Carlsons Bismuth Bone Buster Retay 12 Gauge Extended Range 17-4 Stainless Steel Choke Tube

The Carlsons Bismuth Bone Buster choke tube is purpose-built to unlock the performance of bismuth shotgun shells, producing dense, even patterns that put the maximum payload on waterfowl and long-range targets. This specific model is configured for Retay shotguns in 12 Gauge and is CNC-machined to Extended Range specifications with a .040 constriction.

Constructed from 17-4 heat-treated stainless steel, the Bone Buster features a longer parallel section inside the choke than a conventional factory tube. That added parallel length tightens and stabilizes the shot column, which is critical for getting the most out of bismuth loads and their softer-than-steel pellets. The stainless steel body shrugs off corrosion, making it right at home in wet marsh and late-season duck and goose hunting conditions.

Carlsons machines every Bismuth Bone Buster choke in the USA and stands behind it with a lifetime warranty, giving hunters a purpose-tuned tube for premium bismuth ammunition. This listing includes one choke tube.
