This is a Public Service Announcement. Thought I would post this here as I am not the seller and had been looking for one of these for two years without luck. Now, Hogsden has several of these available for $60 on E-bay. Another seller has one for sale for slightly more. I don't know why these are available all of a sudden but I needed one for my M40 USMC sniper. Go to E-bay and search for Unertl MST-100 150 Parallax

Excellent.

I have one of the basic flat USO models.

I note this has the studs for resting the unit on an elevation or windage turret....are there any reference marks on the other side to assist with adjusting the zero.

If the other side were marked with angles of MOA that would be the only reason I could see for installing the studs on the tool.
