I just got my new Axis .223. It came with the Bushnell scope on it. I bought some Burris Signature Zee rings for it but the rings won't fit on the pre-installed bases. It seems like the bases are too wide for the rings. What bases can I put on this rifle that will work with the Burris rings? Hopefully something I can find locally and not have to order because I want to take the rifle out shooting this weekend.
