Davidson Defense Left-Handed Warden Duty 16.5-inch Mid-Gas 1:7 5.56 NATO AR-15 Freefloat KeyMod Handguard Rifle Full Build Kit

Left-Handed Warden Duty 16.5-Inch Mid-Gas 1-7 5.56 NATO AR-15 Freefloat KeyMod Handguard Rifle Full Build Kit

This is a left-handed AR-15 full build kit chambered in 5.56 NATO, centered on a 16.5-inch Satellite medium profile steel barrel with a QPQ nitride finish, a 1-7 twist rate, and a mid-length gas system. The left-handed Black Diamond Series slick side billet aluminum upper receiver anchors the front end with a left-hand ejection port and a clean slick side exterior profile that omits the forward assist from the receiver body. The mid-length stainless steel gas tube and micro low-profile steel gas block at .750 complete the gas system, and the Trinity Force ECHO 15-inch freefloat KeyMod handguard in black covers the forend. An A2 GI Birdcage flash hider at 1-2x28 closes out the muzzle end. A Davidson Defense premium left-handed M16 nitride bolt carrier group and a Mil-Spec M4 charging handle complete the upper side. The lower completion package covers a complete Mil-Spec AR-15 lower parts kit, a Mil-Spec heavy-duty 6-position buffer tube, a standard AR-15 carbine buffer at 3 oz., a standard AR-15 carbine recoil spring made in the USA, a Mil-Spec AR-15 M16 receiver end plate, and a Mil-Spec AR-15 carbine castle nut. A Special Operations AR-15 stock closes out the rear end. Lower receiver not included.

Upper Assembly

The left-handed Black Diamond Series slick side billet aluminum upper receiver anchors the front end with a left-hand ejection port and a clean slick side exterior profile that omits the forward assist from the receiver body. The 16.5-inch Satellite medium profile steel barrel brings a QPQ nitride finish and a 1-7 twist rate to the 5.56 NATO chamber, threaded at 1-2x28. The mid-length stainless steel gas tube and micro low-profile steel gas block at .750 run a mid-length gas system along the 16.5-inch barrel, a well-matched gas system length for this barrel profile and chambering. The Trinity Force ECHO 15-inch freefloat KeyMod handguard in black surrounds the barrel and gas system along the forend with KeyMod slots along the handguard body for accessory attachment across the full 15-inch length.

Bolt Carrier Group and Charging Handle

The Davidson Defense premium left-handed M16 bolt carrier group carries a nitride finish and is a purpose-built left-hand BCG designed to function with the left-handed upper receiver and eject cases from the left side of the build. The Mil-Spec M4 charging handle pairs with the BCG inside the upper receiver to complete the upper interior and finish the front end of the build.

Muzzle Device

The A2 GI Birdcage flash hider threads onto the 1-2x28 muzzle end of the barrel. The included black steel crush washer seats at the barrel shoulder and completes the muzzle hardware for this kit.

Lower Completion Components

The complete Mil-Spec AR-15 lower parts kit covers the full internal lower component group, including the fire control group, magazine catch, bolt catch, and all associated pins and springs. The Mil-Spec heavy-duty 6-position buffer tube, standard AR-15 carbine buffer at 3 oz., and standard AR-15 carbine recoil spring made in the USA form the buffer system at the rear of the lower. The Mil-Spec AR-15 M16 receiver end plate and Mil-Spec AR-15 carbine castle nut lock the buffer tube down cleanly at the rear of the lower receiver. The Special Operations AR-15 stock closes out the rear end of the build on the Mil-Spec 6-position buffer tube.
