I don't remember exactly where I got it, but the C-211 Assault Saboteur looks really nice if you're more into semi-realistic looking rifles.
Man, that looks like it could be a cool one. I wish there were an option to preview weapons; too many times I get a gun that looks awesome in the tiny picture but then turns out to be some strange alien thing.
What was the name of the first orange rifle you get anyways, it's been so long. Not sure if I still have it still in storage.
My biggest (haha) problem is that I'm body type 4, so any weapon smaller than a full sized rifle looks incredibly tiny in my meaty hands.
