The TriStar Cobra III Marine is a 12 Gauge pump-action shotgun with an 18.5″ barrel designed for reliable, versatile performance across light target loads and heavy waterfowl loads. This Marine-specific configuration features an assisted spring-loaded forearm that returns forward after cycling and can be removed to operate as a conventional pump. The barrel and chamber are chrome-lined for corrosion resistance, and the firearm uses the Beretta/Benelli Mobil removable choke system (one Cylinder choke included).
