The Show Stopper 16.5-inch AR-15 Complete Upper Build from Davidson Defense is engineered for precision and reliability, chambered in 5.56 NATO. This upper features a 16.5-inch "Satellite" barrel with a medium profile constructed from 4150 Chrome Moly Vanadium steel, finished in nitride for added durability. The barrel has a twist rate of 1:7 and utilizes a mid-length gas system with a micro low-profile gas block.
At the muzzle, the Breek Arms Plan B Scorch 3-prong flash hider (1/2x28 thread pitch) effectively reduces visible flash. The upper receiver is made from 7075-T6 aluminum with anodized finish, incorporating M4 feed ramps for reliable function. The setup also includes a black aluminum M-Lok handguard and a mil-spec AR-15 M4 charging handle. This complete upper build is ideal for gunsmiths looking to craft a high-performance AR-15 rifle.
