BCM® M4 Flat Top Upper Receiver with cosmetic blemishes. Most have scratches or scuffs.

The upper comes unassembled, but complete with BCM forward assist assembly and ejection port cover door assembly.

You must assemble it. (Assembly required) (all parts, but you will have to assemble together)

THESE ARE USED/DEMO UPPER RECEIVER ASSEMBLIES. All will have several nicks, scratches, and marks on exterior finish. NO HANDPICKING.

This receiver has the M4 feedramps machined in. This is to be used with barrels that include the M4 barrel extension.

Built to the correct Mil-Specs.
(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.)
