I see two Gamo .177 Pellet rifles, an 870 wingmaster 12, a Remington Spartan O/U 12, 9 underfolder AKs (x39), 2 pocket-pistols (.32 or .380 are my guess), what looks to be an old S&W .38, a 3-9x40 Leupold Scope, and some form of single barrel break-action shotgun (looks to be a 20). And the one with those kids has that strange .22 cal "trainer" AK.
It seems that when they start using O/U Shotguns with 28" Bbls, that they might be getting a little desperate as to what guns they have left. Not that those Remington Spartans are anything special--they're built in Russia, though, which might explain their existance.
