Optimized for close combat ranges, the BCM A/T Riser creates a platform that raises the centerline of attached optics and magnifiers by approximately 1/2 inch. 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.Interfacing with the upper receiver using the same low-profile A/T system used in our Optic Mounts, not only reduces snag hazards but makes the entire length of rail usable for either bolt-on or QD attachments. Further, the low profile A/T interface enables mounting accessories with Mil-Std 1913 attachments anywhere on the stalk of the riser platform allowing end users to fine tune placement of optics, magnifiers, and other accessories.Each A/T Riser is machined from aircraft aluminum alloy, hard coat anodized per Mil-A-8625F. The steel alloy clamp is hardened with Nitride coating for maximum stre...
