Mesa Tactical SureShell 12-Gauge Shotshell Carrier with 4.5" Picatinny Rail for Mossberg 500/590/835 - Aluminum Matte

The Mesa Tactical SureShell 12-gauge shotshell carrier with Picatinny rail is purpose-built for Mossberg 500, 590, and 835 shotguns—the workhorse platforms favored by hunters, home defenders, and tactical shooters. This aluminum carrier mounts directly to your shotgun's receiver rail, putting extra rounds exactly where you need them: accessible, secure, and ready to deploy without fumbling. Whether you're running a door-breaching setup, managing a long hunt, or training hard at the range, keeping ammunition within arm's reach transforms how fast and confidently you can keep your gun in the fight.

Machined from 6061-T6 aluminum and finished in matte, the SureShell uses Mesa Tactical's friction retention system to lock shells in place until you draw them—no springs to fail, no awkward retention straps to fight. The design holds 6 shells of standard 12-gauge ammunition and integrates a 4.5-inch Picatinny rail, so you can add optics, lights, lasers, or other mil-spec accessories without sacrificing carrier capacity. The rigid aluminum construction handles the punishment that comes with field use and doesn't add unnecessary weight to your gun's top end.

Installation is straightforward on any Mossberg 500/590/835 platform. The matte finish resists glare and blends with most modern shotgun setups. If you're building a serious working shotgun—whether for home defense, tactical training, or dedicated hunting—this carrier removes the reload bottleneck and keeps your gun running longer between trips to the ammo can.
