{"product_id":"xs-r3d-2-0-glock-21-orange","title":"XS Sights R3D 2.0 Night Sights for GLOCK 21 – Orange Front Dot","description":"\u003cp\u003eThe XS R3D 2.0 night sights deliver a high-contrast aiming solution for GLOCK 21 pistols, combining tritium illumination with a bold orange front dot for rapid target acquisition in any lighting condition. The front sight features a photoluminescent Glow Dot ring surrounding a tritium vial, while the rear sight uses a blacked-out tritium configuration to minimize distraction and drive focus to the front post. This setup works equally well for defensive applications and low-light range work.\u003c\/p\u003e\u003cp\u003eDesigned as a direct replacement for factory GLOCK sights, the R3D 2.0 installs using a standard sight pusher tool (rear) and requires no permanent modifications to the slide. The front sight is staked in place for secure retention under recoil. Constructed from CNC-machined steel with a protective finish, these sights are built to withstand hard use and maintain zero through thousands of rounds.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Night Sights (Tritium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront Sight:\u003c\/strong\u003e Orange Glow Dot with Tritium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Sight:\u003c\/strong\u003e Blacked-Out Tritium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e GLOCK 21\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Sight Pusher (Rear), Staked (Front)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e CNC-Machined Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSight Picture:\u003c\/strong\u003e High-Contrast Orange Front\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"XS Sights","offers":[{"title":"Default Title","offer_id":47940711547135,"sku":"XSGL-R202P-6N","price":128.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2886238.jpg?v=1766566345","url":"https:\/\/doublestackstore.com\/products\/xs-r3d-2-0-glock-21-orange","provider":"Double Stack Store","version":"1.0","type":"link"}
