Thats been in there a long time. New guns are the ParaFNFAL or w/e, Toygun, P90TR CBS, Jackhammer.
FNFAL - AR
Toygun - AR (most likely)
P90TR CBS - P90TR with a bad red camo
Jackhammer - check EU for gameplay, there some videos of it being in CANA, but the gun itself is unreleased here, and to me, its a beefy M4S90 in sound, 1/2 hit close range, 3-100000 hits in medium/long range.
My info? Youtube, some guy got his video featured, and mpgh xD
The P90TR CBS was just a promotion for some german magazine in CAEU
