The American Defense Manufacturing AD-509T Quick Detach Mount is designed specifically for optics using the Holosun 509T footprint. Precision machined from 6061-T6 aluminum and finished with a Type III hard coat anodize, the mount provides a strong and lightweight mounting solution. ADM’s patented Auto Lock QD lever system allows fast attachment and removal while maintaining secure lockup and reliable return-to-zero on Picatinny rail platforms. The mount is available in multiple height configurations including low, absolute co-witness, and lower 1/3 co-witness to accommodate different rifle and optic setups.
