Product Description

The TacFire SSPK300LPK10 Pistol Build Kit is a complete AR-style pistol upper and components kit built around a .300 AAC Blackout 10.5-inch barrel with a black parkerized finish. Designed for an AR pistol platform, this kit includes a slim 7-inch M-LOK free-float handguard, a stripped billet upper receiver with M4 feed ramps, a nitride bolt carrier group (MPI tested), and essential controls like the charging handle, dust cover, and forward assist. It also includes a pistol buffer tube kit and a lower parts kit with a standard A2-style black pistol grip—making it an ideal foundation for a compact .300 Blackout pistol build (stripped lower receiver not included). Sports South Exclusive.
