The 11-inch barrel length delivers excellent ballistic performance with 9mm ammunition while maintaining a compact overall footprint. This configuration provides effective range capabilities in a maneuverable package ideal for close-quarters applications and pistol-caliber competition.
The KAK Industry 9mm Mini Compensator with 1/2x36 thread pitch effectively reduces muzzle rise and felt recoil, allowing faster target transitions and follow-up shots. This compact compensator maintains the build's overall short length while delivering tangible recoil management benefits specific to 9mm pressures.
The lightweight 6061-T6 aluminum M-Lok handguard freefloats the barrel for improved accuracy while providing ample mounting options for lights, grips, and laser modules. This construction keeps weight minimal for enhanced handling in compact pistol configurations.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. SBR Ready configuration ships without a brace.
