This DPMS replacement barrel is fully chambered and ready to install on an upper receiver. Barrel features right hand twist button rifling. Front sight post, front sight detent, detent spring, gas tube, gas tube roll pin, delta ring and weld spring are not included.
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.
