Our Keystone 30mm Scope Rings are the best solution to mount your scope to your rifle or shotgun.
Our Keystone 30mm scope rings work with picatinny and weaver style rails and feature a fully machined crossbolt and nut. Our rings work with all scopes that have a 30mm tube, from brands like Vortex Optics, Nightforce, Athlon, Leupold and more!
Why use our scope rings?
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 installationEGW 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.
Our Keystone Series rings are available for 1", 30mm, 34mm tube scopes.
1" Tube Heights: .850" LOW .990" MEDIUM 1.275" HIGH
30mm Tube Heights: .850" LOW .990 MEDIUM 1.275" HIGH
34mm Tube Heights: .990" LOW 1.275" MEDIUM 1.5" HIGH
Our 30mm Keystone scope rings are sold in pairs.
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.

Not worth the money if you ask me. You will want to rachet the rail screws down. I have retighten these a few times as they just don't hold ... next time am I going to glue the treds

I bought these along with a EGW Picatinny rail for a CZ 457 Varmint. Even with a 50mm objective lens these were more than high enough. Very well made. I would not hesitate to use them on other rifles as well.
