Frequently Asked Questions


Which Mossberg firearms does the OPSol Mini-Clip work with?

12ga Mossberg 500, 590, 590A1, Maverick 88 and the 12ga Shockwave Firearm.


Does the OPSol Mini-Clip work in any brand other than Mossberg?

No. Because of timing and extraction considerations, the Mossbergs are the only platforms we've been successful with.


Does the OPSol Mini-Clip work in Remingtons or Winchesters?

Because of timing and extraction considerations, we were unable to get an adapter to run in the Remingtons or Winchesters.


Does the OPSol Mini-Clip work in Semi-Auto Shotguns?

The short shells have a problem double feeding from the magazine tube with all the semi-autos we’ve tried.  In addition, timing and extraction of the semi-auto systems are just unfriendly to the shorter shells.


Does the OPSol Mini-Clip work in Mossberg 20ga shotguns?

No. Waiting on Aguila to get us the specs for their upcoming 20ga offering.  We've made prototypes and they work well.


Does the OPSol Mini-Clip work in Mossberg 535 shotguns?

Short answer is no. Have had guys cut Mini-Clips shorter (feeding well is actually shorter than the 500s etc.) to run in the 535s.  Never received any positive feedback as to it ever functioning in any regard.
