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.


Our improvements:- Machined in house in one of our CNC machining centers
- 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.
