Rob Roberts Gun Works Biz Raptor Invector 20 Gauge Stainless Choke Tube

Rob Roberts Gun Works Biz Features The Rob Roberts Gun Works Biz choke tube is engineered specifically around bismuth shot one of the most widely used non-toxic shot materials in waterfowl and upland hunting today. Pairing the Biz choke with bismuth loads lets shooters get the most consistent patterns that shot type can deliver which matters when a clean ethical shot is the goal. Built from 17-4 PH U.S. stainless steel the choke resists corrosion and wear from repeated use in the field and across a range of weather conditions. The Invector thread pattern makes it a direct fit for shotguns built around that choke system so installation is straightforward for any owner comfortable swapping chokes. Every RRaptor Series choke including the Biz is the product of years of development and advanced manufacturing processes meant to maximize pattern density and shot performance. The precision machining behind the 17-4 PH stainless construction gives the choke the strength to handle sustained use without degrading its internal geometry. Shooters running an over and under shotgun should note that only one barrel can carry an RRaptor choke at a time since the design does not allow placement in both barrels simultaneously. For 20 gauge shooters who want a dedicated bismuth choke built to a high manufacturing standard the Rob Roberts Gun Works Biz Raptor is available for sale at ARMSAGORA.
