Each of the guns advertises a "beveled" mag well. I don't think that any of the three delivered what I was/am looking for. I would have liked to see the metal at the outside tapered to be much thinner, almost a knife edge. None of these has that, and I understand that it has to have some meat there otherwise it would become damaged. I am not a fan of extended mag wells, although adding one to any of these would be an option for others.

Of the three, the Wilson seems to be the best executed and the most functional. The Brown is too short and sharp, and the Yost is too long and gentle. The Wilson is also the only one of the three that addressed the rear. While it's no Chuck Rogers treatment (my absolute favorite that's out there), at least they broke the edge a bit.
