Compact 9mm Performance
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.
Nitride-Finished Medium Profile Barrel
The medium profile barrel with nitride finish combines manageable weight with the durability needed for extended shooting sessions. The nitride coating provides a hard, corrosion-resistant surface that resists fouling and wear while the 1:10 twist rate ensures proper stabilization for common 9mm projectile weights.
9mm Mini Compensator
The included 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.
Freefloat M-Lok Handguard
The 10-inch M-Lok handguard nearly extends to the muzzle device, maximizing usable rail space for lights, grips, and laser modules. The freefloat design eliminates barrel contact for improved accuracy while the 6061-T6 aluminum construction keeps weight minimal.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify compatibility of all components before assembly. Designed for pistol-caliber builds—confirm 9mm compatibility with your lower receiver and magazine system.
