The Johnny Stewart Rob Roberts Gun Works 200308 Biz Raptor Mobil 12 Gauge 17-4 PH Stainless Steel choke tube is purpose-built to deliver consistent patterns with modern bismuth shot shells. Crafted from durable 17-4 PH U.S. stainless steel, it combines a black BIZ-marked extension with a Mobil-pattern threaded body for reliable installation on compatible 12 gauge shotguns.

This Biz Raptor Mobil choke is designed as a mid-range constriction, ideal for waterfowl and general hunting where bismuth loads are preferred. Due to its internal design, over-under shotguns can accept the RRaptor choke in only one barrel, making it a specialized option for shooters who demand predictable performance from a single tube. The choke reflects years of product development and innovation from Rob Roberts Gun Works and Johnny Stewart.
