Faxon treats MIL-SPEC as a baseline, enhancing key wear surfaces and critical components for long-term reliability. The bolt is made from 9310 tool steel, fully heat treated, shot peened, and Magnetic Particle Inspected (MPI) to help ensure material integrity. The bolt and carrier are salt bath nitrided to increase surface hardness and improve corrosion resistance, while the carrier and gas key feature a color-shifting Chameleon PVD coating for added wear resistance and a distinctive finish.\u003c\/p\u003e\n\u003cp\u003eReliability-focused details include chamfered bolt lugs for consistent cycling, an S7 extractor, and a spring\/insert\/“Crane” O-ring installed. As an M16-pattern carrier, it is full-auto compatible, making it a strong choice for duty rifles, training carbines, and high-round-count setups where durability and ease of maintenance matter.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e9310 tool steel bolt with MIL-SPEC heat treatment, shot peening, and MPI testing for confidence in critical parts\u003c\/li\u003e\n  \u003cli\u003eSalt bath nitride treatment on bolt and carrier enhances surface hardness and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eChameleon PVD coated carrier and gas key deliver a unique color-shifting finish with added wear resistance\u003c\/li\u003e\n  \u003cli\u003eChamfered bolt lugs plus extractor spring\/insert\/“Crane” O-ring installed to support reliable cycling\u003c\/li\u003e\n  \u003cli\u003eM16-pattern, full-auto compatible carrier design for AR-15\/M16 platforms\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Faxon Firearms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Bolt Carrier Group (BCG)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform Compatibility:\u003c\/strong\u003e AR-15 \/ M16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 5.56 NATO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarrier Pattern:\u003c\/strong\u003e M16 (full-auto compatible)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Material:\u003c\/strong\u003e 9310 tool steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtractor Material:\u003c\/strong\u003e S7 tool steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInspection:\u003c\/strong\u003e Magnetic Particle Inspection (MPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Treatment:\u003c\/strong\u003e Salt bath nitrided bolt \u0026amp; carrier\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating:\u003c\/strong\u003e Chameleon PVD coated carrier \u0026amp; gas key\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e FF556BCGCNITRIDE-NCR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 816341024649\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
