This lower mount serves as the foundation for RS Regulate's modular optic mounting system, replacing the factory side rail with a rigid, repeatable platform that maintains zero through repeated removal and reinstallation.\u003c\/p\u003e\u003cp\u003eMachined from 6061-T6 aluminum with a hard-anodized finish, this full-length lower mount provides maximum rigidity and extends the mounting surface for improved stability with heavier optics or night vision setups. Installation requires no gunsmithing—the mount replaces the factory rail using the existing attachment points. Compatible with all RS Regulate upper mounts, allowing shooters to configure red dots, magnified optics, or combination setups to their specific needs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Modular lower scope mount base\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e Yugo-pattern AK rifles with AK-307MS side rail (Zastava M70, M72, M76, M77, M90, and similar variants)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061-T6 aluminum, hard-anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e Full-length profile for maximum rigidity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Lower mount rail, installation hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Base rail for modular optic mounting system; requires RS Regulate upper mount (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RS Regulate","offers":[{"title":"Default Title","offer_id":47939108471039,"sku":"REGAK-307MS","price":150.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2872478.jpg?v=1766539795","url":"https:\/\/doublestackstore.com\/products\/rs-reg-full-length-yugo-modular-lwr","provider":"Double Stack Store","version":"1.0","type":"link"}
