This is a Rare Preban Colt Gov’t Carbine Model 6520 in excellent condition. It is 100% Colt! It has the original finish, which I’d rate at 98+%. The front sling swivel is not attached but does come with the rifle. It was shipped as a complete preban rifle from Colt in June 1990 and has the paper work to prove it. It came from the factory with no sear block, it has the raised magazine fence, the hammer and trigger pins are mil spec and the front pivot pin is the large Colt type. This is a rare find; very few Colt’s have all these features! If interested E-mail for pics and/or questions. Asking $2650. but will consider any reasonable offer! Can't do trades, need the cash!
