Johnny Stewart Biz Raptor Invector Plus 12 Gauge Choke Tube - 17-4 PH Stainless Steel

The Johnny Stewart Biz Raptor Invector Plus is a precision 12 Gauge choke tube built for shooters who demand consistent, dense shot patterns from a Browning Invector Plus threaded barrel. Designed by Rob Roberts Gun Works and badged under the Johnny Stewart performance line, the Raptor series is engineered for pattern uniformity and reliable downrange performance on waterfowl, upland, and clay targets alike.

The Biz constriction sits within the Raptor family and is machined from American-made 17-4 PH stainless steel, delivering the tight, even distribution of shot that hunters and competitive shooters look for when patterning their shotgun. The 17-4 PH construction offers excellent corrosion resistance and the durability needed to hold its constriction shot after shot, season after season, with full compatibility with lead and steel shot loads.

Whether you shoot a Browning, Winchester, or any other shotgun factory-choked for Invector Plus threads, the Johnny Stewart Raptor series by Rob Roberts Gun Works offers the pattern consistency and long service life expected from a premium American-made choke tube. Stainless steel construction stands up to weather and heavy use in the field or on the range.
