Add one to your sample size. Brought my CZ to the range today. Was doing some rapid firing and the Left side of the gun blew. Cracks on upper and lower half the casing was in battery and the back half exploded where it could, so it shredded on the outside face of the chamber. I'm gonna call cz tomorrow.
@ryanm5510 Yes they did! It was under their 5 year warranty. They replaced everything at no cost. Haven't taken it out since I got it back. The lower seems to fit a lot tighter.
@geraldmaloney9230 did they have you send in your firearm and just replace bad parts or did they send you a brand new one? I'm glad to hear they did that for you though
@ryanm5510 Bad parts replacement. The serialized parts are movable into new parts at factory. So on paper it is a repair, but in parts it is essentially a replacement with a serial plate swap.
I had a double feed issue, after clearing it and attempting to fire again, it would not fire and the charging handle is jammed and the round now is stuck in the chamber and trigger does not move, any thoughts anyone as to how to resolve this issue?
Just curious, if you do not have any peening yet on the bolt, will the Nexus striker block have any real effect of stopping the peening from occurring if installed as a prerequisite?
No. It won’t. The problem I discussed in the first video is the issue of the striker block being out of spec and the tolerances allowing the firing pin to move forward irrespective of its position. It does nothing to prevent peening of the bolt. The peening of the bolt is because the 4140 steel used is too soft to stand up to hammer reset. Where these two issues overlap is when the peening on the bolt on the rim of the hole that the striker block sits in begins to prohibit the striker block from moving up and down like it’s supposed to. The striker block fixes the issue of being out of spec but is not a fix for bolt peen.
This is a link that from an OOBD and shows the peen. And how it can prohibit the striker block from working properly www.reddit.com/r/czscorpion/comments/yauntx/postreceiver_explosion_photos/?
@@theuncouthtruth9551 Got it. I was presuming this, but reassuring to hear it from you as well. I appreciate the detailed response. Thank you! Since I am married to my Scorpion (SBR) I will likely pre-order the Nexus enhanced bolt and hope for the best.
In that thread they discuss pre-emptively chamfering the lip of the hole that the firing pin block rides in so that peening of the metal won't cause the block to become stuck, seems like a good preventative option because I do not want to pay $300+ for a harder aftermarket bolt that may cause different issues. If you chamfer the hole and check to make sure your FPB is in-spec and functional, I believe that's as safe as you can get with the OEM parts
@@theuncouthtruth9551I wouldn’t be running a binary trigger, this probably wouldn’t be a problem for me; I’d still probably get the Nexus bolt, though.
@@Airplanetysonthose are nice; I’ve thought about the Scorpion, MPX K, and what not. I have the Zenith Z5, and a Beretta Storm that I’m thinking of SBRing.
Congrats on the baby!
Good video as always brother have a good week
Thanks brother!
Yeah I have this same issue. I send CZ a message on both IG and through the website. Have yet to hear from them.
Write what you hear..I have the same issue
Are you suggesting the need to buy the slide and striker block together? And 10:36 Where can you get the replacement striker
block and slide?

Hey, What was the follow up with CZ if you don't mind me asking? Did they replace it for you?

@@davidunikaev8335 correct. As long as the pocket for the pin block is clear, it’s gtg. It will be something you will have to monitor periodically
So is my scorpion junk , that won’t last?
No. I wouldn’t go that far. Just something to keep an eye on. Could be an issue
@@theuncouthtruth9551is this problem more so if it’s a binary trigger?
@@murkyturkey5238 mechanically speaking yes, the odds of OOBD are much higher
@@theuncouthtruth9551I wouldn’t be running a binary trigger, this probably wouldn’t be a problem for me; I’d still probably get the Nexus bolt, though.
Did you ever hear from CZ after writing to them?
Mp5 is still king , sold my scorpion and went with the classic MP5 POF 5
Well, I don’t think anyone could debate the sexiness of the MP5 platform. Lol.
Ze Germans have a long history of producing excellent weapons for sure.
It’s not a video about debating the scorpion vs the MP5… your comment is moot for the point of this video.
APC9 pro with Glock mags is the new king.
Do you know if the scorpion 3 plus that just came out have fix this issues with a better design?
