Russian Mosin Nagant, bolt action rifle. I have one of these rifles (I'm not telling how much I paid. My girlfriend will kill me), that went through the seige of Stalingrad and was commandeered by the Nazis. It has roughly carved German and Russian graffito on the stock, as well as several rough swastikas. I fired it once, many months ago. I still have the bruise on my shoulder. Beautiful and practically indestructable, and they take commonly available ammo. A cool piece of history.
