m4a1
The M4A1 is the weapon that lets you blast people in the face while staying hidden. It's perfect for sneaking around and taking out enemies without them even knowing you're there.
I used my M4A1 in silence mode and took out 3 enemies. They didn’t even know I was there.
I used the silencer and snuck up on them. They didn’t know I was there.
The M4A1 is the best weapon for CQB. I use it every time.
