Extended Long Range Choke Tube for Your Bismuth Load

The Carlson's Bismuth Bone Buster choke tube is designed to produce excellent, dense patterns with Bismuth ammunition. It is CNC machined from 17-4 heat treated stainless steel and features a longer parallel section (inside the choke) than conventional factory choke tubes. Combine this with the extensive testing Carlson's has done with various loads and you have the best choke to deliver devastating patterns with Bismuth.

Bismuth Bone Buster Long Range choke tubes can also be used with steel shot not larger than #2.
