Our Assessment: Among the list of desirable, rare, nearly unknown, pre-ban, and collectable AR-15 rifles, this Rock Island Armory Inc. M15 A1 finds itself near the top. Sendra Corp back in the 1980’s began manufacturing AR-15 receivers to directly compete with Colt who nearly had a monopoly on the AR-15. Later down the road several firearms manufacturers began using Sendra receivers in order to “dip their toe” in the world of Armalite Rifles. Companies like Bushmaster and Rock Island Armory purchased many Sendra receivers which they used for their first AR-15 builds. Sendra ended up going out of business and Bushmaster bought their tooling which helped them begin their volume of AR-15 rifles. All Sendra receivers are pre-ban and are loved amongst collectors as they are time tested and have an excellent reputation as many were converted to select fire by class 2 manufacturers before the 1986 ban. This rifle has been given a beautiful set of vintage Redfield Olympic Target Rifle Sights which completes the vintage appeal of this classic rifle.
