What are your thoughts and whats the easiest way to spot it?
I'm thinking about going and picking up an M91/59
Anything I should watch out for on that?
Thanks

Its not hard to spot, your .30 cal muzzle will look like a .375 or .40, you couldn't possible not see it if you've ever looked down any muzzle.  If your still not sure take a flashlight with you, you should easily see the new "crown" inside.  I didn't understand what counterboring was when I first heard it, basically it just creates a new crown farther down the muzzle where the rifling is better.  Accuracy will improve, but gun value may be slightly less.

thanks i was under the impression that counterboring was not good in terms of accuracy

No, it was done to improve accuracy, it seems the muzzles got wollard out by the steel cleaning rods from what I've read.  I couldn't believe it when I first read about it, but it does make sense.  If there aren't any riflings at the muzzle, you wouldn't hit a barn at 100 yds, counterbore it and create a new muzzle and accuracy will greatly improve.
