Colt's monolithic carbine is built around an upper receiver machined as a single piece with the rail, eliminating the joint between the receiver and handguard entirely. That continuous rail surface is why the design earned a following with agencies: an optic and a laser stay in the same relationship to each other and to the bore no matter how the rifle is handled. This one is a 5.56 NATO carbine with a 16.1-inch barrel, a quad rail and front and rear flip-up sights. Colt's manufacturing pedigree on the AR-15 platform needs no introduction. Handles both 5.56 NATO and .223 Remington.
