The Nightforce MultiMount was originally designed as a platform for close-range sights to be mounted in conjunction with a primary riflescope. The MultiMount offers far more versatility, however, functioning as a user-configurable system providing a rock-solid base for any Mil. Std. 1913 accessory that will fit. Designed to replace the top half of an X-Treme Duty ring, the MultiMount allows placement of a Mil. Std. 1913 rail at the 45 degree left, 45 degree right and/or 90 degree up positions. Two rail sections are included along with mounting hardware.
