Going beyond typical MIL-SPEC baselines, it features a Type II (.136\") bolt machined from 9310 tool steel, then fully heat treated, shot peened, and magnetic particle inspected (MPI) to help ensure durability and material integrity. A salt bath nitride treatment on both the bolt and carrier increases surface hardness, reduces friction, and improves corrosion resistance, while the carrier body is superfinished for easier cleaning and consistent operation. Chamfered bolt lugs and a quality extractor system (S7 extractor with spring\/insert and “Crane” O-ring installed) support dependable function across demanding conditions.\u003c\/p\u003e\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eType II (.136\") bolt designed for 6.5 Grendel and compatible Grendel\/ARC bolt-face platforms\u003c\/li\u003e\n  \u003cli\u003e9310 tool steel bolt with full MIL-SPEC heat treatment, shot peening, and MPI testing\u003c\/li\u003e\n  \u003cli\u003eSalt bath nitride finish on bolt and carrier for hardness, low friction, and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eSuperfinished carrier body helps reduce fouling and promotes smoother cycling\u003c\/li\u003e\n  \u003cli\u003eReliability-focused details including chamfered lugs, S7 extractor, and installed “Crane” O-ring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Bolt Carrier Group (BCG)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform\u003c\/strong\u003e: AR-15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber \/ Compatibility\u003c\/strong\u003e: 6.5 Grendel; also compatible with 6mm ARC, 22 ARC, and 338 ARC (Grendel\/ARC bolt-face family)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Type\u003c\/strong\u003e: Type II, .136\" bolt face depth\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\u003c\/strong\u003e: S7 extractor; spring\/insert and “Crane” O-ring installed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTesting\u003c\/strong\u003e: Magnetic Particle Inspection (MPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Treat \/ Surface Prep\u003c\/strong\u003e: Full MIL-SPEC heat treatment; shot peened\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLug Geometry\u003c\/strong\u003e: Back of lugs chamfered for reliability\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Salt bath nitride (bolt \u0026amp; carrier)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarrier Details\u003c\/strong\u003e: Superfinished carrier body; M16-pattern (full-auto compatible); forward assist serrations; grade 8 gas key fasteners, fully staked\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNot Compatible With\u003c\/strong\u003e: Faxon 7.62x39 barrels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 816341024168\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FF65GBCGCNITRIDE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Faxon Firearms\u003c\/li\u003e\n\u003c\/ul\u003e\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.
