Things I liked: Well made and holds scope securely. Greatly aides aging eyes.
Things I would have changed: Nothing.
What others should know: It is a weaver mount which will not fit 11mm or 3/8 dovetail without adapter.
Not sure but 7/8" seems high from the top of the rail to the bottom of the scope! 7/8" is 22mm which is a High Ring profile! If these are medium mounts they should be about 11/16" or around 17 to 18 mm! So I think you need to fix this, they should be around 18- mm
