How to Choose 34mm Scope Rings

Confirm that your scope has a 34mm main tube before choosing your rings. The main-tube diameter determines ring size, while the outside diameter of the objective bell, barrel contour, rail height, rifle platform, lens caps, and desired cheek weld determine the required ring height.

Height Recommended Starting Point Shop
.990" Low Developed to work with 56mm objective scopes on compatible rifle configurations while keeping the optic as low as practical View Low
1.275" Medium Heavy barrel contours, tall or canted scope bases, and configurations needing additional objective clearance View Medium
1.500" Extra High AR-style rifles, straight-comb chassis systems, and platforms requiring a taller optical centerline View Extra High
Important: A 56mm objective specification refers to the lens diameter, not necessarily the outside diameter of the scope bell. Always account for the complete objective housing, barrel contour, rail, sunshade, and lens caps when confirming clearance.

Frequently Asked Questions

Are 34mm rings compatible with 30mm scope tubes?

No. The rings must match the scope's main-tube diameter. A 30mm scope requires 30mm rings, while a 34mm scope requires 34mm rings.

Will the .990-inch low rings work with a 56mm objective?

The .990-inch Keystone rings were specifically designed to work with 56mm objectives on compatible rifle setups. Final clearance still depends on the objective housing's outside diameter, barrel contour, rail height, and any installed lens caps.

Which 34mm rings should I choose for an AR-style rifle?

The 1.500-inch extra-high Keystone rings were designed for AR-style rifles and other platforms requiring a taller optical centerline and more upright head position.

Do Keystone 34mm rings fit Weaver-style rails?

Yes. Keystone rings use a squared recoil lug designed to fit both Picatinny and Weaver-style rail slots.
