EGW Keystone 30mm High Scope Rings
EGW Keystone 1.275-inch high-profile scope rings position a 30mm optic higher above the mounting rail when additional clearance or a higher sight line is required. 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.
This Configuration
Scope tube: 30mm
Centerline height: 1.275 inches
Profile: High
Rail type: Picatinny or Weaver-style
Quantity: One pair of rings
Designed for Additional Height
The 1.275-inch measurement is taken from the top of the mounting rail to the centerline of the scope tube. This height is commonly considered for flat-top platforms, chassis rifles, large objective bells, tall handguards, adjustable combs, and other setups requiring additional clearance or a higher optic position.
Why Choose Keystone 30mm 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, giving shooters flexibility across a wide range of rifle setups.
High 1.275-Inch Centerline
The high centerline provides additional room for large objective bells, tall handguards, scope caps, heavy barrel contours, and rifle configurations that need a higher optic position.
Made in Pennsylvania
Keystone rings are 100% American-made and manufactured by EGW at our facility in Quakertown, Pennsylvania.

When Should You Choose 1.275-Inch High Rings?
Choose the 1.275-inch high configuration when the low or medium Keystone rings do not provide enough clearance, or when the rifle requires a higher optic centerline for a comfortable and repeatable shooting position.
Common reasons to select high rings include:
A flat-top rifle or chassis configuration
A tall or adjustable stock comb
A large objective bell or thick lens covers
A heavy barrel or tall handguard
Additional bolt-handle or action clearance
A piggyback optic or accessory configuration
A preference for a more upright head position
Minor fitment may be required. High rings do not automatically guarantee proper eye alignment or clearance on every rifle. Measure the complete setup and verify that the optic can be positioned for proper eye relief and a consistent cheek weld.

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 30mm main tube. They will not fit a 1-inch or 34mm scope tube.
Are these rings intended for AR-style rifles?
The 1.275-inch height is commonly used on flat-top rifles and can provide a more suitable sight line than low rings. Proper height still depends on the rifle, stock or brace, cheek position, scope dimensions, and the shooter's preferred head position.
Will these rings clear a 56mm objective?
The high centerline provides substantial objective clearance, but fitment cannot be guaranteed from the listed objective size alone. Measure the objective bell's outside diameter and account for the rail, receiver, barrel, handguard, lens caps, bolt handle, and scope controls.
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 1.275-inch height creates the desired clearance and shooting position. High rings are often considered for chassis systems, adjustable combs, heavy barrels, and specialized optic setups.
How is the 1.275-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 30mm piggyback ring cap and the separate adapter plate for the intended optic or accessory. Both components are required for a complete piggyback setup.
