The movie didn't suck. Didn't rock either but as far as a children's book adapted to movie it was better than "Eragon".
However the armorer did some really good work arming the cast with some nice hardware. From my one watch through I identified the obvious SMLE's and Mauser rifles, and of course Sam Elliot's winchester lever rifle (a full length 94 if my guess is correct). I remember seeing one Mosin Nagant, but I would have liked to see more of them.
This is going to be a fun movie to rewatch and try to ID all the weapons used :)
