The Carlsons Bismuth Bone Buster Rem Choke is a 12 Gauge extended-range choke tube machined for shooters using bismuth and other non-toxic shot. It is CNC precision machined from heat-treated 17-4 stainless steel and features a longer internal parallel section compared with conventional factory choke tubes to help produce dense patterns. The tube is configured for Rem-style (Rem Choke) installations and is compatible with a range of non-toxic and traditional loads.
