i've been doing alot of sniping lately, even though I've never been much of a sniper on fps games.

using :

WA2000 + FMJ+Heartbeat Sensor
Spas + Grip + Extended Mags
Bling
Cold Blooded
Steady Aim

I'm only using bling because I like having the heartbeat sensor and I'm trying to unlock extended magazines... and not doing very good at that. 9/40 penetration kills w\ FMJ and I really don't think I even got 1 penetration kill in 6-7 straight games last night!
