Browning Invector-DS 12 Gauge Modified Extended Choke Tube, Chrome - 1134273

This is an extended choke tube designed for 12 gauge shotguns with Invector-DS compatible barrels. Constructed from stainless steel with a chrome finish, it features Browning's innovative Double Seal design with a brass alloy ring that seals against the barrel wall to prevent gas leakage and residue buildup. The thin wall configuration and extended length provide maximum shot pattern density, with a .020" modified constriction suitable for shooting distances up to 45 yards.
