All final dimensions machined to correct mil-spec tolerances to readily accept standard AR-15 parts to help you complete an upper receiver. Laser-etched T-marks on Picatinny rail enable easy removal and re-mounting of optics, sights, and other accessories in the correct position. Interior has dry film lubrication to help reduce wear.

Inside Diameter for barrel extension slightly undersized for a tighter fit to the barrel and a more accurate rifle. Please use a heat gun or hair dryer to warm up threaded bore of receiver if barrel extension is too tight
