I read the patch notes that there was a nerf to a few of the key meta weapons in the game. So, I went ahead and tested them for myself. I thought I would share what I found for anybody else who is curious. Again, this is hand tested so there is always a margin of error with it. But, here is the lowdown. Also, note the crossbows thermite bolts were nerfed against score streaks, but the patch notes explains that very clearly and in full.
MP5:
The 10mm rounds lost 2 meters off their 3 shot kill range. So, they really aren't worth using over the standard 9mm ammo now. Also, the weapon now requires one additional head shot at all ranges in order to save you a bullet to kill. So, it cannot get a 2 shot kill with 2 head shots up close. Likewise, it will take 2 head shots to get a 3 shot kill in the 4 shot range and so on. This makes the bison, Uzi and AUG all more productive weapons if you are good at getting head shots. But, otherwise the weapon isn't overly affected.
M4A1:
The M4 got kicked, but not pummeled with this nerf. The weapon now requires 2 head shots in order to save you a bullet to kill in the 4 and 5 shot range. One head shot still help in the 6 shot range, additionally, the 4 shot kill range was reduced by 3 meters. Note, these changes only affect the 556 ammo. The Socom and 9mm conversions are not affected by these nerfs at all. This doesn't dethrone the M4, but it does hurt it. So, you may want to try out the Kilo, M13 or Ram7 if you are unhappy with this alteration.
M13:
The M13 got a pretty healthy buff. First, the 5 shot kill range got pushed out by 6 meters. Secondly the horizontal recoil got noticeable reduction making this weapon easier to control at longer ranges. The 5 shot kill range buff seems significant, but there isn't all that big a difference between a 5 and 6 shot kill on a weapon that fires at over 900 RPM. But this recoil change is very noticeable. This make the M13 a much more competitive gun at midrange and it's definitely worth considering after this buff. Give it a shot if you haven't already.
That about wraps up the alterations with this update. Happing gaming and let's look forwards to season 2 in a few weeks.

m13 뭔가 반동상향 체감때문인지 중거리 괜찮더라
4발컷구간 감소는 좀 ㄱㅊ네
