American Defense Mfg. Holosun 509T QR Low Mount – Quick Release Optic Mount

The American Defense Mfg. Holosun 509T QR Low Mount is a precision quick-release mount designed specifically for the Holosun 509T enclosed reflex sight. The low-profile height positions the optic for lower 1/3 co-witness with iron sights on AR-15 platform rifles, providing a balance between sight picture and backup sight visibility. The auto-locking quick-detach lever allows tool-free installation and removal while maintaining zero return.

Machined from 6061-T6 aluminum with a hard-anodized finish, this mount features American Defense's patented QD system for secure, repeatable attachment to any MIL-STD-1913 Picatinny rail. The proprietary clamping mechanism distributes force evenly across the rail for consistent lockup. Mount includes all necessary hardware for Holosun 509T installation.
