The Nightforce Unimount is designed to remain on the scope at all times, allowing quick removal of the scope or interfacing with different firearms. It is the most accurate Mil. Std. 1913 mount available, incorporating a built-in 20 MOA taper to maximize long-range capability. The Unimount is the ultimate mount for attaching to weapons with an integral Mil. Std. 1913 flat top-type receiver.
