Best gun to use ??? oncod4

mp5 is weak, m4 i used to have but again is weak.
But m16 tbh! Or the first sniper rifle <3 lol

When your level 40, Use :
P90 SILENCED or p90 RED DOT
Increased Bullet Damage ( whichever perk does that )
Deeper Bullet Penetration
<3

I use the MP5 up until I unlock the P90.
Used to use the M4 but it appeared to have a lack of ammunition.
