BCM Forged Upper Receiver Assembly, AR/M4

Built to the correct military specifications

(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.)

  • Machined for use with barrels that use an M4 barrel extension
