{"product_id":"luth-ar-223-rifle-buffer-spring","title":"Luth-AR .223 Rifle Buffer Spring – AR-15 Pattern Rifles","description":"\u003cp\u003eThe Luth-AR .223 Rifle Buffer Spring is a direct replacement for worn or weakened factory buffer springs in AR-15 pattern rifles. Over time and use, buffer springs lose tension, leading to cycling issues, short-stroking, or failures to eject. Replacing your buffer spring as part of regular maintenance or troubleshooting cycling problems restores reliable function and proper bolt carrier group operation.\u003c\/p\u003e\u003cp\u003eManufactured from heat-treated chrome silicon wire, this spring is built to OEM specifications for consistent performance. It's a drop-in installation requiring no gunsmithing—simply remove the buffer retainer pin, extract the old spring and buffer, and install the new spring. Takes less than five minutes with basic tools.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Buffer Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 pattern rifles chambered in .223\/5.56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Chrome silicon wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e (1) Buffer spring\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Luth-AR","offers":[{"title":"Default Title","offer_id":47938428698879,"sku":"LUTHBS-10B","price":4.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1290112.jpg?v=1766514665","url":"https:\/\/doublestackstore.com\/products\/luth-ar-223-rifle-buffer-spring","provider":"Double Stack Store","version":"1.0","type":"link"}
