Manufactured by CMMG from \u003cstrong\u003estainless steel\u003c\/strong\u003e, this action spring is engineered to the same dimensions and tolerances as the original equipment component to deliver consistent, long-lasting performance in the buffer tube assembly.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eAs a key part of the buffer and spring assembly, the action spring works in concert with the buffer and buffer weight to control the rearward and forward travel of the bolt carrier group. Its rate and tension are calibrated specifically for carbine-length gas systems, providing the balance needed to ensure reliable cycling, consistent lockup, and proper ejection across a wide range of ammunition. The spring is compatible with most \u003cstrong\u003eMil-Spec AR-15\u003c\/strong\u003e carbines and serves as a straightforward drop-in replacement for worn or out-of-spec springs during a build, refresh, or routine field service.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eWhether you are assembling a new carbine from the ground up, refreshing a well-used rifle, or simply keeping spare components on hand, this CMMG action spring is a cost-effective way to keep your AR-15 running smoothly. The corrosion-resistant \u003cstrong\u003estainless steel\u003c\/strong\u003e construction holds up to long-term storage and repeated cycling, making it a smart bench staple for any AR-15 builder or armorer.\u003c\/span\u003e\u003c\/p\u003e","brand":"CMMG","offers":[{"title":"Default Title","offer_id":55291988279618,"sku":"55CA9A2","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/alt_91f139c6-f7a6-4223-a319-bf259e4d1c92.jpg?v=1785102111","url":"https:\/\/centerfiresystems.com\/products\/cmmg-ar-15-carbine-action-spring-mil-spec-stainless-steel","provider":"Centerfire Systems","version":"1.0","type":"link"}
