SKU: opsol®-mini-clip-2.0-flex Category:

The OPSol Mini-Clip 2.0 FLEX lets you shoot those little 1.75” shells. It is an adapter placeable in the receiver of most 12ga Mossberg® pump action shotguns. It fills in space in the receiver and effectively creates a snug backstop and pathway for incoming shorter 1.75” shells. This greatly reduces dead space in the receiver, so the smaller shell doesn’t rattle around during cycling, risking a flip. The results of stressful conditions and odd gun positions/angles are greatly decreased because the OPSol Mini-Clip 2.0 FLEX allows for almost no movement of the short shell as you rack the gun. Sometimes it’s better to do one thing, and do it right. Need to run your full size shells again? Poke your thumb through the open ejection port and pop it out. Takes about 3 seconds.

Make the OPSol Mini-Clip 2.0 FLEX part of your affordable solution for home defense. Paired with the 12ga Mossberg® 500, 590, Shockwave and Maverick®88 platforms, and potent 1.75” short shells, you’ll have at least 9 opportunities to better handle SHTF, home invasion, and the general protection of yourself and family.

Those 1.75” MiniShells® and short shells (we call them Hater Tots®) reduce recoil and tame that 12ga so that not just you, but most of your family members have a home defense platform that they can practice with and effectively use if the situation calls for it. You may not be home when the SHTF. Get your OPSol Mini-Clip 2.0 FLEX today.
