Yea, "Stopping Power" is the best in its class, with Juggernaut in a close second. M16 with red dot, plus stopping power equals instant death when shot.
I only have one custom class that uses UAV jammer, and that is my stealth class, but I never use the stealth class since I always go 1 for 1 in that, and with the M16 I get awesome numbers.
