The Browning Invector-DS Extended Full Choke Tube for 12 gauge shotguns brings real innovation to a part that's easy to overlook—until it gets stuck. The Double Seal design is the standout here: a brass alloy ring seats at the base of the tube to create an effective seal between the choke and barrel wall, keeping gas blowback and carbon residue from building up and locking things in place. After a heavy shooting day, you'll notice the difference when it comes time to strip and clean—these tubes stay significantly cleaner than conventional designs, which means easier maintenance and no stuck-choke frustration on the range or in the field.
The engineering behind the Invector-DS goes beyond the seal. A thin-wall construction paired with extended overall length creates longer parallel bearing surfaces inside the barrel, which translates to more consistent shot pattern performance. The flush-mount design keeps things compact and clean aesthetically, and the chrome-plated steel construction stands up to repeated use and the elements. Whether you're a waterfowl hunter running tight patterns, a competitive clay shooter cycling through different constrictions, or someone who simply values a choke tube that doesn't become a permanent fixture in your gun, the Invector-DS delivers.
This particular tube is the full choke constriction—the tightest standard option—designed for maximum shot density at distance. It pairs with any Browning shotgun featuring the Invector-DS system, and the engineering means it'll come out clean and easy every time.

The Invector-DS system is found on Browning shotguns equipped with this choke tube design. Check your gun's barrel markings or manual to confirm compatibility before purchase.
The brass alloy ring at the base creates a seal between the tube and barrel wall that prevents gas and residue from accumulating in the gap. This keeps the choke cleaner under use and makes it significantly easier to remove and maintain compared to conventional designs.
Full choke provides the tightest, densest shot pattern of the standard constrictions, making it ideal for longer-range shooting where you want maximum pattern density and consistency.
The Invector-DS is a flush-mount design, meaning it seats cleanly with the barrel muzzle when installed.
