Our Assessment: The Colt SP1 is a classic rifle that represents the first civilian-legal iteration of the AR-15, staying true to Eugene Stoner’s original lightweight design. Featuring a “slick side” upper receiver without a forward assist, a 20-inch barrel, and a triangular handguard, the SP1 closely mirrors the early M16 models issued during the Vietnam War era.
This particular example is in Excellent condition, retaining about 98% of its original finish. The bright bore with sharp rifling ensures that this rifle remains a capable shooter. The inclusion of two original 20-round magazines and a black sling enhances its desirability. These rifles are always going up in value, so get them while you can.
