When shooting at extreme ranges, many shooters find their riflescope lacks the necessary elevation travel. The Nightforce Wedge Prism is offered in 2 variants, 50 MOA or 100 MOA, that install forward of the riflescope to increase the effective elevation travel. The Wedge Prism optically shifts the incoming image to the riflescope by a precise elevation value, which directly adds to the available elevation travel within the riflescope.Features:50 MOA/14.5 MRAD or 100 MOA/29.1 MRAD elevation shift variants available for extremelong-range useQuick Detach MIL-STD 1913 attachment ensures consistent elevation shift when installedin the fieldCompatible with all brands of riflescopesExact elevation shift measured for each unit and engraved for reference in the fieldIncludes: MOLLE padded carry case, flip cap lens cover, lens cleaning cloth.
