If you're looking for a great and compact little AR pistol with a barrel that strikes a great balance of accuracy and velocity with size and weight, then look no further. This AR pistol build kit will have you clearing rooms in no time and having your home on lockdown.

We've taken a considerably compact 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 shorty of an 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 SBM4 pistol brace and complete the build, and you've got yourself a great little room sweeper that's super fun at the gun range.

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 buttstock.
