Manufactured by Colt for commercial sale, the AR-15 614 automatic rifle was patterned very closely after the early military issued M16 rifle, with the chief difference being in the markings. Post front and two-leaf peep rear sights, with the three-prong flash hider on the "C" marked barrel, bayonet lug on the front sight base, triangular handguard, checkered pistol grip and fixed buttstock, sans trapdoor. The early "slickside" pattern upper lacks provision for a forward assist or a casing deflector and is marked with a boxed "C" on the front right side over a "VP" stamp, while the lower has a fenced magazine catch on the right, and is marked on the left with the three-block AR-15 trademark, "MOD.614" model marking, and Colt address, the latter spaced to accommodate the pin for the safety sear. The bolt and bolt carrier are both matte finished, with the latter serrated for a forward assist. The buffer is of one-piece construction with a plastic tip. With an extra magazine.
