Olympic Arms has been in the AR-15 business since 1982 and is known in the industry and among consumers as an innovator in the field. Olympic Arms was the first AR-15 manufacturer to introduce flat-top upper receivers, free-floating aluminum hand guards, pistol caliber conversions, and AR-15 based pistols. Olympic Arms is one of the only AR-15 manufacturers that makes every component in-house, ensuring that each and every piece of their rifles meet the rigid specifications of military, government and law enforcement agency contracts. This AR-15 Carbine features a matte black 16-1/2" barrel with a flash hider, an adjustable OD green synthetic stock, a Picatinny quad forearm, a carry handle, a left side-mounted 2-position safety, a folding leaf peep rear sight with an adjustable front post sight, and a 30-round magazine. Its stock, metal, and bore are all in very good condition.
