Did you know....? That you didn't buy the game for'em and they can use whatever it is they wanna use? 98% of the community needs to stop crying about "what killed them".
If it takes you more then half of your pdw clip to kill 1 person, I think you should stick with that gun.
Yeah, it's the 50 round clip...saves you a point for something else. I've been using the MP7 alot more than any other gun, it looks better than the diamond PDW and 10 less bullets isn't a big deal. I don't use any other attachment than the silencer, 40 bullets can go a long way if you're accurate.
I stopped using it when I maxed it and got the gold camo for it. There are so many better guns than this one. I blame Youtubers and Twitchers.
