The Invector DS choke tubes are the most innovative choke system to hit the market. Unique Double Seal design features a brass alloy ring around the base of the tube to effectively seal the area between the tube and the barrel wall against gas and residue that make the tube difficult to remove. The DS choke tubes remain significantly cleaner, even under heavy use, than other choke tubes. The thin wall configuration and longer overall length allows longer parallel surfaces for maximum shot pattern performance.
- Fits 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
