I think we need a bit more info on what your intended use is. If the sight calls for a 34mm ring set then any 34 mm rings will do as Long as they are high enough to allow for use of the optic on the rifle.
Why exactly do you need the quick release? If you are going to use the optic from rifle to rifle, or want to store the rifle a certain way without the optic attached, ok that make sense, but Imo quick release is kind of gimmicky and just adds weight if one jsut wants quick release for the sake of having quick release. Again my opinion only.
American defence does make good rings, no doubt there, but just make sure that if you go with a different set of rings that they are well made and keep the site on zero. I would rather pay for a good set of rings then a ####ty set twice over. Let us know!
