Description
Arisaka Defense OOM-BASE is an offset optic mount base that supports a red dot sight at a selectable 35 or 45 degree offset. The mount uses modular geometry to position the optic vertically over the bore while keeping the height consistent at both offset angles.
Key features
- Select 35 or 45 degree offset by reversing the stem between the optic plate and base during assembly.
- Two plate height options are supported: standard plates for 1.5 in to 1.8 in, and tall plates for 1.9 in to 2.2 in.
- Base and optic plates can be reversed for full ambidextrous use.
- Designed to align the optic for a consistent cheek weld when transitioning between a primary optic and an offset red dot.
- Interchangeable optic plates support a wide selection of red dot sights.
