I have the right aimpoint mount, according to larue site, for night vision compatability. It is the medium mount. I also have the pvs mount which states it is designed for the comp series. After mounting, it appears as though the pvs 14 mount places the unit higher than the comp M4. The ring is also extremely difficult to get over the pvs objective. You would need to put a flathead screwdriver between the opening of the ring to get it on there withought scuffing the mount or the pvs14. I bought the mount direct from larue. Normal??
