mosin-nagant 

The Mosin-nagant is an old school bolt action rifle from Russia. Originally designed by a drunk Russian engineer and an even more drunk Belgian gunsmith, who drew up blueprints on napkins in the back of a pub somewhere in Siberia in a vodka-induced stupor. The Mosin-nagant fires the 7.62x54r cartridge, which can kill a polar bear at a thousand yards and keep going right through the tree he was standing in front of. The Mosin-nagant was used by the Russians in both world wars, so it's killed more Germans than collisions on the autobahn and under-cooked sauerkraut combined. Surplus Mosins can be found at gunshops in the States for like a hundred bucks on sale, and ammo is cheap surplus, so this is what real men shoot who don't want to drop $1299.99 on an AR-15 which fires a .22 round and that's made out of recycled milk jugs and Legos. Many of them come with a bayonet that's roughly the size of the sword William Wallace used in Braveheart. In the absence of gun oil, you can clean a Mosin by pissing down the barrel and wiping the bolt off with a dirty rag that you found on the floor in a Grease Monkey. Try that with a rifle that was designed less than 50 years ago.

Joe: " I need a rifle that is ten feet long and fires anti-tank rounds, but Ive only got 200 dollars!"

Ivan: "Amerikan comrade, you need mosin-nagant . Spend 100 on the rifle, fifty on case of ammo, use rest for vodka!"

In Soviet Russia, rifle fire you!!!
