A/T Optic Riser 525-13 is approximately 5-3/4" long and covers the entire length of an upper receiver and offers one more recoil slot than the upper. This riser has 13 recoil slots (14 lugs). It can be used with any combination of sights, NVG, or thermal which would fit on an upper receiver and the additional slot gives the user some spacing flexibility. Optimized for close combat ranges, the BCM A/T Riser creates a platform that raises the centerline of attached optics and magnifiers by 0.525 inches which raises typical lower 1/3 optics to approximately 2.16 inches height and absolute co-witness optics to approximately 1.93 inches height. This additional height enhances the trained end user's situational awareness, and further, makes it possible for them to take better aimed shots if they are using the optic in conjunction with night vision or other PPE systems.
