The EGW 34mm Keystone Rings in .990" medium height deliver solid American-made scope mounting without the premium price tag. Built in-house at EGW's CNC facilities from 6061 aircraft-grade aluminum, these rings are engineered for hunters and shooters who demand reliability and repeatability without complexity. The horizontally split design makes installation straightforward on any Picatinny or Weaver rail, while the chromoly crossbolt and half-inch nut provide the secure, repeatable engagement that matters when your shot counts.
EGW designed the Keystone Series to fill a gap they saw in the market: rings that balance versatility, durability, and value. The medium height suits 34mm tube optics mounted on rifles where you need a clean sight picture without going tall or compact. T15 hardware on the ring caps ensures consistent clamping, and the in-house machining means tighter tolerances and fewer surprises on the range or in the field.
Whether you're mounting a premium 34mm tactical scope, a mid-range hunting optic, or anything in between, these rings won't demand a second mortgage. They're designed to stay put, season after season, on your workhorse rifle.

Frequently Asked Questions
What scope tube diameter do these rings fit?
These are designed for 34mm tube scopes. EGW Keystone rings are also available in 1-inch and 30mm sizes if you need a different tube diameter.
What rail systems are compatible with EGW Keystone rings?
These rings work on any Picatinny or Weaver-style rail, making them versatile across most modern rifle platforms.
What does the .990" medium height mean?
Height is measured from the top of the rail to the center of the ring. The .990" medium height is a common setup that clears most rifle receivers and offers a comfortable, unobstructed sight picture on most optics. EGW also offers low (.850") and high (1.275") options for 34mm tubes if you need different clearance or viewing angles.
How hard is it to install these scope rings?
The horizontally split design makes installation straightforward—no complex steps or special tools required. The chromoly crossbolt and half-inch nut provide secure engagement and are easy to adjust by hand or with a standard wrench.
