This spring works with the buffer assembly to control bolt carrier group travel, manage recoil impulse, and ensure consistent feeding and ejection. Replacing a worn or weakened buffer spring can eliminate cycling issues, reduce bolt bounce, and restore proper function to your rifle.\u003c\/p\u003e\u003cp\u003eManufactured from heat-treated spring steel with a corrosion-resistant finish, this buffer spring is a direct drop-in replacement requiring no gunsmithing or special tools. Standard AR-15 buffer springs typically have a service life of 5,000–10,000 rounds depending on use; replacing the spring during routine maintenance helps prevent malfunctions before they occur.\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 and AR-15 pattern rifles (mil-spec buffer tubes)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-treated 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) Buffer spring\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ATI Outdoors","offers":[{"title":"Default Title","offer_id":47943505903871,"sku":"ADVA5101030","price":5.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1240097.jpg?v=1766580720","url":"https:\/\/doublestackstore.com\/products\/adv-tech-ar15-buffer-spring","provider":"Double Stack Store","version":"1.0","type":"link"}
