Invector-Plus™ choke system. The proven Invector-Plus interchangeable choke tube system works hand-in-hand with Vector Pro and back-boring to offer consistent, dense shot patterns with just the constriction needed for the shooting situation. The longer choke taper inside an Invector-Plus choke tube produces consistent patterns with more uniform densities and fewer fliers. The superior design of the Invector-Plus system is far more durable than the choke systems found in our competitors’ guns, especially when shooting steel shot. Invector-Plus eliminates gases slipping between the choke tube and barrel that could damage the choke tube and the barrel.
Shown left is a full range of Invector-Plus extended choke tubes. Browning shotguns with Invector-Plus are supplied with a variety of choke selections and configurations depending on the model. Most Browning's with Invector-Plus feature flush mounted versions in various finishes (shown at right). Extended tubes like those shown leftare standard on some models and are also available as accessory items from Browning.
