AR9 Pistol Kit – 10.5″ Parkerized M4 Barrel, 1:10 Twist Rate with 9.5″ MLOK Handguard

Take the guesswork out of building a high-performance AR9.
Assembling a reliable, accurate 9mm AR-15 can be tricky. The AR9 uses plenty of AR-15 parts, while also using some specific 9mm components. We’ve taken out the guesswork with this 10.5″ 9mm AR build kit: Featuring a quality 4150 CMV barrel with a 1:10 twist, it affords maximum muzzle velocity and accuracy downrange.
Inside, you’re getting the perfect setup to ensure your AR9 runs smoothly: A 9mm-specific bolt carrier group, featuring a custom billet upper with a side-charging handle, and a tuned 9mm buffer assembly that mitigates recoil and ensures reliable blowback functionality. The free-float M-LOK handguard sports front and rear Picatinny rails for installing optics and iron sights with ease.
