The Mesa Tactical SureShell Carrier is a purpose-built side saddle solution designed to keep eight additional 12-gauge rounds within arm's reach on your Remington shotgun. Whether you're running competitive stages, training at the range, or preparing for home defense, this aluminum carrier delivers the added capacity where it matters most.
Mesa Tactical machines these carriers from 6061-T6 aircraft aluminum, a material chosen for its strength-to-weight ratio and corrosion resistance. After precision milling, each unit is bead blasted and finished with mil-spec hard coat anodizing, producing a subdued matte black surface that won't reflect light and resists wear from daily use. The engineering here is straightforward but uncompromising: a solid mechanical platform that refuses to flex or move once mounted.
Instead of relying on tight-fitting holes or complex springs, the SureShell uses a friction-based retention system built around rubber elastomer inserts that grip shells securely without excessive force. This means shells stay put during movement and recoil, but come out easily when you need them. The system accommodates both top and bottom loading, giving you flexibility in how you manage your carrier. Each SureShell ships with standard black rubber installed for typical shotshell loads, plus harder white rubber alternatives included for specialty or softer-bodied ammunition.
The carrier attaches to your shotgun receiver using application-specific brackets secured with steel fasteners. Installation requires no gunsmithing, and all required hardware ships with the unit. Mesa Tactical includes high-temperature adhesive-backed rubber gaskets on the mounting plate to protect your shotgun's finish from the metal backing plate. The mounting design includes a window over the serial number location, allowing quick inventory checks without removal. Made in the USA and backed by Mesa Tactical's lifetime warranty.
Yes, the 90420 model is specifically designed for Remington 870, 1100, and 11-87 pattern shotguns. It mounts directly to the receiver using the trigger group pin holes without requiring gunsmithing. Make sure to verify compatibility if you have a heavily modified 870 with significant aftermarket work.
The black rubber inserts provide standard retention and ship installed on every carrier. The white inserts have a harder durometer rating and are better suited for specialty ammunition or situations where you want slightly less grip. Mesa Tactical includes both sets so you can swap them based on your ammunition preferences.
Yes, the carrier mounts directly to the receiver without gunsmithing. Installation typically takes just a few minutes with basic hand tools. All required hardware is included, and Mesa Tactical recommends using a small amount of blue Loctite on the fasteners to prevent loosening from recoil.
The 8-round configuration is larger than the 4 or 6-round versions and may contact certain forends or grips depending on your 870's setup. Some users with standard forends report it fits without issues, while others with Magpul MOE or similar tactical forends may need to check clearance. Testing before purchase is recommended if you have significant aftermarket components installed.
