My boss at the day job is going to be heartbroken. He thought that he was the first person to think of doing an AR-10 based 12-gauge shotgun, but apparently Rhino Arms has beaten him to the punch. Their new AR-10 based shotgun is a “hot swappable” upper receiver, meaning all you need to do is change the upper and slap in a new magazine and you’re running 12 gauge roounds. No fiddling with recoil springs, no messing with internal parts — nothing.
They’re planning on selling the gun in a package, with a drag bag containing one AR-10 upper, one 12 gauge upper, one magazine each and a lower, so the end user can choose which ammo they want to run that day. All they need is a 9mm upper and you can run 3-gun with just one gun.
