Carlsons Bismuth Bone Buster Invector Plus 12 Gauge Mid-Range Choke Tube - .025

The Carlsons Bismuth Bone Buster choke tube is purpose-built for hunters running bismuth shot loads through a 12 gauge shotgun fitted with the Browning Invector Plus choke system. Designed to wring dense, consistent patterns out of bismuth pellets, this Mid-Range choke is CNC precision machined from 17-4 heat-treated stainless steel for outstanding corrosion resistance and a long service life in the field.

At its core, the Bismuth Bone Buster delivers a .025" constriction that sits in the middle of the spectrum. A longer parallel section inside the choke works with bismuth's unique ballistics to keep pellets on target at range rather than spreading them thin.

This choke is a drop-in upgrade over factory tubes for Browning Invector Plus 12 gauge shotguns. One choke tube is included.
