9mm AR 15 Rifle Kit (16" Parkerized M4 Barrel 1:10 Twist & 15" M-Lok Handguard)

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

This 16"-barreled 9mm AR rifle kit 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.

All components included with this 9mm kit are top-tier: A 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. A 9mm buffer 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 that last bit of accuracy compared to a chromed/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. It does not include the component to make a firearm: A stripped lower receiver. Pair this rifle kit with an AR-9 80% lower receiver and AR-9 jig to fabricate a receiver, sold separately.

Here's the beginner's guide to 80% lowers.

Receiver sold separately

No FFL or serialization is required to fabricate a receiver under federal law. However, state laws vary. Some states require serialization or have banned 80% lowers and gun-making kits. We encourage each and every builder to perform their own research about the state and federal laws that apply to them.
