I was needing some help with Scope rings. I want to mount my new Nikon in Burris Signature rings because of the insert and stress free alignment on the scope. One catch, i need a certain kind of rings. I don't want to remove the Weaver bases that is already on the rifle, so i need to know if Burris makes signature rings with the extended front and standard rear in the Weaver style??? I saw at midway that they make weaver style in signature, but I need them to have the extended front and standart rear. Thanks for the help.
