The Stoner is such a beastly gun. It sucked on the early leveling up grind, but without purposely going for the gold camo and only really playing objective game modes, it got me a 2 K/D average over 1000 kills. I'm not some major COD boy either.
Its my fave, I love the M60 also cause of how hard it hits, but the Stoner has crazy good accuracy even on full auto. It makes you slow as shit and the aim time is slow, but once you are down the sights, its a shredder
