Johnny Stewart Raptor RR3 20 Gauge Invector 17-4 PH Stainless Steel Choke Tube

The Johnny Stewart Raptor RR3 is a long-range choke tube produced by Rob Roberts Gun Works for waterfowl hunters running 20 Gauge shotguns fitted with the Invector choke system. Built to deliver tight, hard-hitting patterns at extended distances, the RR3 is engineered specifically for geese and open water ducks, providing the dense constriction needed for those long-crossing shots.

Precision-machined from 17-4 PH stainless steel, the same U.S. stainless alloy used in premium choke construction for its corrosion resistance and ability to hold pattern tolerances under heavy use, the RR3 installs in any 20 Gauge barrel threaded for the standard Invector pattern. The tube measures 7.5 inches overall and is part of the Raptor long-range choke series, giving 20 Gauge waterfowl shooters a dedicated long-range constriction for big-water hunting.
