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 adding extra components. The 35 degree option sits closer to slimmer, smaller scopes, while the 45 degree option leaves 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 setup piece for hunters and shooters who want a streamlined transition to a close-range sighting option.

Frequently Asked Questions
What does this offset optic mount do?
It is a modular mounting solution for a red dot sight that lets the user choose either a 35 or 45 degree offset position without needing additional components.
Is this mount meant for an AR15?
Yes. The product description says it is designed to attach to the top Picatinny rail of an AR15 rifle.
Why would I choose the 35 degree position instead of 45 degrees?
The 35 degree position brings the red dot sight closer to slimmer, smaller scopes. The 45 degree position is intended to provide additional clearance around wider turrets or larger, higher magnification scopes.
Does the optic stay centered when the rifle is canted?
According to the description, when the rifle is canted to use the offset red dot sight, the optic remains centered over the bore and maintains a lower 1/3 co-witness height.
