Rob Roberts Gun Works BIZ Raptor 12 Gauge Choke Tube – 17-4 PH Stainless Steel for Bismuth Shot

The Rob Roberts Gun Works BIZ Raptor Choke Tube (Model 200308) is purpose-built for use with bismuth shot loads in 12 gauge shotguns, delivering consistent, optimized performance that standard choke tubes simply can’t match. Engineered as part of the acclaimed RRaptor Series, this choke tube is the product of years of dedicated research, development, and innovation using the most advanced manufacturing technology available.

Constructed from premium 17-4 PH U.S. Stainless Steel, the BIZ Raptor offers exceptional strength, corrosion resistance, and long-term durability — qualities that matter whether you’re in the field or on the range. Bismuth shot is increasingly popular among waterfowl hunters and shooters who require a non-toxic, dense shot option, and the BIZ Raptor is specifically designed to complement its unique ballistic characteristics for tighter, more predictable patterns.

Please note: For over/under shotguns, the RRaptor choke tube can only be installed in one barrel at a time. The design of the choke does not permit simultaneous placement in both barrels.

Whether you’re a waterfowl hunter making the switch to bismuth or a competitive shooter optimizing your setup, the Rob Roberts Gun Works BIZ Raptor is a smart, high-quality upgrade to your shotgun’s performance.
