Optimized for 1" tall adjusters, the RMR Footprint Accessory Ring Plate from Trijicon is designed to mount on accessory ring caps that are used for Q-LOC style mounts. The plate can be set at the 12 o'clock position for heads up shooting or at either 45° position for close range shooting through adjusters. It's designed to work with Trijicon Q-LOC and Slim Line style variable power mounts, accessory ring caps, and the RMR to create a full optics solution in one system.
