The Noveske Chainsaw 16" 5.56mm Complete Upper Receiver is a premium, duty-grade AR-15 upper assembly engineered around a forged 7075-T6 aluminum receiver group. This direct impingement system features a 16-inch 416R stainless steel Recon-profile barrel built with a hand-polished match chamber, 1:7" twist, and a smooth-cycling mid-length gas system. It comes fully equipped with a 15-inch Gen 4 NSR M-LOK free-floating handguard, an ambidextrous Noveske "Love Handle" charging handle, and a standard A2 flash hider. Additionally, it includes a phosphate-coated, full-auto-compatible mil-spec bolt carrier group made from heat-treated Carpenter 158 steel. This optics-ready receiver group drops directly onto any standard mil-spec AR-15 lower receiver platform.
