Mesa Tactical SureShell Polymer Carrier for Mossberg 500/590 12 Gauge

The Mesa Tactical SureShell Polymer Carrier adds side-saddle shell capacity to Mossberg 500 and 590 shotguns without adding excessive weight or interfering with optics mounting. This polymer carrier holds four 12-gauge shells securely on the receiver, keeping additional rounds within immediate reach for tactical applications, competition, or hunting situations where fast follow-up shots matter.

Constructed from high-strength polymer with a matte black finish, the SureShell carrier installs on the left side of the receiver using the existing trigger group pins—no drilling or permanent modification required. The injection-molded design offers excellent shell retention while allowing quick extraction under stress. Compatible with most factory stocks and aftermarket accessories.
