Thank you

Put 350 rounds down range with my scorpion. The only complaint is loading the mags-stiff springs. $9 trigger spring and polish really improved the trigger. Larger charging handle and paddle mag release helps. No hiccups. The gun got very warm.
Really easy to clean- pop the bolt out.

Maglula makes a loader for Scorpion mags.

I was horrified with the stock trigger on my CZ carbine.
I immediately ordered the spring kit.
I installed with the included washer figuring it would smooth out the bearing surface on the right side of trigger housing.
I began to have extraction problems after a few hundred rounds. I took the trigger housing out and found a small hunk of plastic at the bottom. I traced the broken off plastic to the area behind the ejector.
I sent the trigger housing back to CZ and they returned a new trigger housing with a new trigger assembly. When I function tested the new trigger I saw that the hammer traveled VERY close to the area mine had broken.I concluded that with the shim/washer installed from HB industries the hammer moved left enough to impact the plastic pedestal the encases the ejector and chipped off a piece, leaving the ejector to flap around.
I also noticed the new trigger CZ sent was WAY better than the original. I probably will not install the HB spring kit.
