Colt is where the AR-15 came from, and a Colt-marked M4 carbine still carries weight for exactly that reason: this is the original manufacturer building the rifle to the specification it wrote. The 16.1-inch barrel is the classic carbine length, chambered for 5.56 NATO and .223 Remington.

This configuration wears a quad rail handguard with flip-up front and rear sights, the setup that defined the duty carbine for a generation and still works perfectly well. Rails on all four sides mean lights, lasers, and grips mount wherever you want them. Black finish throughout.
