A buddy of mine was givin this thing. It’s H&K stamped and says it’s made by Benelli. I don’t know much about shotguns but I know it’s at least 10 years old. It has a twist knob in front of the foregrip that can go from semi auto to pump. Sorry for the bad pics, they’re from my shitty work phone. Any info would be appreciated. Curious to find out more. Thanks
