Our X-Treme Duty rings and bases are known for their ability to withstand a lifetime of abuse on large-caliber rifles. Our configurable ring top accessories build on this reputation by offering rugged accessory mounts for the additional equipment you need to augment your scope. The MultiMount system was designed to mount red dots for use as a close range sight in conjunction with a primary day optics. However, any accessory can be mounted to the 2 included 3-slot Mil. Std. 1913 rail sections, which can be mounted at 10, 12, and 2 o’clock on the MultiMount cap. Both the MultiMount and RAP are designed to fit the four-screw and six-screw X-Treme Duty rings, Unimounts, and UltraMounts.
