Browning Invector-DS 12 Gauge Flush Choke Tube

Browning’s Invector-DS choke tubes feature a double seal design that maintains cleaner tubes and longer choke tapers optimized to specific percentages rather than dimension alone. The tube fits flush with the barrel end while maintaining a longer profile than competitor offerings. A proprietary differential banded gas seal prevents residue accumulation and facilitates straightforward removal and installation. An integrated spring suspension maintains seal integrity while permitting controlled expansion and gas management. Invector-DS tubes are designed exclusively for Browning shotguns marked for Invector-DS and are incompatible with shotguns displaying Invector-Plus or Standard Invector on the barrel(s).
