Next generation Browning Invector-DS choke tubes sit flush with the end of the barrel, and are significantly longer than most competitors. They have a revolutionary double seal that controls gas at the interface between choke and barrel, that keeps things cleaner, eliminates residue, and makes chokes easy to remove and install. They produce consistent, reliable pattern tightening.
