Carlson's Bismuth Bone Buster 20G Choke Tube

Optimized for Bismuth Performance

The Carlson's Bismuth Bone Buster choke tube represents a thoughtful engineering solution for shooters who rely on bismuth ammunition. Unlike standard factory choke tubes, this design features an extended parallel section that works in harmony with bismuth pellets to produce the dense, consistent patterns serious hunters demand.

Superior Construction

17-4 heat-treated stainless steel ensures durability and corrosion resistance through seasons of use. CNC precision machining guarantees exact tolerances and reliable performance every time you mount the tube.

Versatile Performance

While engineered specifically for bismuth loads, this mid-range choke tube performs excellently with:

• Bismuth ammunition
• Traditional lead shot
• Hevi-Shot loads
• Steel shot

The Right Tool for the Job

Extensive testing with various ammunition loads informed every aspect of this design. The mid-range constriction delivers the bone-crushing pattern density that separates clean harvests from frustrating misses. If you shoot bismuth, this choke tube deserves a place in your shotgun.
