***Minor Scratches / Blemishes***

Our Keystone 34mm Scope Rings are the best scope rings, they offer the best value and are made in the USA. Choosing the right scope rings can be tough, but we made it easy with our Keystone 34mm scope rings. They fit both picatinny and weaver rails and are machined with a full cross bolt to give you the confidence you need when mounting your scope. These 1.275" Medium 34mm scope rings will work with most scopes that have an objective lense larger than 56mm.

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
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
EGW Keystone rings use a Fiber Washer so the nut does not mar the finish on the clamp!

Our rings are measured from where the ring sits on the top of the base, to the center of the ring.
