Our Assessment: In beautiful condition that only pre-ban platforms can glow with, this AR-15 is the epitome of basic, but not in a bad way. Basic in this case means pre ban factory configuration, reliable, and ready to use. The SP-1 is about as close as you can get to the classical image and feel of an M-16 rifle. Colt is the king of these rifles, having been the original issuer of the concept to the military. With a triangular forearm and solid A1 features, with some highly desirable Colt collectable accessories, you can give this arm the 21st-century treatment at the range or keep it as a show-and-tell piece. Either way, ya gotta bid on it first!
