{"product_id":"hf-ak4-ak74-braided-main-spring","title":"Hiperfire AK47\/AK74 Braided Main Spring – AK Rifles","description":"\u003cp\u003eThe Hiperfire AK47\/AK74 Braided Main Spring replaces the factory hammer spring in stamped and milled receiver AK variants. This upgrade addresses the common issue of inconsistent hammer strikes caused by worn or weakened factory springs, restoring reliable ignition with both military surplus and modern ammunition. Particularly beneficial for rifles experiencing light primer strikes or those used with harder primer ammunition.\u003c\/p\u003e\u003cp\u003eManufactured from braided music wire for consistent tension and extended service life compared to conventional coil springs. The braided construction resists taking a set over time and maintains constant force throughout its compression cycle. Drop-in installation requires no permanent modifications—simply disassemble the fire control group per standard field-stripping procedures and replace the existing hammer spring. Compatible with standard AK trigger groups.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Hammer Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AK47, AK74, stamped and milled receivers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Braided music wire\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) Braided main spring\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hiperfire","offers":[{"title":"Default Title","offer_id":47938178089215,"sku":"HIPXAKMS","price":8.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2947282.jpg?v=1766506605","url":"https:\/\/doublestackstore.com\/products\/hf-ak4-ak74-braided-main-spring","provider":"Double Stack Store","version":"1.0","type":"link"}
