Got my EGW base today. I got it as a freebie being a mod on mossbergmvp.com, but it would have been well worth the money if I were having to spend it. I've kind of used this as a budget tack driver .223 rifle. I can't ask for any better by any means from something in this price range either. Its consistently delivered 3/4" 3 AND 5 shot groups with Hornady V-Max 55gr rounds. Bang for the buck, for under $700 for my whole setup, I don't know that you can get another centerfire rifle to shoot better.
Here she is with the new base:
