I don't know a whole lot about this, but I would call burris optics at 970-356-1670, I am sure they could tell you if they had a base that would fit your requirements. Also I don't know what kind of red dot you are thinking about but I would check out the burris fastfire 3, it has a lifetime warranty, 10,000 hour battery life, waterproof, parallax free from 10 yd to 150 yd, low battery indicator, automatic red dot intensity adjustment or 3 manual intensity settings. It also has a 1000 Gs recoil resistance, easily stands up to 3.5" turkey loads. Also Customer service is Great.
If that doesn't work out maybe you could have a weaver base put on it, a lot of red dots will work with that, including the fastfire 3.
Post back with what you come up with, I'm sure other members might be interested.
