Nikon M-223 Mount and Scope Rings are perfect for your AR rifle. The Nikon M223 Mount is made to work with the Nikon M-223 and Coyote Spcial Rifle Scope series. This paired set of Rifle Scope Rings is manufactured with the same high level of quality that hunters expect from from Nikon. This Nikon Scope Mount is specifically designed to hold the M223 Riflescopes, and mounts on the Picatinny rails found atop most flattop AR Rifles, as well as Weaver rail bases. The Nikon M223 Scope Rings feature lightweight alloy construction, with a built-in 20-MOA incline to maximize elevation for extreme long range shooting.
