5.56 AR 15 Pistol Kit – 10.5″ Parkerized Barrel, 1:7 Twist Rate with 10″ M-Lok Handguard

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 clearing rooms in no time and having your home on lockdown.

We’ve taken a comfortably short 10.5-inch parkerized barrel made of chrome moly 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 shooter that’s fun at the range.
