Is there a button to look at the stats for each weapon and compare?
I don't think so. I saw some stats on a Wiki but it seemed those were just assumptions mostly and based on the PC game.
I'd assume 7.62 weapons doing more damage than 5.56, but slower velocity. .45 doing more than 9mm, and so on and so forth based on real ballistics.
Second game after today's patch and I'm currently noshing on my first chicken dinner. What a rush!
Congrats! There really isn't anything around right now that gives this same kind of rush.. man, the feeling of victory at the end of a round is amazing.
