The Arisaka Defense Offset Plate, Holosun 509T For 1.9" To 2.2" Scope Mount is a dedicated tall-height optic plate designed to interface the Holosun 509T or HE509-RD with the Arisaka Offset Optic Mount base. CNC machined from 6061-T651 aluminum and finished in a durable hard coat anodize, Plate #14 provides a precise footprint and secure mounting surface while matching popular 1.9" to 2.2" scope mount heights.

This offset plate is ideal for shooters who run a magnified optic as their primary sight and want a clean, lower-third co-witness red dot option for closer targets or faster transitions. When paired with the Arisaka Offset Optic Mount, it allows the 509T to sit at a consistent height and angle relative to the main scope, supporting comfortable cheek weld and smooth movement between optics. Arisaka is known for thoughtful engineering and meticulous machining, resulting in mounting solutions that are both robust and refined.
