Arisaka Defense Offset Optic Mount Base — Black

The Arisaka Defense Offset Optic Mount Base is a modular mounting solution that places a red dot sight at a selectable 35° or 45° offset without extra components. Reversing the stem between the optic plate and base sets the mount angle while maintaining vertical alignment over the bore at both positions. Two plate heights are offered—standard and tall—to align the offset optic with your primary sight for a consistent cheek weld. The base and optic plates are reversible for ambidextrous setup and support a wide selection of red dot sights via interchangeable optic plates.
