A 12 gauge shotgun with changeable choke tubes that fires 3.5" shells.
Either Invector or Invector+ depending on how it left the factory.
I don't think there is an invector plus model. Invector Plus is the choke system Browning uses on newer shotguns.
Browning did not make an Invector model. That is the type choke system of the shotgun.
Browning's web site has the current information.
You will have to call Browning to find out.
