Barrel and Gas System Design

The 14.5-inch 4150 CrMoV barrel pairs with a carbine length gas system to deliver consistent cycling and controllable recoil impulse. Government profile construction provides durability for extended shooting sessions, and the 1:7 twist rate stabilizes a wide range of 5.56 NATO ammunition weights. Phosphate finish protects against corrosion during regular use and storage.

Upper Receiver and Handguard Integration

The 7075-T6 upper receiver is machined for precision fit and anodized for durability. The 12-inch freefloat M-LOK handguard allows you to add accessories exactly where you need them without affecting barrel harmonics. Freefloat design means the handguard doesn't contact the barrel, supporting shot-to-shot consistency.

Bolt Carrier Group and Reliability

The 9310 alloy steel bolt carrier is full auto compatible and finished in nitride for smooth operation and corrosion resistance. Mil-spec dimensions ensure compatibility with standard AR-15 uppers and lowers. The heavy duty pistol buffer tube and 3 oz buffer weight are tuned for this carbine gas configuration.

Magpul BTR Brace and Ergonomics

The Magpul BTR pistol brace combines high-strength polymer construction with metal reinforcement for durability and comfort. The brace design allows stable support while maintaining the compact profile that makes pistol platforms popular for close quarters work and storage in tight spaces.

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