Browning Invector-DS 12 Gauge Full Choke Tube Accessory

Browning’s Invector-DS choke tubes feature a double seal design that minimizes residue accumulation in the barrel. The extended choke tapers are calibrated to specific shot pattern percentages rather than dimension alone. A proprietary differential banded gas seal prevents buildup and facilitates straightforward removal and installation. An integrated spring suspension mechanism maintains seal pressure while accommodating expansion and regulating gas flow. Note: Invector-DS tubes are compatible only with Browning shotguns marked for Invector-DS and cannot be used in shotguns labeled Invector-Plus or Standard Invector.
