Opsol Texas MINICLIP: The OPSol Mini-Clip was designed to give \"well seasoned\" and \"recoil sensitive\" shooters the capability of shooting mini-shells in the trusty Mossberg 12GA platform without the usual recoil response. Mini-shells are a great option to increase capacity and shoot with reduced recoil, but their shorter length can cause feeding issues in an action designed for standard 2 3/4\" or 3\" shells. The Miniclip is an easy-install accessory that prevents more than a single mini-clip from feeding at a time, to ensure reliable cycling of your shotgun with these rounds.
