More than halfway to 2nd prestige.
I used the M16 for most of my first prestige, it's very accurate and great at medium-long range. Frustration with close range is the only reason I use the Galil instead. Regardless of which gun I use, my secondary is the crossbow or nothing. I'm awesome with the crossbow.
My attachments are dual mag and suppressor. Dual mag is pretty much a standard attachment for any gun that has it, and I go with suppressor because I don't mind iron sights and it's helpful to avoid radar pings. My perks are Hardline Pro, Warlord Pro, and Ninja Pro. I rarely change these. Because of spawn issues(most notably on nuketown), I stick to objective-based games, mostly demolition. Since I play demolition a lot, my killstreaks are SAM, care package, and mortar team. SAM is incredibly useful, and hardline pro means that if I already have a SAM up I can change the package to something else. Mortar team is pretty useful on most maps with demolition or domination.
