The first thing you may notice about this hunting rifle from German gun maker Christoph Funk is that the rifle has a second breech, a second trigger, a second bolt, and a second barrel. This rather unique gun’s top barrel is chambered in 7x57mm Mauser and its bottom barrel is chambered in .22 LR. According to firearms historian Ian McCollum, who runs ForgottenWeapons.com, this kind of flexibility allows the user to take both medium-sized to large game and small game without having to swap firearms. If you’re worried about the weight of an extra barrel throwing off the rifle’s balance, don’t be. The addition of the second barrel only adds very little to the overall weight and as a whole the .22 action is cleverly integrated with the rest of the weapon.
