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.
