We saw the need for a US made, mid-tier scope ring. One that was versatile, robust, AND also a great value. We weren’t happy with the current options on the market, so we created our own. Introducing the Keystone Series scope rings.
Machined in house in one of our CNC machining centers
6061 aircraft grade aluminum
T15 mounting hardware for the ring caps
Chromoly crossbolt and ½” nut for reliable and repeatable engagement
Fits picatinny and weaver style rails
Horizontally split design allows for easy installation
Our rings are measured from where the ring sits on the top of the base, to the center of the ring.
Our Keystone Series rings are available for 1″, 30mm, 34mm tube scopes.
1″ Tube Heights:
62000 – .850″ LOW
62001 – .990″ MEDIUM
62002 – 1.275″ HIGH
30mm Tube Heights:
62100 – .850″ LOW
62101 – .990 MEDIUM
62102 – 1.275″ HIGH
34mm Tube Heights:
62200 – .990″ MEDIUM
62201 – 1.275″ HIGH
62202- 1.5″ EXTRA HIGH
If your scope has an objective greater than 50mm, or if it has a large power selector knob, we recommended .990″ rings or higher.
One set of rings weighs in at approximately 4.8oz.
We recommend that you torque the crossbolts of our Keystone Rings to 65 inch pounds, and the top screws to 15 inch pounds.
