Invector-DS™ Choke Tubes

• Fit flush with the end of the barrel but are longer than competitors’ tubes
• Proprietary differential banded gas seal eliminates residue build up and makes chokes easy to remove and install
• Integrated spring suspension holds the seal tight, yet allows expansion against the barrel wall for a perfect fit and a smooth transition for the shot column entering the 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 chokes will only fit shotguns that are threaded to accept them. They are not compatible with Invector-Plus or the Standard Invector choke system.
