The height is not all that bad say 40-50mm objectives but for smallerscopes it may pose a problem. Another solution which I may be switching to soon is purchasing a BSquare weaver rail from pyramydair.com for about $40.00. It should fit on the gamo receiver groove and lower the scope profile to about half what it is with this combo. I posted the picture I posted here on pyramydair.com's website but they removed it for some reason. Seeing that they market the freaking thing to work with whisperish gamo rifles, at least leave the picture there and let people see what they are getting themselves into if they decide to buy one. I am using mine for the marketed purpose and I was not trying to make people not buy them, just share in my experience by showing an example. In my opinion, when you compare how this mount fits on a diana rifle vs a gamo, the gamo leaves you a little disappointed. I feel that good ole paul capello's review video should have referenced that. I realize now he's not an honest reviewer because he never says anything bad about anything he reviews. Of course, I wouldn't either if I was paid hard cash money. However, he didn't happen to have any gamo's lying around? I mean, he's Paul Capello for crying out loud. LOL! He did mention that it would work with a Gamo but did not display the fit at all in the review. I should have known.
