The ArmaLite Rifle-15, or more commonly known as the AR-15, was developed at the request of the United States Continental Army Command to replace the M1 Garand and other battle rifles. The gas-operated, magazine-fed rifle design was sold to Colt shortly after its inception due to financial troubles ArmaLite was facing. After a run of almost 20 years, Colt’s patent expired in 1977, and copies of the once-patented design began cropping up across the nation. Despite patent expiration, the Colt-designed M16, a revised select-fire variant of the original AR-15, remains the service rifle for the United States military today. As a result of the rifle’s military acceptance, Service Rifle matches across the country added slots for the AR-15/M16-style rifle. The subject of this week’s review is a hodgepodge of parts American Rifleman’s Mark Keefe requested to be assembled in order to meet Service Rifle match requirements. To learn more about the AR-15 rifle and the parts used in Keefe’s build, check out this week’s NRA Gun of the Week video.
