NVG High Rise Mount By lifting the optic up higher you can clear lights, lasers and any other items that can obstruct your sight picture. With our new NVG mount, we push the boundaries further than before. With a height of 2.33” from the top of your 1913 pic rail to the center point of your optic, you now have the ability to see your irons through the mount. We have also integrated a section of 1913 rail, so you can run magnifiers.
