You can also get the Burris Offset Inserts that go with the Signature Zee Rings. You can pair these to create the same effect as a canted base of 5, 10 or 20 MOA depending on you needs. They cost $15 which is a lot better than a quallity base. No right or wrong answer here just another option. I use them in conjunction with the Burris Tactical (steel) two piece bases. The combo creates a nice stable platform.
