Question: Will this work with a Sight Mark Ultra Shot Pro Spec site?
Document: I bought this to use with my eotech on my ar 15. The ad was right, the mount isnt really sturdy but the magnifier itself is great. Crystal clear and it doesnt distort when you turn the power up. It turns a close range rifle into a medium to long range weapon with a turn of a knob.One other thing, you couldn't ask for better customer service. While tightening the mount to the rail on my ar,  I over tightened the bolt and broke it.
Gun and Run (Deca-01) Red Dot Variable Magnifier 3X - 10X for Eotech Only works great on my rifle behind an Eotech. Takes up a good deal of rail space. Keep that in mind.
Easy as that, no charge just a simple email and done.If youre looking forva magnifier, and youve got an eotech,  this is the smart purchase
Answer: no
