Description
The BKF M4 MOD-0 Stripped Upper Receiver is a step up from our regular BKF-15 stripped uppers. The M4 MOD-0 uppers are held to tighter tolerances, Dry film lubed and tight fitting when paired with our M4 MOD-0 Lowers. Forged from 7075-T6 aluminum, this stripped upper is precision machined to mil-spec M16/M4 specifications and features M4 feedramps. Match this upper with one of our M4 MOD-0 lower receivers for a solid and dependable fit. This upper receiver has laser engraved T-Marks. (The Inside Diameter for the barrel extension is slightly undersized for a tighter fit to the barrel and will produce a more accurate rifle. Please note: you may need to use a heat gun or hair dryer to warm up threaded bore of receiver and freeze your barrel if your barrel extension is too tight.)
