USED Area 419 Match Scope Rings 30mm Diameter 24mm Height Black. We are making the bases and caps in batches. While many will make these parts send them to anodize and then just assemble we produce around the extra steps. Once these parts return from anodize they are fully assembled placed back into specially produced rail fixtures with the caps torqued to spec over specially made spacers (to give the rings space to torque down on the optic) and final-bored as sets in our world-class machining centers. Rings are then brought off the machine in sets and placed into the laser to mark them as sets with each set being uniquely identified as a match to its precision-bored counterparts.
