This kit provides the components needed to convert or extend your shotgun's magazine system, giving you significantly increased capacity for competition, tactical applications, or extended field use. The MXT system is designed for reliability under high round counts and demanding conditions.\u003c\/p\u003e\u003cp\u003eMachined from aluminum with a black anodized finish, this kit maintains a lightweight profile while providing durability. This is a kit configuration that requires a separate magazine tube nut for installation (not included). Installation requires disassembly of the magazine tube and familiarity with shotgun mechanics—professional installation is recommended if you're not experienced with magazine tube work. Nordic Components engineering focuses on consistent feeding and minimal added weight per round of capacity gained.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Magazine Extension Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e 12 Gauge shotguns with compatible magazine tube systems (verify fitment for your specific model)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e +8 Rounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Professional Recommended\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e Magazine tube nut required (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Nordic Components","offers":[{"title":"Default Title","offer_id":47938525921535,"sku":"NCMXT-TBS-12-8K","price":73.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1282589.jpg?v=1766518445","url":"https:\/\/doublestackstore.com\/products\/nordic-8-mxt-kit-12ga-bk-needs-nut","provider":"Double Stack Store","version":"1.0","type":"link"}
