Compact 9MM AR Pistol Configuration

The Black Dagger is purpose-built for shooters who want a short-barreled 9MM platform without the complexity of NFA paperwork. The 7.5-inch barrel paired with the billet upper receiver creates a highly maneuverable pistol that maintains reliability in confined spaces. The Vertex upper receiver is machined from 6061-T6 billet aluminum and finished with Type III hard coat anodizing for durability. The Akali barrel is forged from 4150 CrMoV steel with a phosphate finish, giving it excellent corrosion resistance and a proven track record in duty applications.

SBA3 Brace and Ergonomics

The SB Tactical SBA3 is an adjustable stabilizing brace that provides a solid cheek weld and control platform without adding unnecessary bulk. The brace is constructed from polymer and features adjustment options to fit various shooter preferences and hand sizes. This configuration allows for precise control during rapid fire and tactical transitions while maintaining the compact profile that makes this platform valuable for close-quarters applications.

9MM Compatibility and Magazine Options

The nitride bolt carrier group is specifically engineered for 9MM and features an external extractor design that accepts both Glock and Colt pattern magazines. This dual-compatibility feature gives you flexibility in ammunition sourcing and magazine availability. The 1/2-36 thread pitch on the barrel matches the included flash hider and allows for future suppressor compatibility if you choose to upgrade. The 1:10 twist rate is optimized for standard 9MM ammunition weights and provides reliable cycling across a wide range of loads.

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