Precision 17-4 stainless steel choke tube optimized for bismuth ammunition. Extended range design produces dense, devastating patterns. Compatible with lead, bismuth, and steel shot.
The Carlson's Bismuth Bone Buster is a precision-engineered choke tube designed specifically to maximize the performance of bismuth ammunition. Built from 17-4 heat-treated stainless steel and manufactured using CNC precision machining, this choke delivers the dense, consistent patterns that modern waterfowl and upland hunters demand.
Extensive testing with various loads ensures this choke tube delivers the bone-crushing dense patterns that separate successful hunts from missed opportunities. The longer parallel section concentrates shot more effectively than standard factory chokes, giving you tighter, more uniform patterns downrange.
Fits Remington Rem Choke shotguns in 20-gauge. Drop-in installation—no gunsmithing required.
