Almost certain it's bridged. Haven't really been interested in airsoft from mid November through the whole of December. Had no money to put down for the AA unit, so had nothing to do. But now, I've got enough to get the AA unit. So the running version will be: stock vsr barrel (bridged), VSR bucking, AA unit.
Yeah. Certain buckings require barrels (bridge/non bridge). before, I was getting way too confused.. I think I started adding the AA unit into the mix, and thought that would only require a certain type of bucking/barrel..
