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.
