Well we have a modern hunter and a modern varmint and modern magnum in the works but what about the modern shotgun. I see a quick google search shows that ras-12 ammo can be fed through a 308 magwell (or 20 gauge?)I would be in line for an upper!! Regular 12 gauge may fit through the modern magnum magwell but atrs a shotgun upper would be amazing on the hunter. Can you sign me up??
