It delivers reduced mass without compromising strength, durability, or reliability, making it ideal for fast, smooth, competition-ready AR-15 platforms. At just 8.5 ounces complete, this BCG reduces reciprocating mass to improve cycling speed, reduce recoil impulse, and enable faster follow-up shots. Faxon achieves this through careful geometry and an optimized cam path, maintaining critical material strength.\u003c\/p\u003e\u003cp\u003eAll components are salt bath nitrided to increase surface hardness, reduce friction, and provide excellent corrosion resistance. The carrier body receives Faxon's proprietary Superfinish to further reduce fouling and enhance smoothness of operation. Faxon recommends using an adjustable gas block to properly tune gas flow and ensure optimal function.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eKey Features\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eWeight:\u003c\/b\u003e 8.5 oz complete\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaterial:\u003c\/b\u003e 9310 Tool Steel Bolt\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFinish:\u003c\/b\u003e Salt Bath Nitrided Bolt \u0026amp; Carrier\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eSuperfinished Carrier Body\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eMagnetic Particle Inspection (MPI)\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eFull MIL-SPEC Heat Treatment \u0026amp; Shot Peening\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eBack of Lugs Chamfered for Reliable Cycling\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eExtractor:\u003c\/b\u003e S7\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eSpring, Insert, \u0026amp; \"Crane\" O-Ring Installed\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eGrade 8 Gas Key Fasteners, Fully Staked\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCompatibility:\u003c\/b\u003e M16 Pattern – Full Auto Compatible\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eFRT\/FRS Compatible\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCaliber Compatibility:\u003c\/b\u003e .300 BLK \/ 300 Blackout\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eForward Assist Serrations\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eLaser-Engraved Faxon Shield (post-QC)\u003c\/b\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eType:\u003c\/b\u003e Bolt Carrier Group\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePlatform:\u003c\/b\u003e AR15\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCaliber:\u003c\/b\u003e 5.56 NATO\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eColor:\u003c\/b\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCompatible Calibers:\u003c\/b\u003e 5.56 NATO, .223 Wylde, .300 BLK, 350 Legend\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Faxon Firearms","offers":[{"title":"Default Title","offer_id":47336202043481,"sku":"RSR-FXFF556BCGCNITRIDE-LW","price":266.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9860\/2329\/files\/faxon_RSR-FXFF556BCGCNITRIDE-LW-1.jpg?v=1791124230","url":"https:\/\/mountainready.online\/products\/faxon-5-56-gunner-lw-9310-bcg-ntrd","provider":"mountainready.online","version":"1.0","type":"link"}
