The Nightforce UniMount is the ultimate mount for attaching to weapons with an integral Mil-Std. 1913 flat top-type receiver. The Nightforce UniMount allows for quick removal of the scope for interfacing with different firearms - such as an AR-15 flat-top and Barrett .50cal. rails. These are manufactured to Mil-Std. 1913 specifications and are CNC machined from 7075-T6, with beta series Titanium crossbolts and jaws. The UniMount incorporates a built-in 20MOA taper to maximize your rifles long-range capability and like all Nightforce rings, the UniMount is 100% microradiused and inside edges honed to prevent the rings from scratching your scope tube.
