Davidson Defense Warden 10.5-Inch Carbine-Gas 1:7 5.56 NATO AR-15 Free-Float KeyMod Handguard Pistol Complete Upper Build
The Davidson Defense Warden Complete Upper is built around a 10.5-inch 5.56 NATO barrel machined from 4150 chrome moly vanadium steel in a government profile, with a carbine-length gas system and a Phosphate finish. It is paired with a black free-float KeyMod handguard and ships with a US-made complete bolt carrier group and a mil-spec quality M4 charging handle, so the builder receives the core components of a working upper in one package. The short barrel keeps the front end compact and quick to handle, and the 1:7 twist rate suits a wide range of bullet weights in 5.56 NATO.

Barrel and Gas System
The 10.5-inch barrel is machined from 4150 chrome moly vanadium steel in a government profile and finished in Phosphate, a matte, corrosion-resistant treatment that gives it a clean, uniform look. Its 1:7 twist rate is suited to a wide range of bullet weights in 5.56 NATO. The barrel runs a carbine-length gas system through a micro low-profile steel gas block sized for the .750-inch barrel diameter, and the low-profile block helps it sit cleanly beneath a free-float handguard. At the muzzle, 1/2x28 threads carry the included AR-15 TPI GI birdcage flash hider.
Upper Receiver and Handguard
The upper receiver is machined from 7075-T6 aluminum with M4 feed ramps and an anodized finish, giving it a hard, wear-resistant surface that holds up to regular handling. It is paired with a black KeyMod handguard machined from 6061-T6 aluminum. As a free-float design, it leaves the barrel free of handguard contact, and the KeyMod slots give the builder room to mount lights, grips, handstops, and other accessories wherever the setup calls for them.
Bolt Carrier Group and Charging Handle
The included complete bolt carrier group is made in the USA and rated for 5.56, .223, .300 Blackout, and .350 Legend, with a carrier machined from 9310 alloy steel and finished in Nitride, a surface treatment that adds hardness and corrosion resistance and helps the carrier stand up to repeated cycling. Paired with it is a mil-spec quality AR-15 M4 charging handle, completing the upper so it is ready to be matched with a compatible lower receiver.
Compatibility
This upper is built for AR-15 lower receivers chambered in 5.56 NATO. Handguard length, gas tube details, ejection port door and forward assist configuration, and crush washer inclusion were not supplied with this listing and should be confirmed before purchase.
