  • 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.

  • The use of an action block, receiver block insert, gas tube alignment tool and quality armorer's wrench is recommended for barrel installation

  • When building a complete upper, don't forget to purchase a gas tube and delta pack. You will also need a front sling swivel and swivel rivet. These parts, combined with a complete upper receiver and handguards are all you need for a complete barreled upper.
