The Arisaka Offset Optic Mount is a modular, reversible mount that offers 35 or 45 degree offset positions for red dot sights on AR15 rifles.
It is CNC machined from 6061-T6 aluminum, attaches to the top Picatinny rail, and maintains a lower 1/3 co-witness height with the bore.
Plate #4 is the standard height option compatible with optics like Leupold Delta Point Pro, JPoint, Shield RMS, RMSc, Swampfox Sentinel, and SIG Romeo Zero.
