6-Inch .300 Blackout Barrel with Nitride Finish

The 1-7 twist rate optimizes the .300 Blackout cartridge, stabilizing both subsonic and supersonic ammunition effectively. The 6-inch length enhances maneuverability in tight spaces while maintaining reliable performance. The nitride finish provides low-friction operation and extended barrel life. The 5/8x24 thread pitch accommodates standard .300 Blackout muzzle devices including suppressors and flash cans. The pistol-length gas system ensures reliable cycling in this compact configuration with the .750 micro low-profile gas block.

The 7-inch M-Lok freefloat handguard is made from 6061-T6 aluminum in black, allowing versatile accessory attachment while maintaining a lightweight profile. The freefloat design eliminates contact with the barrel, preserving accuracy during extended shooting sessions. The M-Lok attachment system provides modular mounting capability for lights, grips, and accessories. The handguard extends beyond the 6-inch barrel, providing forward hand placement and accessory mounting space. The upper receiver is made from 7075-T6 aluminum with M4 feed ramps and anodized finish for durability and corrosion resistance.
Nitride Bolt Carrier Group and Flash Can
The complete bolt carrier group is crafted from 9310 alloy steel with nitride finish for wear resistance and low-friction operation. This multi-caliber BCG is compatible with 5.56, .223, .300, and .350 calibers for build flexibility. The mil-spec AR-15 M4 charging handle provides reliable operation. The 5/8x24 steel flash can features anodized finish and minimizes muzzle rise while directing blast forward away from the shooter. This muzzle device aids in stealthy handling by reducing side blast common in short-barrel configurations.
