Carlsons Bismuth Bone Buster 20 Gauge Beretta Optima HP Extended Range .040 Choke Tube

The Carlsons Bismuth Bone Buster choke tube is purpose-built to deliver dense, consistent patterns with bismuth shot in 20 Gauge shotguns. Designed for the Beretta Optima HP choke system, this Extended Range tube carries a .040 constriction and is CNC precision-machined from 17-4 heat-treated stainless steel for outstanding durability and corrosion resistance.

The Bone Buster series features a longer parallel section inside the choke compared to conventional factory choke tubes, helping to shape tighter, more uniform patterns at longer ranges. It is engineered to produce excellent, dense patterns with all bismuth loads and can also be used with all steel shot not larger than #2, making it a versatile pick for waterfowl and upland hunters running bismuth or steel shot through their Beretta Optima HP-equipped 20 gauge shotguns.

Built from 17-4 stainless steel with precision CNC machining, this choke is a direct-fit replacement that installs easily in the Beretta Optima HP threads. One choke tube is included.
