The elevated carrier design keeps shells clear of the action and allows easy single-hand access without interfering with weapon manipulation or sight picture. This is a practical capacity upgrade for tactical, home defense, and law enforcement applications where immediate access to spare rounds matters.\u003c\/p\u003e\u003cp\u003eConstructed from 6061-T6 aluminum with a hard-anodized black finish for corrosion resistance. Installation requires partial disassembly of the receiver—the carrier mounts using existing trigger group pins and screws included in the kit. Basic mechanical aptitude and punches are needed; no permanent modifications to the shotgun. Shells load and eject positively with the spring-loaded retention tabs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Shell carrier \/ side saddle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e Mossberg 590 12-gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e 6 rounds (12-gauge 2¾\" or 3\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061-T6 aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Hard-anodized black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in using existing receiver pins (requires disassembly)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Mounting hardware and retention springs\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GG\u0026G, Inc.","offers":[{"title":"Default Title","offer_id":47943568982271,"sku":"GGG1515","price":91.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1267740.jpg?v=1766586213","url":"https:\/\/doublestackstore.com\/products\/gg-g-moss-590-6-sht-side-saddle-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
