Buff the M16A4s damage

Buff M16A4s damage by a little bit, because currently the DPS makes it a worse M4. The M16 is held by less people, which would be a good reason for it to at least have on par DPS with the M4. I suggest raising body shot damage by 1-2 and headshot by 3-4

I agree with this the M16A4 needs to be buffed a bit
