Looking for an AR pistol that's compact with a barrel that strikes a great balance of accuracy and velocity with size and weight? We've got you covered. This AR pistol build kit will have you knocking steel and making tight shot groups in short order.
We've taken a comfortably short 10.5-inch parkerized barrel made of 4150 chromoly vanadium steel and paired it with a 10-inch M-Lok handguard to bring you a compact little AR pistol that's long enough to be accurate and maintain good velocity, yet short enough not to get hung up as you move. Add in an SBA3 pistol brace and complete the build, and you've got yourself a great little room sweeper that's super fun at the gun range. Simply finish a 80% forged or billet lower receiver and assemble. Then mount your favorite backup sights or optics, grab some mags and ammo, and enjoy.
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.
