Carlsons Bismuth Bone Buster 12 Gauge Rem Choke Extended Range .040 17-4 Stainless Choke Tube

The Carlsons Bismuth Bone Buster choke tube is purpose-built for waterfowl hunters running bismuth shot loads in modern Remington Rem Choke-equipped 12 Gauge shotguns. Designed to produce tight, dense patterns with bismuth ammunition, this Extended Range choke delivers the constriction and shot-string control needed at longer crossing distances on ducks and geese.

CNC precision machined from 17-4 heat-treated stainless steel, the Bismuth Bone Buster features a longer parallel section inside the choke compared to conventional factory chokes, keeping the shot column aligned for more uniform downrange patterns. The .040 in constriction slots in as an Extended Range tube in your Remington Rem Choke barrel with no gunsmithing required, and the corrosion-resistant 17-4 PH stainless steel construction holds up to the abuse of a full waterfowl season.

This listing is for a single choke tube (one Bismuth Bone Buster), proudly made in the USA and backed by Carlsons' lifetime warranty, so you can focus on filling bag limits instead of worrying about your gear.
