Winchester 12 Gauge Choke Tube Browning Invector, Mossberg Accu-Choke, Win-Choke Modified

Invector Plus choke tubes are designed for optimum performance with Winchester's back-bored barrels. The longer choke taper inside an Invector Plus choke tube, combined with back-boring, produces patterns with uniform densities. For use in Browning or Winchester back-bored Invector Plus barrels only. Do not use in Invector barrels.
