Personally, I always go with the 1" base and on this kid, I'd stick with Weaver, weaver style. The 1", will give you better footing. I like the Weaver Quads and you are going to make sure your get the proper height. You did not list which model you got and on my Target model, I mounted a 50mm objective scope. ....i just need to know what kind of scope rings I need to buy. the ones i have wont fit?
