This side-saddle carrier keeps additional ammunition immediately accessible without the bulk and weight of aluminum carriers, while the integrated rail provides a mounting platform for optics or accessories. It's a practical upgrade for home defense, tactical, or competition shotguns where fast reloads and accessory mounting matter.\u003c\/p\u003e\u003cp\u003eConstructed from reinforced polymer for durability without excessive weight, the carrier features elastic shell loops that retain rounds securely under recoil while allowing quick extraction. Installation requires removing the trigger group—straightforward for most shooters familiar with Mossberg shotguns, though professional installation is recommended if you're unfamiliar with disassembly. The Picatinny rail segment accepts standard optics mounts and accessories.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Shell Carrier with Picatinny Rail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e Mossberg 500, 590 (12 gauge, 6-shot models)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Reinforced Polymer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e 6 rounds (12 gauge)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRail:\u003c\/strong\u003e Picatinny\/MIL-STD-1913\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Requires trigger group removal; professional installation recommended if unfamiliar with shotgun disassembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Carrier, mounting hardware, elastic shell loops\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mesa Tactical","offers":[{"title":"Default Title","offer_id":47938712011007,"sku":"MESA94880","price":91.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/3568980.jpg?v=1766526164","url":"https:\/\/doublestackstore.com\/products\/mesa-srshl-poly-w-rl-moss-500-6-12ga","provider":"Double Stack Store","version":"1.0","type":"link"}
