BROWNING 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
