EGW saw the need for a US-made, mid-tier scope ring. One that was versatile, robust, and also a great value. They weren't happy with the current options on the market, so they created their own. Introducing the Keystone Series scope rings.
Features:
- Machined in house in one of the EGW CNC machining centers
- 6061 aircraft-grade aluminum
- Anodized matte black finish
- T15 mounting hardware for the ring caps
- Chromoly crossbolt and 1/2" nut for reliable and repeatable engagement
- fits Picatinny and Weaver-style rails
- Horizontally split design allows for easy installation
- EGW rings are measured from where the ring sits on top of the base, to the center of the ring
- Crossbolt torque: 65 in/lb
- Crossbolt nut socket size: 1/2"
- Ring Cap torque: 15 in/lbs

**Note: If your scope has an objective greater than 50mm, or if it has a large power selector knob, EGW recommends 0.990" rings or higher
