Browning 20 Gauge Extended Choke Tube Browning Invector-DS Modified

Browning has been a leader in interchangeable choke tubes systems since the 1980's. They offer three systems: 1) the legacy Standard Invector, 2) the time-proven Invector-Plus system, and 3) the extreme-performing new Invector-DS system. An extensive selection of tubes in each system provides you with optimal patterns. It is worth the effort to find the right tube. In order to do that, simply select the Browning choke system which your shotgun is designed to accept, and then choose the constriction and design for your system and gauge.
