Nost: Yup. HK91 (civilian variant of the HK G3). Magazine is out of the weapon in the picture. I don’t recognize the scope setup, other than it’s a big mofo.
HK makes a sniper rifle, the PSG1, that is incredible. Built on the same chassis as the G3 and a semi-auto.
Germans definitely know their stuff when it comes to beer, autos and weaponry. And how to fit completely unmentionable things into sausage casings.
