{"product_id":"luth-ar-308-rifle-buffer-spring","title":"Luth-AR .308 Rifle Buffer Spring – AR-10\/LR-308 Pattern Rifles","description":"\u003cp\u003eThe Luth-AR .308 Rifle Buffer Spring is engineered specifically for AR-10 and LR-308 pattern rifles, providing reliable cycling for larger-caliber semi-automatic platforms. This spring is designed to handle the increased bolt carrier mass and recoil impulse of .308 Winchester\/7.62x51mm NATO rifles, replacing worn or underperforming factory springs that can cause cycling issues or premature wear on internal components.\u003c\/p\u003e\u003cp\u003eConstructed from high-tensile spring steel with a durable finish, this buffer spring is a direct drop-in replacement requiring no gunsmithing or modifications. Installation takes minutes with basic disassembly of the buffer tube assembly. Upgrading to a fresh buffer spring restores proper timing and can resolve short-stroking, bolt bounce, or excessive felt recoil in .308 AR builds.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Rifle Buffer Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-10, LR-308, and .308 AR pattern rifles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-tensile spring steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Corrosion-resistant coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in, no gunsmithing required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e (1) .308 rifle buffer spring\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Luth-AR","offers":[{"title":"Default Title","offer_id":47938417459455,"sku":"LUTH308-BS-10B","price":7.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1289967.jpg?v=1766513773","url":"https:\/\/doublestackstore.com\/products\/luth-ar-308-rifle-buffer-spring","provider":"Double Stack Store","version":"1.0","type":"link"}
