OPSol Texas Mini-Clip 12 Gauge 1-Rd Mini Shell Adapter - Mossberg 500/590

The OPSol Texas Mini-Clip is a compact 1-round mini-shell adapter that installs in the loading port of a 12 Gauge Mossberg 500, 590, 590A1, or Maverick 88 pump-action shotgun, allowing the host firearm to reliably cycle 1.75-inch mini shells in birdshot, buckshot, and slug configurations.

Molded from a durable black polymer and made in the USA, the Mini-Clip installs without tools and snaps securely into the loading port to hold a single round in place at the chamber. Because 1.75" mini shells produce substantially less felt recoil than standard 12 gauge loads, the Mini-Clip is a popular accessory for low-recoil practice, training new or recoil-sensitive shooters, and casual plinking without the punishing blast of full-power buckshot or slug loads.

Beyond its primary role with mini shells, the OPSol Mini-Clip also works with standard 2.75" and 3" shells, and its quick install and removal lets you swap the shotgun between configurations at the range or in the field without ever breaking out a tool kit.
