American Defense Mfg. Holosun 509T Co-Witness Mount – Standard Height

The American Defense Mfg. Holosun 509T Co-Witness Mount provides a secure, repeatable platform for the Holosun 509T red dot sight. Machined from 6061-T6 aluminum with a hard anodized finish, this mount positions the optic at absolute co-witness height, aligning the red dot with standard iron sights for a consistent sight picture. The mount uses ADM's patented QD Auto Lock lever system for quick attachment and removal without sacrificing zero retention.

Designed specifically for the Holosun 509T enclosed reflex sight, this mount features a solid top rail interface and eliminates the need for adapter plates. The low-profile design keeps bulk minimal while maintaining strength. Includes all necessary mounting hardware. Made in the USA.
