OK that sounds right. These other stats seem so low that it is irrelevant... I swear it scopes in faster than other snipers which is why I love it. A 25% increase sounds right. It defiantly makes a difference believe it or not. Plus it has low sway so I can scope in faster and be on target faster. I'll take that with the chest and up kill power over the DS50's slower ADS with crouch up kill power.
I knew FMGs would be OP before the game came out: http://www.gamefaqs.com/boards/995751-call-of-duty-modern-warfare-3/59204323
