Meprolights quick-detach (QD) adaptor Kit utilizes the existing rear dovetail slot for sights to mount the adaptor to hold the Meprolight MicroRDS or any other red dot optic on the market. Now almost every pistol can use a red dot optic without the need to drill and tap mounting holes on barrels or slides. The adaptor mounts directly to a Meprolight TruDot, self-illuminated sight which also functions as a back-up sight should the shooter want to remove the red dot optic. Designed as a primary pistol optic; it can also serve as a backup or a secondary CQB sight on rifles and shotguns.
