{"product_id":"yhm-gas-block-riser","title":"Yankee Hill Machine Co Gas Block Riser – Scope Mount Adapter","description":"\u003cp\u003eThe Yankee Hill Machine Co Gas Block Riser is a precision-machined adapter that elevates optics mounted on low-profile or standard gas blocks. Designed for AR-15 and AR-10 platforms where the gas block serves as a secondary mounting point, this riser provides the necessary height to achieve proper sight alignment with co-witnessed iron sights or red dot optics. It's particularly useful on rifles with non-standard barrel configurations or when converting from a front sight base to a low-profile gas block setup.\u003c\/p\u003e\u003cp\u003eConstructed from aircraft-grade aluminum with a mil-spec hard coat anodized finish, this riser clamps securely to most standard gas blocks with a Picatinny rail section. The low-profile design adds minimal weight while maintaining a solid, repeatable zero. Installation requires proper torque specifications to ensure secure mounting without damaging the gas block. Not intended as a primary optic mount—designed for backup iron sights or forward red dot positioning only.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Gas block scope mount riser\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlatform:\u003c\/strong\u003e AR-15, AR-10, compatible gas blocks with rail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aircraft-grade aluminum, hard coat anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Mil-spec Type III hard anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Clamps to standard gas block rail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Backup sight or forward optic mounting on low-profile gas blocks\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yankee Hill Machine Co","offers":[{"title":"Default Title","offer_id":47940949770495,"sku":"YHM-230","price":45.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1314309.jpg?v=1766568867","url":"https:\/\/doublestackstore.com\/products\/yhm-gas-block-riser","provider":"Double Stack Store","version":"1.0","type":"link"}
