Complete AR-15 Service Rifle Uppers
Each barrel is custom-turned, threaded, and chambered from a straight cylinder blank for every order. You may pick your choice of chambers from a standard .223 Wylde or .223 CLE chamber in any upper. Keystone Accuracy uppers are hand-crafted and match-proven. They are built with serious service rifle competition in mind and can be found up and down the firing line at rifle ranges all over the United States, including the National Matches at Camp Perry, Ohio.
