Introducing another great addition to our line of AR pistols build kits. This particular one is chambered in 5.56mm NATO. This kit's pre-built upper assembly comes with a 10.5" nitride-coated barrel with a 1:7 twist and a 12" free floating slanted M-Lok handguard.

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.
