This dual-purpose rail system increases ammunition capacity by six rounds and positions a red dot at co-witness height, eliminating the need for aftermarket optic mounts or gunsmithing modifications to the receiver.\u003c\/p\u003e\u003cp\u003eConstructed from reinforced polymer with a steel mounting plate, the carrier installs using the existing receiver pins on the Benelli M4—no permanent modification required. The integrated RMR mount accepts any optic with the Trijicon RMR footprint. Shell retention is secure during movement but allows quick access with practice. This is a drop-in installation for users comfortable with basic disassembly, though professional installation is recommended if unfamiliar with receiver pin removal.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Side Saddle Shell Carrier with Optic Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e Benelli M4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge:\u003c\/strong\u003e 12 Gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Capacity:\u003c\/strong\u003e 6 rounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptic Mount:\u003c\/strong\u003e Trijicon RMR footprint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Reinforced polymer with steel mounting plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in using existing receiver pins (basic disassembly required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e SureShell carrier with integrated RMR mount, mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mesa Tactical","offers":[{"title":"Default Title","offer_id":47938713682175,"sku":"MESA95260","price":106.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/3568987.jpg?v=1766526267","url":"https:\/\/doublestackstore.com\/products\/mesa-surshl-ply-rmr-ben-m4-6-12ga","provider":"Double Stack Store","version":"1.0","type":"link"}
