Guns America has a write up on this new gun that is an inertia driven , newly choked, blued or cammoed, and soon to be out. It isn't the old Browning design at all but it is a humpback. You can probably buy one for $699.95 but I don't know if you put a 1 or 2 in front of the six.
There are differing reports as to whether or not they have the magazine assist on the side. Their cammoed version looks good. I am not sure if the stocks and forearms on the blued versions are walnut or not but have reason to believe that they are.
The new choke is designed to keep foreign matter from getting into the threads using a seal of some sort. Looks like there will be a new choke design that may be confusing to some.I do not know if it is invector + or not. I wonder if Briley is the daddy of these chokes.
