Experimental German rifle made in 1944, the first of the roller-lock delayed blowback designes that eventually became CETME and HK .308s. This one is in 7.92×33. It’s crude, simple and works well. Recoil is minimal, with two distinct stages. Sights are simple and I found them hard to see on dark backgrounds.
I shot a couple of rounds sitting at 25 yards to check zero. Zero checked out. Ammo: 123gr FNM.
