SKU: RSR|ARSOOM-BASE Category:

The Patented Arisaka Offset Optic Mount Base provides a modular solution for mounting a red dot sight at an offset position without extra components. The design allows selection between a 35° or 45° offset by reversing the stem between the optic plate and base during assembly. Two plate heights are offered—standard and tall—to match the primary optic height and preserve a consistent cheek weld. The base and optic plates can be reversed for full ambidextrous use, and a range of red dot sights are supported via interchangeable optic plates.
