Looking for an easy, inexpensive way to enhance the capacity and lower the recoil of your 12-gauge shotgun? It's possible with the addition of the OPSol Mini-Clip 2.0!
This small aftermarket adapter fits easily into the opening located under the receiver of any Mossberg 500, 590 590A1, Shockwave or Maverick 88 12-gauge shotguns.
Once installed, the clip allows for reliable cycling of 1.75-inch shotshells straight from the magazine. Want to shoot longer shells? The clip comes out just as easily as it went in, taking mere seconds.
