Get ready for a unique and wicked little addition to your AR collection. This AR15 pistol build kit will get you an AR pistol that performs as badass as it looks. The shortness of its overall length also makes it ideal for close encounters of the uninvited kind; it’ll make a great way for you to protect your family.
This AR pistol build kit features a pre-built upper receiver with a 7-inch chrome moly vanadium barrel coupled with a 9-inch lightweight free floating M-Lok handguard. Grab either the backup sights or optic of your choice, mags and ammo, of course.
Note: Due to ATF rule 2021R-08F, any pistol with a stabilizing brace is considered a short-barreled rifle (SBR), and is therefore considered a National Firearms Act item requiring a federal tax stamp.
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 pistol brace.
