Excellent plus, retaining 99% original black anodized and oxide finishes with limited minor handling marks. The furniture is also excellent with limited minor handling evidence. Mechanically excellent. It would be difficult to find a higher condition three-digit, 1964 production Colt AR-15 SP1 rifle than this example!
