Product Description
The patented Arisaka Offset Optic Mount Base is a modular, low-profile solution for adding a red dot at a 35- or 45-degree offset on your rifle. Designed for the top Picatinny rail, the mount’s unique geometry keeps the optic vertically aligned over the bore and maintains a consistent height whether set to 35 or 45 degrees. The base is fully ambidextrous—simply reverse the base and plate during assembly—and pairs with interchangeable optic plates in two heights to match your primary optic for a seamless cheek weld and fast transitions.
