque value: 30 ft-lbs minimum, then continue to torque in order to align the next available gas tube notch in barrel nut, but not to exceed 80 ft-lbs
  • It is also recommended to apply a small amount of moly (molybdenum disulfide) grease to the receiver threads. Moly grease is available at most automotive parts stores
  • The use of an AR action block, receiver block insert, gas tube alignment tool and quality armorer's wrench is recommended for barrel installation
  • Due to the manufacturing process, small burrs may occur inside the bore near the gas port. It may be necessary to run a cleaning patch through the bore to clear this burr before use.
