5 weeks ago I sent my scorpion back to cz for a damage bolt catch lever causing the bolt not to lock back or drop when the mag was released. Got it back today new lever installed gtg. Got it home to test my mags make sure all was well. Factory 20 and  30 rounds work perfectly, the prepper 32 round mags will not push the hold open up enough to lock the bolt.

After playing around and watching what happens when hand cycling sometimes the catch would go up just a bit and the bolt would just hit top of the catch and stop but just barely. I believe over a short  time this case the part to fail as it was not making contact with a large portion of the bolt catch only the tip.

On top of all that one of the 32 round mags where the metal feed lip clamps to the plastic is broke.

I'll be emailing prepper tonight about the magazines


Here is what happened to the bolt catch
