Made from Case-hardened 8620 steel.\u003c\/p\u003e\u003cp\u003eThe CMC enhanced carrier has fewer points of contact resulting in less friction area. The increase in mass ensures proper gas pressure and increases dwell time thus improving extraction while shooting suppressed or short-barreled rifles (SBRs). Bolt Assembly: The Bolt is a “true” Mil-spec dimension. The external surfaces are CNC ground after heat treatment for a precision fit. The bolts are held to the highest possible tolerances. The “trumpet” area behind the gas rings where carbon collects is precision CNC Ground after heat treatment to ensure as smooth of an area as possible easing clean up and longevity. Made from 9310 Case Hardened Steel bolt components are Shot Peened \u0026amp; Black Nitride coated.\u003c\/p\u003e\u003cul\u003e\t\u003cli\u003eBlack Nitride finish\u003c\/li\u003e\t\u003cli\u003eEnlarged forward ports\u003c\/li\u003e\t\u003cli\u003eOptimized for suppressor use\u003c\/li\u003e\t\u003cli\u003eHardened 4340 cam pin\u003c\/li\u003e\t\u003cli\u003eMil-Spec 8740 steel firing pin\u003c\/li\u003e\t\u003cli\u003eMPI and HPT tested\u003c\/li\u003e\t\u003cli\u003eMil-Spec Extractor Spring \u0026amp; O-Ring\u003c\/li\u003e\t\u003cli\u003e.223\/5.56\/300BLK compatible\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003eBolt Carriers\u003cbr\u003e81631","brand":"Cmc Triggers","offers":[{"title":"Retail","offer_id":45131906416777,"sku":"UT81631","price":179.1,"currency_code":"USD","in_stock":true},{"title":"Member","offer_id":45131907530889,"sku":"UT81631","price":147.39,"currency_code":"USD","in_stock":true},{"title":"Premium Member","offer_id":45131907563657,"sku":"UT81631","price":140.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0659\/2813\/4793\/files\/UT81631.jpg?v=1767638339","url":"https:\/\/christianvigilant.com\/products\/cmc-triggers-cmc-enhanced-bolt-carrier-group-ar-15-5-56-223-300-blackout","provider":"Christian Vigilant","version":"1.0","type":"link"}
