The Browning 20 Gauge Invector-DS Choke tubes are a revolution in choke design. The double seal keeps tubes cleaner. Longer choke tapers are optimized to percentages, not dimension only.
Fits shotguns made for 20 gauge Invector-DS only. Choose from a full selection of constrictions.
- 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 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
