My Montana in 308 Win has had a little more done to it besides painting the stock. I built up the stock in a few areas to make it fit me a little better and cut the barrel back a couple of inches to make it a little more handy. The barreled action was cerakoated black and then the stock painted. I've been more than happy with the looks and it shoots better than ever.
I like the way that one looks. I'd put a little tan spot on the barrel.
I actually like the way my Montanas look from the factory. Haven't painted either one.
