Built with a Type 2 bolt face and machined to precise Mil-Spec dimensions, this bolt carrier group features a case-hardened 9310 steel bolt and a case-hardened 8620 steel carrier, both treated with a Black Nitride finish across all metal surfaces. This advanced low-friction coating dramatically reduces the need for lubricants, helping keep your rifle running cleaner and more reliably in demanding conditions. The gas key is machined from 4130 steel, attached with Grade 8 hardware, and properly staked into a milled valley to guarantee precise positioning and long-term retention. Every bolt has been Magnetic Particle Inspected (MPI) and High Pressure Tested (HPT) to ensure quality and safety before it leaves the factory.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlack Nitride Finish on All Components:\u003c\/strong\u003e Advanced low-friction coating minimizes lubrication requirements and resists fouling for sustained reliability.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMil-Spec Dimensions Throughout:\u003c\/strong\u003e Type 2 bolt face with CNC-ground external surfaces after heat treat for a precision fit in AR-15 and M4 compatible rifles.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePremium Steel Construction:\u003c\/strong\u003e Carrier machined from case-hardened 8620 steel; bolt machined from case-hardened 9310 steel for superior strength and durability.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPI and HPT Certified:\u003c\/strong\u003e Each bolt is Magnetic Particle Inspected and High Pressure Tested for verified quality and reliable function.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-Quality Sub-Components:\u003c\/strong\u003e Includes a hardened 4340 steel cam pin, Mil-Spec 8740 steel firing pin (centerless ground and Hard Chrome coated), and a 4340 steel Mil-Spec extractor with O-ring combination.\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 ODIN Works\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e ACC-223-BCG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 856205005827\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Platforms:\u003c\/strong\u003e AR-15, M4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Calibers:\u003c\/strong\u003e .223 Remington \/ 5.56 NATO, .300 Blackout\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarrier Material:\u003c\/strong\u003e Case Hardened 8620 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Material:\u003c\/strong\u003e Case Hardened 9310 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Key Material:\u003c\/strong\u003e 4130 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Key Hardware:\u003c\/strong\u003e Grade 8, properly staked into milled valley\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCam Pin:\u003c\/strong\u003e Hardened 4340 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFiring Pin:\u003c\/strong\u003e Mil-Spec 8740 Steel, centerless ground, Hard Chrome coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtractor:\u003c\/strong\u003e 4340 Steel Mil-Spec with O-Ring combination\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Nitride (all components)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Face Type:\u003c\/strong\u003e Type 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarrier Type:\u003c\/strong\u003e M16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInspection:\u003c\/strong\u003e Magnetic Particle Inspected (MPI), High Pressure Tested (HPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New\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.
