Unlike traditional buffer springs that can ping and vibrate, this kit uses a series of nested, captured springs that dampen sound while maintaining consistent cycling pressure. It's a popular upgrade for shooters who want a quieter, smoother-running carbine without changing how the rifle operates.\u003c\/p\u003e\u003cp\u003eThe kit is compatible with H and H2 buffers and installs as a drop-in replacement—no gunsmithing or permanent modifications required. The captive spring design also reduces wear on the buffer tube threads. Made from heat-treated steel with a durable coating, the STLTH system is built to withstand thousands of cycles. Installation takes minutes with basic tools.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Recoil Spring Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 carbine-length buffer tubes (H, H2 buffers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-treated steel springs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Protective coating\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 Captive recoil spring assembly, installation hardware\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Armaspec","offers":[{"title":"Default Title","offer_id":47934614175999,"sku":"ARMASPECARM253-AR15KIT","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2854981.jpg?v=1766473313","url":"https:\/\/doublestackstore.com\/products\/armaspec-stlth-rcil-sprg-kit-c-h-h2","provider":"Double Stack Store","version":"1.0","type":"link"}
