Our Assessment: This pre-ban Colt SP1 was manufactured in 1973 and qualifies as a Curio and Relic rifle. Produced by Colt's Manufacturing Company, the SP1 was the first commercially successful civilian AR-15 and closely mirrored the configuration of the early M16. Featuring the classic slickside upper receiver without a forward assist and A1-profile furniture, the SP1 has become one of the most collectible variants of the civilian AR-15. As a pre-ban example from the early 1970s, it holds significant historical and collector appeal.

Chambered in .223 Remington with a 20 inch barrel, this rifle retains the lightweight, full-length configuration that made the original AR-15 famous. In this writer's opinion, the bore rates 9.5 out of 10, indicating excellent internal condition with strong rifling. The action functions correctly.

The furniture rates in Fine Plus condition with little visible handling wear. This rifle retains approximately 98% of its original finish, presenting an exceptionally clean appearance. Included are one 20-round Colt magazine, the original sling, and an M7 bayonet with sheath, making this an especially desirable package for collectors of early Colt AR-15 rifles. Overall, this rifle rates in Fine condition and stands as an outstanding example of a 1973 pre-ban Colt SP1. Please see our photos for a better understanding of condition and good luck with your bids!
