{"product_id":"colt-field-repair-kit-m4-ar15","title":"Colt's Manufacturing Field Repair Kit – M4\/AR15","description":"\u003cp\u003eThis field repair kit provides the essential small parts most likely to break, wear out, or get lost during extended use of M4 and AR-15 pattern rifles. It's designed as a backup parts set for shooters who need to keep their rifle running in the field without access to a gunsmith or parts supplier. The kit covers common replacement needs: extractor components, gas rings, firing pin retaining pin, and other critical small parts that can fail under hard use or high round counts.\u003c\/p\u003e\u003cp\u003eAll parts are manufactured by Colt's Manufacturing to original specifications. The kit includes multiple gas rings, which wear gradually and should be replaced when compression weakens, plus a complete extractor spring and insert set. Most parts are drop-in replacements requiring only basic tools and familiarity with AR-15 disassembly. The extractor itself requires punching out the pin—straightforward for anyone comfortable with field stripping. Compact enough to store in a range bag or deployment kit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Field Repair Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e M4, AR-15 pattern rifles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Colt's Manufacturing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (basic disassembly knowledge required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas rings, extractor spring, extractor insert, firing pin retaining pin, and additional small parts per Colt specification\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Colt's Manufacturing","offers":[{"title":"Default Title","offer_id":47935997149439,"sku":"CTSPK403981","price":42.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5571449.jpg?v=1766482319","url":"https:\/\/doublestackstore.com\/products\/colt-field-repair-kit-m4-ar15","provider":"Double Stack Store","version":"1.0","type":"link"}
