Ok so I am getting fail to eject from my CZ Scorpion.

The question I have is this:

Does your ejector move when you place your thumb on it? Mine moved up/down a pivots on a pin it feels like.

How does yours react?
 
Up and down movement is slight, maybe a couple of mm.

When looking at the firearm from the back ejector movement when pressed appears to be approx 1/8" - 1/4" to the 7 o'clock position, pivoting, with a spring returning it back to the original position.

Up and down movement is fine.

Was it limited to one magazine, or did it happen with multiple known good mags?
Unknown at this time.

I wanted to rule out the ejector first before doing a magazine test fire.

I do think it's a magazine issue, but not 100% sure
 
Any idea of the round count?

I've got a friend with a full auto scorpion. Around the 20k round mark, it broke the extractor.

On MY scorpion, it is magazine picky. Works great with PSA AKV mags and the smoked CZ mags. I get nothing but fail to eject's with Magpul mags and CZ windowed mags.

Same experience with magpul mags here.
 
I have avoided the Magpul mags for said reasons. I've got a Scorpion circa 2015, and it runs great with OEM, Manticore, and PSA mags. I've broken the disconnector on mine (actually it was @Bocephus daughter who did it whilst shooting) but apparently it is common on the first gens, and they sell a beefier one.
 
To all,

Thanks for in information. I had no idea the MagPul mags had any issues. I have been so busy with work I have not had a chance to go confirm its only a mag issue.

Are you talking about CJ in Sanford?
