Scar-H, just started using it, I love it, it's perfectly balanced too, almost nothing can stop it at long range except it's recoil and accuracy, at short ranges unless you have a whole second head start it's hard to get a kill, and at medium ranges it has a big advantage. With a couple o' attachments like grip and quickdraw, this easily becomes the most powerful gun in the game yet it's still not overtaking those close ranged fights with an94s,
Gotta say, we need more guns like this, more, balanced guns. Seriously.
