Briley Browning Invector DS Plasma Shotgun Choke Tube

With an ever-increasing interest in lighter extended chokes in sporting clays, Briley has responded with the totally new Plasma Choke. Built with high-strength aluminum alloys, Briley manufactures the Plasma Choke to the same exacting tolerances as their steel chokes. Innovative internal geometry enhances performance, as well as structural integrity, to reduce the effect of pressure. A proprietary coating is applied to further strengthen the surface against impact and abrading. While aluminum expands and contracts more than steel during heating and cooling cycles, demanding field tests confirm it to remain stable, and perform well with sporting clay loads. Plasma Chokes are recommended for all shot except steel.
