The Carlson's Choke Tubes 09205 Bismuth Bone Buster for Browning Invector-Plus 12 gauge is built for hunters who need reliable extended-range performance without compromise. Machined from 17-4 stainless steel, this choke tube is engineered to handle bismuth shot—a non-toxic alternative that delivers consistent patterns downrange. If you're running a Browning shotgun with Invector-Plus threading and want a durable, corrosion-resistant choke optimized for longer shots, this is a field-proven choice that won't let you down when it matters.
Bismuth ammunition has gained traction among waterfowl and upland hunters as a steel alternative that patterns tighter and carries energy farther. A dedicated bismuth choke tube like this one is designed around that ammunition's ballistics, giving you better shot distribution than running a standard choke with specialty loads. The 17-4 stainless construction handles the abuse of repeated use and exposure to the elements, so you're not buying a choke tube that'll corrode or fail mid-season.
Compatibility matters when you're swapping chokes in the field. The Invector-Plus system is found across Browning's shotgun lineup—A5s, Silver Series, Cynergy, and more—so verify your shotgun uses Invector-Plus threads before ordering. Once confirmed, this extended-range tube installs just like any other choke for that platform, giving you a focused point-of-impact tuned for bismuth shot performance.
