Davidson Defense Left-Handed Aegis 7.5-inch Pistol-Gas 1:7 5.56 NATO AR-15 Freefloat M-Lok Handguard Pistol Upper Build Kit

Left-Handed Aegis 7.5-Inch Pistol-Gas 1-7 5.56 NATO AR-15 Freefloat M-LOK Handguard Pistol Upper Build Kit

This is a left-handed AR-15 upper build kit chambered in 5.56 NATO, built around a Bear Creek Arsenal Irithyll 7.5-inch contour steel barrel with a manganese phosphate finish, a 1-7 twist rate, and a pistol-length gas system. The Black Diamond Series left-handed slick side billet aluminum upper receiver with a black anodized finish anchors the front end with a left-hand ejection port and a clean slick side exterior that omits the forward assist and dust cover from the receiver body. The pistol-length gas tube and micro low-profile steel gas block at .750 O.D. complete the gas system, and the 7-inch ultra-lightweight minimalist freefloat M-LOK handguard with a partial Picatinny top rail covers the compact forend. An A2 GI Birdcage flash hider at 1-2x28 closes out the muzzle end. BCG and charging handle are not included.

Upper Receiver and Barrel

The Black Diamond Series left-handed slick side billet aluminum upper receiver with a black anodized finish anchors the front end with a left-hand ejection port and a clean slick side exterior profile that omits both the forward assist and dust cover from the receiver body. The Bear Creek Arsenal Irithyll 7.5-inch contour steel barrel brings a manganese phosphate finish and a 1-7 twist rate to the 5.56 NATO chamber, threaded at 1-2x28. The pistol-length gas tube and micro low-profile steel gas block at .750 O.D. run a pistol-length gas system along the 7.5-inch barrel. The 7-inch ultra-lightweight minimalist freefloat M-LOK handguard surrounds the barrel and gas system along the compact forend with a partial Picatinny top rail running along the top of the handguard and M-LOK slots along the remaining handguard body for accessory attachment. The handguard does not include anti-rotation tabs, a design characteristic of this specific unit.

Muzzle Device

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

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