Warden 14.5" 5.56 NATO AR-15 Pistol Build Kit, Keymod Handguard, 1:7, w/ SBA5 Brace

The Davidson Defense Warden with SBA5 Brace Full Build Kit gives you everything needed to complete a functional AR-15 except the lower receiver. This is a complete upper paired with all the lower components, buffer system parts, and the SB Tactical SBA5 brace. The 14.5-inch carbine-gas barrel in 5.56 NATO cycles smoothly with the included bolt carrier group and charging handle. You get a freefloat Keymod handguard for mounting accessories, a low-profile gas block, and a standard A2 flash hider. The upper receiver is 7075-T6 aluminum with M4 feed ramps, and the bolt carrier is made in the USA from 9310 alloy steel with a nitride finish.

Barrel and Gas System Design

The 14.5-inch barrel uses a carbine-length gas system, which balances velocity and handling in a compact package. The 1:7 twist rate stabilizes a wide range of 5.56 NATO loads, from lighter 55-grain rounds to heavier 77-grain ammunition. The parkerized finish provides corrosion resistance, and the government profile keeps weight down while maintaining structural integrity. The micro low-profile gas block sits low on the barrel, allowing the freefloat handguard to mount cleanly without interference.

Upper and Lower Component Integration

This kit includes the complete upper assembly, bolt carrier group, charging handle, and all lower parts needed to finish a stripped lower receiver. The 7075-T6 aluminum upper receiver with M4 feed ramps ensures reliable feeding across ammunition types. The SBA5 brace mounts to the buffer tube, giving you a stabilizing point without the added length of a fixed stock. The included buffer tube, buffer, recoil spring, end plate, and castle nut complete the receiver assembly.

Handguard and Accessory Mounting

The freefloat Keymod handguard floats above the barrel, keeping the barrel free from pressure that could affect accuracy. Keymod slots run along the handguard, letting you attach lights, grips, and other tactical accessories exactly where you want them. The black anodized finish resists wear and corrosion during regular use and cleaning.

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