Description
Ergonomic performance meets compact power in this side-charging 5.56 NATO complete upper.
This AR-15 Complete Upper is a high-value, “ready-to-run” solution for your next AR pistol or short-barreled rifle (SBR) build. Chambered in 5.56 NATO, this assembly features a 10.5-inch M4 contour barrel crafted from heavy-duty 4150 Chrome Moly Vanadium steel, offering exceptional longevity and heat resistance under a classic parkerized finish. Its versatile 1:7 twist rate delivers excellent stabilization for a wide variety of bullet weights, while the carbine-length gas system ensures smooth and reliable cycling.
Engineered with a Gen2 right-side charging handle, the flat-top billet aluminum upper receiver offers superior ergonomics, making weapon manipulation and clearing fast and effortless. Up front, the barrel is wrapped in the innovative Talon 10″ M-LOK Split Rail handguard—slashing total rail weight by 30% compared to standard M-LOK systems without sacrificing accessory real estate. Completed with a micro flash hider and a full E9310 bolt carrier group, this complete upper assembly is ready to pin directly onto any mil-spec AR-15 lower right out of the box.
