Recoil Magazine recently featured the Sol Invictus Arms AA-12 Sledgehammer. They detailed a bit of the background of the Shotgun and called it "drool-worthy unobtainium." We agree with the drool-worthy part but it is unobtanium no longer! Pre-orders are available now through our Armslist and Gunbroker pages. Thanks for the shout out Recoil!
