I've pretty much gone to the SVU in place of the M14, since the M14 doesn't appear to kill anybody now

On that note, I know the M14 is for all classes and SVU only for recon. But, being it's semi-auto and I love having the silencer, recon ball and mortar strike or C4 if necessary.
The BA rifles, well I only used the M24, but haven't been able to kill anybody with that either. I used Arica Harbor as my recon boost level from the beginning, now (past 10 days), I'm lucky to get one kill if I use it and it makes me really mad. It seems no matter who or where, I can't get the kill. The same for all the other BA's. I've never been good with the M95 and the Gol, while accurate seems to not have power, so I don't get kills with it. I know I could use Magnum Ammo, but to me that's counter productive to my team if I'm going to play hide-and-spot.
Now, I'd rather use SVU or VSS, run with my team and still have spotter scope (sometimes Mag Ammo)
