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 Straight Profile Barrel
The straight profile barrel with nitride finish provides consistent accuracy while the nitride coating delivers a hard, corrosion-resistant surface that resists fouling and wear. The 1:10 twist rate ensures proper stabilization for common 9mm projectile weights from 115 to 147 grains.
8620 Alloy Steel Bolt Carrier
The bolt carrier crafted from 8620 alloy steel with nitride finish provides the strength and reliability needed for 9mm blowback operation. This material choice ensures consistent cycling and durability across extended shooting sessions.
Freefloat M-Lok Handguard
The 10-inch M-Lok handguard nearly extends to the muzzle, 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 for enhanced handling.
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.
