Compact 300 BLK Configuration

The 8.5 inch barrel length provides a balance of velocity retention and overall system length in 300 BLK. The pistol gas system is matched to this barrel length for reliable cycling with both supersonic and subsonic ammunition.

Freefloat M-Lok Handguard

The 7 inch handguard uses M-Lok attachment points along its length. This allows modular placement of accessories without adding bulk. The freefloat design isolates the barrel from handguard contact.

Durable Upper Receiver

The 7075-T6 forged aluminum upper receiver features an anodized finish for corrosion resistance. The upper is compatible with mil-spec AR-15 lower receivers and standard fire control groups.

Threaded Barrel with Flash Hider

The barrel features 5/8x24 threads, a standard thread pitch for 300 BLK muzzle devices. The included GI birdcage flash hider can be replaced with other compatible devices including suppressors.

BCG and charging handle are not included. Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
