Gas Block Dimple Service: If you're planning on using a set screw style of gas block with this barrel, we highly recommend choosing the dimple service. The dimple ensures that a set screw gas block is perfectly aligned with the gas port and cannot rotate or slide out of position under extreme use.
Feed Ramp Polishing Service: Same as the Feed Ramp Polishing service we provide separately, this can help smooth out feeding and possibly prevent some feeding issues. This service is best done with the upper receiver in hand to match the feed ramps in the barrel to the upper, but can be done with just the barrel.
