Invector Plus choke tubes come standard in all Browning back-bored barrels. Invector Plus and back-boring work together as a team. The longer choke taper inside an Invector Plus choke tube - combined with back-boring - produces patterns with uniform densities. Invector Plus tubes are for Browning's back-bored 20 gauge shotguns only, and are not intended for standard bored barrels.
- For use in Browning back-bored Invector Plus barrels only. Do not use in standard Invector barrels
- Browning has changed finish from Black Oxide to Stainless Steel
