EGW Keystone 34mm Extra-High Scope Rings
EGW Keystone 1.500-inch extra-high scope rings were specifically designed for AR-style rifles and other flat-top platforms using scopes with a 34mm main tube. This configuration provides the highest optic centerline available in the Keystone 34mm lineup for shooters who need additional clearance and a more upright sight position.
These rings are precision CNC-machined from 6061 aluminum at our Quakertown, Pennsylvania facility and designed for Picatinny and Weaver-style cross-slot rails.
Keystone is the flagship of the EGW scope ring lineup, combining a streamlined horizontal-split design, Chromoly crossbolts, secure cap hardware, and 100% American manufacturing.

Designed for AR-Style Rifles
The 1.500-inch measurement is taken from the top of the mounting rail to the centerline of the scope tube. This extra-high configuration was designed to provide a practical optic position on AR-style rifles and other platforms with an inline stock, tall handguard, or high comb.
Why Choose Keystone 34mm Scope Rings?
Precision CNC-Machined
Machined from 6061 aluminum to maintain consistent dimensions and mating surfaces while keeping unnecessary weight out of the mounting system.
Horizontal-Split Design
The horizontal split provides straightforward scope positioning and allows the ring-cap screws to be tightened evenly during installation.
Chromoly Crossbolts
Chromoly crossbolts provide a strong mechanical connection between the rings and a compatible cross-slot mounting rail.
Cross-Slot Compatibility
Keystone rings are designed to mount to Picatinny and Weaver-style cross-slot rails, providing compatibility across a wide range of rifle setups.
Extra-High 1.500-Inch Centerline
The highest Keystone configuration for 34mm scopes provides additional clearance for tall handguards, large objective bells, scope caps, high combs, and piggyback accessories.
Made in Pennsylvania
Keystone rings are 100% American-made and manufactured by EGW at our facility in Quakertown, Pennsylvania.

When Should You Choose 1.500-Inch Extra-High Rings?
Choose the 1.500-inch extra-high configuration when an AR-style or flat-top rifle requires a taller optic centerline, or when the .990-inch low and 1.275-inch medium rings do not provide the needed clearance or shooting position.
Common reasons to select extra-high rings include:
- An AR-style rifle with an inline stock
- A tall free-float handguard or continuous top rail
- A chassis or stock with a high or adjustable comb
- A large objective bell or thick lens covers
- A piggyback red-dot or accessory configuration
- Additional clearance for night-vision or thermal equipment
- A preference for a more upright head position
Minor fitment may be required. Extra-high rings do not automatically guarantee proper eye alignment or compatibility with every rifle. Verify scope positioning, eye relief, objective clearance, and cheek-weld height on the complete setup.

Installation and Torque
Confirm the firearm is unloaded before beginning installation. Inspect and clean the rail, rings, and hardware, then follow the instructions supplied with the rings and scope.
- Tighten the Keystone crossbolts to 65 inch-pounds.
- Tighten the ring-cap screws evenly to a maximum of 15 inch-pounds.
- If the scope manufacturer specifies a lower maximum torque, follow the lower specification.
- Verify proper eye relief, scope position, clearance, and operation of all firearm controls.
Important: Do not exceed the scope manufacturer's published torque specification. Excessive ring-cap torque can damage the scope tube or internal components.
Frequently Asked Questions
What scopes fit these rings?
These rings fit scopes with a 34mm main tube. They will not fit a 1-inch or 30mm scope tube.
Were these rings designed for AR-style rifles?
Yes. The 1.500-inch extra-high Keystone rings were specifically designed for AR-style rifles and other flat-top platforms using a 34mm scope. The actual shooting position still depends on the firearm, stock, scope, cheek position, and shooter.
Will these rings work with a 56mm objective?
The 1.500-inch centerline provides substantial room for a 56mm objective and other large optic configurations. Actual clearance depends on the objective bell's outside diameter, rail, handguard, lens caps, and complete rifle setup.
Can these rings be used on a bolt-action rifle?
Yes, provided the rifle has a compatible Picatinny or Weaver-style cross-slot rail and the 1.500-inch height creates the desired optic position. They may be appropriate for chassis rifles, tall adjustable combs, accessory setups, or shooters who prefer a more upright head position.
How is the 1.500-inch height measured?
EGW measures ring height from the top mounting surface of the rail to the centerline of the scope tube.
Do Keystone rings fit Weaver rails?
Keystone rings are designed for Picatinny and Weaver-style cross-slot rails. Verify the dimensions and condition of the specific rail before installation.
Are the rings sold individually?
No. This product includes one pair of Keystone scope rings.
Can I add an EGW Piggyback System?
Yes. Select the appropriate 34mm piggyback ring cap and the separate adapter plate for the intended optic or accessory. Both components are required for a complete piggyback setup.
