Overview
This modular offset mount is built for AR15 setups that pair a red dot with a primary optic, giving the shooter a choice of 35 or 45 degree placement without needing extra components. The 35 degree option sits closer to slimmer, smaller scopes, while the 45 degree option offers more room around wider turrets or larger, higher-magnification optics. Mounted to the top Picatinny rail, it keeps the offset sight centered over the bore when the rifle is canted and maintains a lower 1/3 co-witness height. It is a practical fit for hunters and shooters who want a streamlined transition to a close-range aiming option on a scoped rifle.

Considerations & Trade-offs
- Designed for AR15 top Picatinny rail use, so it is not a universal mount for other platforms or rail setups.
- The 35 degree and 45 degree positions serve different optic-clearance needs, so the best fit depends on the scope profile and setup.
- This is a plate-based optic mount, so compatibility depends on the selected Plate #4 configuration and the red dot sight being used.
- Maintains a lower 1/3 co-witness height when canted, which may or may not match every shooter’s preferred sight picture.
