9mm AR 15 Rifle Kit - 16" Parkerized M4 Barrel, 1:10 Twist Rate with 15" M-Lok Handguard

For those who need 9mm to act like a NATO rifle round.

This 9mm AR rifle kit with its 16" barrel is just what you need if you're looking for blowback rifle cycling action combined with the laser precision of the AR platform. It comes fitted with a mil-spec 4150 chrome moly vanadium barrel, forged to achieve MOA accuracy or better within 150 meters. It sports the time-proven 1:10 twist rate necessary for getting the ballistics right for just about any 9mm loads, with a free-float M-Lok handguard that gives you all the space you need for mounted add-ons like pistol grips, tac lights, or whatever else.

All components included with this 9mm kit are of high quality and completely 9mm compatible: A forged (7075-T6) "slick-side" upper loses the forward assist (it's 9mm blowback; you don't need one) and a dust cover to give off that cleaner look. A buffer weighted for 9mm rests inside the forged six-position buffer tube, fixed with an M4 buttstock. Everything's finished off with an industry-leading Type III Hardcoat finish and a QPQ Nitride treatment for the barrel, squeezing out every possible bit of accuracy compared to a chromed-lined and phosphated barrel.

What’s Included

This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with buttstock.
