Invectorplus Choke Tube System

Chokes Invector Plus

New model BT-99 shotguns feature a barrel fitted with the Invector-Plus choke tube system. Older BT-99s may also have the Standard Invector tube system or a conventionally choked barrel. The Invector-Plus system is a screw in choke tube system with interchangeable tubes. You can confirm this by reading the inscription on the right side of the barrel.
