Built around a forged Stressproof bolt made from Carpenter 158+ steel, this assembly is designed to deliver substantially greater fatigue resistance than standard mil-spec bolts. Each bolt is rigorously high-pressure tested, magnetic-particle inspected, and shot-peened for confidence under hard use. The included extractor is paired with Geissele's Nanoweapon coating, which helps reduce friction while enhancing wear and corrosion resistance for smooth, consistent function.\u003c\/p\u003e\u003ch3\u003eProduct Highlights\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eForged Carpenter 158+ Stressproof bolt designed for enhanced strength and extended service life\u003c\/li\u003e\n\u003cli\u003eIncludes extractor and related bolt components for a ready-to-install bolt assembly\u003c\/li\u003e\n\u003cli\u003eNanoweapon-coated bolt and extractor help reduce friction and improve corrosion and wear resistance\u003c\/li\u003e\n\u003cli\u003eHigh-pressure tested, magnetic-particle inspected, and shot-peened for dependable performance\u003c\/li\u003e\n\u003cli\u003eCompatible with AR-15 and M4 platforms chambered in .223 Remington, .223 Wylde, 5.56 NATO, and .300 Blackout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eProduct Type: Bolt Assembly\u003c\/li\u003e\n\u003cli\u003eBrand: Geissele Automatics\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number: 05-2991\u003c\/li\u003e\n\u003cli\u003eUPC: 810081134972\u003c\/li\u003e\n\u003cli\u003eBolt Material: Carpenter 158+ forged steel\u003c\/li\u003e\n\u003cli\u003eExtractor Material: 300M stainless steel\u003c\/li\u003e\n\u003cli\u003eFinish\/Coating: Nanoweapon coating\u003c\/li\u003e\n\u003cli\u003eTesting: High-pressure tested\u003c\/li\u003e\n\u003cli\u003eInspection: Magnetic-particle inspected\u003c\/li\u003e\n\u003cli\u003eAdditional Quality Control: Shot-peened\u003c\/li\u003e\n\u003cli\u003eIncludes: Bolt, extractor, extractor spring, O-ring insert, ejector, ejector spring, and pin\u003c\/li\u003e\n\u003cli\u003eCompatibility: AR-15 \/ M4 platforms chambered in .223 Remington, .223 Wylde, 5.56 NATO, and .300 Blackout\u003c\/li\u003e\n\u003cli\u003eWeight: Approximately 1.54 oz assembled\u003c\/li\u003e\n\u003c\/ul\u003e\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.
