Ditto on the M1919.
All I see is a bunch of crappy AK magazines, an AR, a Dragunov or PSL, a couple of bolt actions...
Second pic shows "something" that takes some large cartridges. On the left hand side. Receiver is covered by cartridges though. It could be a Barrett, or it could be an old Lahti or something.
This is not an impressive sting. All I see are magazines. Kinda dumb. The fact they have to show off a couple of beater bolt guns is pathetic. Moreso by the fact they have to hide their faces in baklavas while doing so.
