I'm considering a MRC Extreme Vantage due to the Mauser CRF action, 100% SS and synth stock, all features I was looking for my next DGR.

It's hard to get any reliable feedback on the quality and accuracy of this model.

So, anyone can share some feedback on it? First hand experiences will be greatly appreciated.

Thanks in advance for any help.

The guys over on 24 hour campfire have done a few MRC group buys, though nothing in the big bore category. I think the rifles they bought should be similar enough to give you some data. There are a number of threads over there about use and reviews... just run a search.
