Manufactured in 1965, ahead of the BATFE's rolling 50-year definition of a Curio and Relic Long gun, with a proper arrangement of early AR-15/M16 features. 3-prong flash hider and a bayonet lug on the "12" marked barrel, with an elevation adjustable post front sight on the gas port assembly and a 2-leaf windage adjustable rear sight. The AR-15 nomenclature and Rampant Colt logo are present on the lower receiver, and the upper receiver is properly without a casing deflector or forward assist. The bolt carrier is properly devoid of serrations for the assist, with a "MP" marked bolt head and a two-piece recoil buffer. Fitted with a vented triangular handguard, checkered pistol grip and a fixed buttstock with a rubber buttplate and no storage compartment. Magazine not included.

Very good, with 85% of the original matte black finish, showing areas of brown patina on the dust cover and screws, wear on the carry handle consistent with a Colt scope mount, bright edge wear and mild handling marks. The stock is very good, with some light scuffs and wear. Mechanically excellent.
