Carlsons Bismuth Bone Buster 12 Gauge Extended Range Choke Tube - Beretta/Benelli Mobil

The Carlson's Bismuth Bone Buster choke tube is designed to produce excellent, dense patterns with all bismuth non-toxic shot in your 12 Gauge shotgun. Rather than repurposing a conventional choke geometry, the Bone Buster is purpose-built around bismuth loads, with a longer parallel section inside the choke than a standard factory choke to keep the shot column under control for consistent pattern performance.

The tube is CNC precision machined from a single billet of 17-4 heat-treated stainless steel and ships as a single Extended Range choke with a .040" constriction. It is cut for the Beretta/Benelli Mobil choke system, so it fits Beretta and Benelli shotguns that accept the MobilChoke thread pattern.
