Pretty awesome gun.
This gun is an awesome and my second favorite gun, I've been using it online since I was at level 29, now I am at Prestige level 2 level 30, this and the Ballistic Knives are really good together.
Ak74U+Warlord perk+Rapid fire+grip.( epic!!)
I would suggest Hacker (because you'll be running around a lot) and Scavenger.
Trust me this is an awesome gun( not recommended for snipers and stealth players, campers not included)
