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. It also comes to you with a lower parts kit, so all you'll need is your completed 80% lower, and either the backup sights or optic of your choice, mags and ammo of course. See below for more information.
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.
Includes one lower receiver of your choice OR no lower receiver per your choice.
