I ended up going with a full Magpul setup. The mount, sling and clip. Used uncle mikes for the rear sling. I like the way it works and while its a bit of a pain to take the mount off to remove the barrel I think it will be fine.
Picked up a 20" 12 gauge and want to add a sling. I don't care for the end of the magazine setup with the longer barrel. I am going to go with the Magpul clamp style mount. Courious what folks are using at the stock end. Should I just put a swivel on the factory stud point? Add something else...
