TacFire AR Pistol Build Kit 9mm Luger 4.5" Barrel Black

The TacFire AR Pistol Build Kit provides the major components needed to assemble a 9mm Luger AR-platform pistol on a customer's own stripped lower receiver. Centered around a 4.5" pistol-length barrel, this kit includes a USA-made 9mm barrel, a dedicated 9mm bolt carrier group, a USA-made Mil-Spec upper receiver, a slim free-float M-LOK handguard, and a complete lower parts kit containing all of the springs, pins, detents, and fire control components required to complete the build.

Built around the popular AR-15 platform, the kit is configured for semi-auto operation with a manual thumb safety and a right-hand layout. Once combined with a stripped AR-15 lower receiver (sold separately), the finished pistol is a compact, pistol-class 9mm build. The slim free-float M-LOK handguard provides a lightweight platform for accessories while keeping the overall assembly manageable.

• 9mm Luger 4.5" barrel (USA Made)
• Dedicated 9mm bolt carrier group
• Mil-Spec upper receiver (USA Made)
