User blog comment:Dragonfly18/Additional Patch Notes for PS3/@comment-4630052-20120329234036

From what I've been hearing the PS3 players is that they totally changed eveything. They've done modifications to almost evey gun except for the M27 IAR, M4A1, and 870MCS.

The most affected guns were the FAMAS and AEK-971.

Another thing I've heard is that the USAS-12 is still the same...........
