Specifically designed for left handed or left eye dominant shooters Please see 6110MR for right handed or right eye dominant shooters. The Warne 45 Offset Reflex Mount Is designed to offer a reflex sight mount that fits the most popular optic mounting patterns while seamlessly blending into the top rail of a rifle ensuring the maximum amount of space to clear a scopes eyepiece or zoom ring. The height and angle of the mount place the optic in a position to allow for fast target acquisition. With the increasing number of electro optics being used finding a compatible mounting system can be confusing. We designed our modular Red Dot Riser to t a wide range of different optics based on the mount footprint. All riser mounts that we offer share a robust mounting base while the top is engineered specially for different red dot styles.
