When AREA 419 set out to make an ideal scope ring the things they knew they needed to accomplish and do to a degree you won’t find anywhere else on the market is to produce a reliable and true capture of the optic. This led them down a rabbit-hole ultimately arriving on a process that gets you serialized final-bore matched rings with raw aluminum internals for a grip on your optic that is more reliable and more true than anything else made.
Like most rings these begin as separate parts. AREA 419 is making the bases and caps in batches. While many will make these parts send them to anodize and then just assemble they 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 AREA 419's 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.
