I can not identify what kind of Mauser rifles used in those screenshots. This rifles have straight bolt handles and some other form of stock. So maybe it's not Karabiner 98k.
It's odd they would've have real K98ks. You'd think Russian armorers would have plenty of them. I also see the movie was filmed in St. Petersburg, like Downfall, which had plenty of K98ks. --Funkychinaman (talk) 21:05, 25 July 2013 (EDT)
Czech Mausers had straight bolt handles. And Russian armorers must have a lot of different Czech arms
BTW, a large number of different weapon was used in this film. Only small part of this weapon can seen in film trailers. Bednardos (talk) 11:40, 26 July 2013 (EET)
