I bought a browning 12ga pump shotgun at a pawn shop. The barrel reads invector plus bps special steel 12ga 2 3/4 and 3" field model 30". I also got another barrel with it that reads bps special steel 12ga 2 3/4 and 3" deer special model 22". I paid $500 for all. I haven't been able to find much on the net so I turn here for help. Did I get taken? Thanks
