ADM QD Mount American Defense Manufacturing AD-170-S – Compatible with ThermNight, Hydra and ZULUS HD

The AD-170S is a more compact version of the AD-170.  Made from precision-machined 6061 T6 aluminum and finished with a hard coat T3 Mil-Spec anodize, it features the patented QD Auto Lock™ Lever system, which ensures compatibility with both in-spec and out-of-spec rail systems. The AD-170S was not designed for our scopes but the footprint will mount to all models of our digital scopes, including the ZULUS HD, ThermNight and Hydra series. Available in Black.

Disclaimer: The ADM is very low profile and will lower your optic height from 1.54” down to 1.2”. If you need to raise the optic height back to factory height, a third party riser will be needed. 

This mount works with our optics but it is not made specifically for them. The channel is wider than the ridge under our scopes. The mount will come with M5x8 screws that we supply, do not use the factory mount screws as they are too long or any screws other than the countersunk M5x8. This mount will also shift your optic forward so your eye relief will shift. The Midwest Industries Atlas QD works well as a riser and gives the proper offset reverse cantilever as our factory non-QD mount.
