Specifically engineered for the unique ballistics of bismuth shot, this choke is designed to produce excellent, dense, consistent patterns at medium ranges, making it an excellent choice for waterfowl hunters and shotgunners running non-toxic loads.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eMachined from \u003cstrong\u003e17-4 heat-treated stainless steel\u003c\/strong\u003e using CNC precision processes, the Bone Buster features a \u003cstrong\u003elonger parallel section inside the choke\u003c\/strong\u003e compared to conventional tubes. This extended parallel section helps shape tighter, more uniform patterns with bismuth pellets, which behave differently than traditional lead shot. The result is improved pattern density and energy retention on target.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThis model is configured for \u003cstrong\u003eBeretta and Benelli MobilChoke\u003c\/strong\u003e systems, making it a direct drop-in replacement for factory choke tubes on compatible \u003cstrong\u003e20 gauge\u003c\/strong\u003e shotguns. It carries a \u003cstrong\u003eMid-Range constriction of .025\"\u003c\/strong\u003e, well suited for medium-range waterfowl and upland applications where a balance of pattern spread and downrange energy is needed.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eLike all Carlson's choke tubes, the Bismuth Bone Buster is engineered for years of reliable service in the field. \u003cstrong\u003eOne choke tube\u003c\/strong\u003e is included.\u003c\/span\u003e\u003c\/p\u003e","brand":"Carlsons","offers":[{"title":"Default Title","offer_id":55000154440002,"sku":"139361","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_f0c06686-d887-48eb-ae60-912eb9d75cc8.png?v=1784402571","url":"https:\/\/centerfiresystems.com\/products\/carlsons-bismuth-bone-buster-20-gauge-mobilchoke-025-mid-range-choke-tube-beretta-benelli","provider":"Centerfire Systems","version":"1.0","type":"link"}
