I used a scope checker but don't know if it was a Hood, the one you show looks as if it has a removable side on the dovetail that attaches to the rail on the rifle. Is that the case? to one I used was not loose it was cut most of the way through and had to be spread to allow clearance to slide on to the rail. This made installation on the rifle hard and messed up the finish on the pictinny base. The completely removable side would be much better.
