Manufactured by Colt for commercial sale, the AR-15 Model 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 a threaded muzzle and three-pronged flash hider on the "MP" marked barrel, bayonet lug on the front sight base, triangular handguard, checkered pistol grip and fixed buttstock, sans trapdoor. The early "slick side" pattern upper lacks provision for a forward assist, with a short casing deflector and is marked with a boxed "C" on the front right side near 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 auto sear, and a right-handed "SAFE"/"SEMI"/"AUTO" selector. The bolt and bolt carrier are both matte phosphate finished, the former marked "MP" and the latter serrated for a forward assist, and a one-piece recoil buffer is installed. Included with the lot is an extra magazine, a round ribbed forearm set, an extra bolt carrier group, and an assortment of small parts.
