Davidson Defense Engineering and Material Selection

The M.A.V. 15 uses 4150 CrMoV steel for the barrel, a chromium-molybdenum alloy that balances hardness and impact resistance. The nitride finish adds corrosion resistance and extends barrel life without adding significant weight. The billet aluminum upper receiver and handguard provide structural rigidity while keeping the platform lightweight. The 9MM nitride bolt carrier group in 8620 alloy steel handles 9x19 cycling with reliable feed and extraction.

Handguard and Accessory Mounting

The 15-inch M-LOK handguard provides multiple mounting points for tactical accessories, lights, and grips. M-LOK slots are spaced along the top, bottom, and sides, allowing customization without rail clutter. The aluminum construction maintains the upper's overall balance and doesn't add unnecessary weight.

Barrel Specifications and Twist Rate

The 1:10 twist rate stabilizes 9x19 projectiles across a wide range of bullet weights. This twist rate works with standard 115-grain, 124-grain, and heavier subsonic loads. The 16-inch barrel length provides velocity gains over shorter configurations while maintaining practical handling in close-quarters scenarios.

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