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
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.
