Extended Invector-DS™ Choke Tubes

• Extends beyond end of barrel for easy removal and even tighter patterns
• 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 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
