Browning Invector DS choke tubes use a revolutionary double seal that keeps tubes clean longer, and longer choke tapers that optimized patterns for percentages, not just dimensions. These are flush fit tubes, but are longer than competitors, with a design that eliminates residue build-up, making tubes easier to remove and install. Available from skeet to full choke, they produce patterns that tighten consistently and reliably.

This is a single choke tube.
