Overview
This modular offset mount is built for AR15 rifles and gives the shooter a choice of 35 or 45 degree red dot placement without needing extra components. The 35 degree setting keeps the optic closer to slimmer scopes, while the 45 degree option adds room around wider turrets or larger magnified optics. When the rifle is canted, the setup keeps the red dot centered over the bore and maintains a lower 1/3 co-witness height. It is a practical option for hunters and shooters who want a streamlined transition to a secondary aiming point on a Picatinny rail setup.

Considerations & Trade-offs
- This mount is designed for an AR15 top Picatinny rail, so it is platform-specific rather than a universal optic solution.
- The 35 degree and 45 degree positions address different clearance needs, but the right setup depends on your scope size and turret profile.
- It is intended for use with a red dot sight and a canted rifle position, so it adds a secondary aiming option rather than replacing your primary optic.
- The product description does not specify included hardware or compatible optic models, so fitment should be verified before purchase.
