BRN 113-4273 CHK TUBE 12 MD EXT INV DS

Extended Invector DS Choke Tubes have the Proprietary deferential banded gas seal that eliminates residue build up and makes chokes easy to remove and install. The Integrated spring suspension holds the seal tight, yet allows expansion against the barrel wall for a perfect fit and a smooth transition from shot column entering choke gas is controlled at the interface between choke and where it seats in the bore. From skeet to full choke, patterns tighten consistently and reliably. Invector-DS tubes fit only Browning shotguns designed for Invector-DS and are not for use in shotguns showing Invector-Plus or Standard Invector on the barrel(s).
