AR15 Olympic Arms UM-1 Ultramatch Rifle Semiauto 223 bull bbl

 

If you are searching for accuracy the UM-1 is recommended. It comes with our renowned Ultramatch broach cut stainless steel barrel chambered with minimum SAAMI reamers made by Clymer for optimum accuracy potential. We’ve seen ¼” groups and smaller when used with the proper load, bullets, and barrel. This is the rifle SWAT Magazine called “the most accurate AR target rifle ever made.” The UM-1 comes standard with bull barrel and picatinny gas block. Also available as a completely assembled, headspaced, and test fired upper receiver unit.
