I went to the shop a while back to buy a scope base for my new rifle. The shop's catalog suggested a Weaver 2-piece base. I bought it, and the holes are correct, but the bases are so close together that the scope's midsection will BARELY fit down between the rings. I'm guessing there's a one-piece base that will fit that barrel, but I don't know where to find it since my shop couldn't set me up. Any ideas?

Thank you-
