5.56 AR 15 Rifle Kit – 16″ Parkerized Barrel, 1:8 Twist Rate with 15″ M-Lok Handguard

Description

Time to get more “hands on” with your black rifles. What do we mean by more “hands on?” We mean it’s time for you to take more control over your AR-15 experience. Don’t just go buy another AR from your local gun shop; build it your damn self with this kit.
This build kit gets you an AR chambered in 5.56mm NATO (yup, the same caliber as the military’s M4 rifles) with a 15-inch M-LOK free-floating handguard for you to mount your vertical grip, tac light, or whatever else onto it. Just get a lower, some mags and ammo, and add the backup sights or optic of your choice, and you’re good to go.
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.
