  • Product Details

    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

    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

    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.
