- Full metal upper and lower receiver - Receiver has integrated carrying handle and adjustable rear sight aperture - Has engraved Colt trademarks with the text - Receiver has matte black finish - Minor cosmetic marks on the metal - Includes all body pins and magazine / bolt release - Includes M4 length outer barrel with skinny 7 hole handguard NOTE: The lower receiver has the text M4A1 instead of M16A2. It was like this when I bought it even though the seller marked it as M16A2
