For those who need 9mm to act like a NATO rifle round.
This 16"-barreled 9mm AR upper assembly is the tack-driver you need if you're looking for blowback functionality with the laser precision of the AR platform. It comes fitted with a mil-spec 4150 CMV barrel, forged to afford MOA accuracy or better within 150 meters. It sports the gold standard 1:10 twist rate necessary for accurizing just about any 9mm loads, with a free-float M-Lok handguard that provides all the space you need for accessories, a pistol grip, or a bipod.

The forged (7075-T6) "slick-side" upper ditches the forward assist (blowback cartridges don't require one) and that flappy lil' dust cover for a cleaner look. Everything's finished off with an industry-leading Type III Hardcoat finish and a QPQ Nitride treatment for the barrel, squeezing out that last bit of accuracy compared to a chromed/phosphated barrel.
