The Aegis 16-inch Carbine-Gas AR-15 Complete Upper Build from Davidson Defense is engineered for precision and reliability. Chambered in 5.56 NATO, it features a 16-inch barrel made from 4150 CrMoV steel with a phosphate finish and an M4 profile. The barrel has a 1:7 twist rate, optimized for stabilizing heavier projectiles. It employs a carbine-length gas system utilizing a micro low-profile gas block for efficient gas flow.
The upper receiver is crafted from durable 7075 T6 aluminum with an anodized finish, while the freefloat handguard is constructed from lightweight 6061-T6 aluminum, providing M-Lok compatibility for accessory attachment. Completing the build is an AR-15 M4 charging handle and a nitride-finished bolt carrier group made from 9310 alloy steel. The assembly includes a GI Birdcage flash hider that reduces flash signature and muzzle rise, making this complete upper an ideal choice for gunsmiths and freedom enthusiasts.
