The rings are great. I have used these several times when the bases do not line up with the barrel. Center using the rings and then I have full adjustment with the scope rather than using up the scope adjustment to correct the base/barrel misalignment. My problem is with the internet site. There are no demensions given for the rings - low, medium, high, extra high. I had a set of extra high which were too high for what I needed. I was looking for rings not quite as high so I ordered a set of high and medium rings. Both of these proved too low for what I needed. There is a big difference between the extra high and the high rings assuming Optics Planet sent me what I ordered. It is not an even progression from extra high to low. Low, medium, and high have rather even steps between them and then there is a big step up to the extra high. Bottom line is I now have two extra sets of rings for which I have no use
Pros: Windage Adjustable, Secure, Lock Up Tightly
Cons: Watch Out - Extra High is MUCH Higher than the High Rings
