FYI CZ Scorpion Evo 3 S1 issue and remedey

[syntaxerrorsix]

I unloaded a few 30 rounders today at the 25 yard line. Offhand I typically group about 2.5-3". Today on the second magazine I went from hero to zero and spent about 450 more rounds to rectify the situation. 

 

The second magazine landed exactly 6 hits all over the map. I went supported and wasted another two mags. 

 

I killed the red dot and went irons and did marginally better. 

 

After getting home and stripping down the gun I found that the thread protector under the flash suppressor had unscrewed and was stuck in the flash suppressor. I was shooting the thread protector and causing errant hits. 

 

The thread protector was fairly well hammered in to the flash suppressor but once I got it out and threaded everything back together I started making money again. Decided to just ditch the thread protector after I got home. No need with the flash suppressor installed. 

 

I was certain my red dot had lost it's marbles but once again, operator error reigns supreme. 

 

Hope that helps someone.

It's good you corrected the problem and something to keep in mind for Scorpion owners.

They and suppressors do have a bad habit of unwinding themselves.

New problem has crept up on me.  The right side receiver plate sling attachment has broke off.  I had the Parker Mountain Machine QD sling point attached and was shooting with the sling offhand when it broke.  I can only assume I had bumped it or damaged it along the way because I wasn't putting too much force on it.

 

Bottom line is the right side receiver plate IS the firearm because that;s where the SN plate is located so there is no way to replace it without buying a new firearm.

 

****.

 

So I pulled out the dremel and finished it off smooth and ran the sling through the brace loop.  CZ stated that as long as there wasn't a hole all the way through the plate I was good to go.  I imagine even if there was a hole the only concern would be dust and dirt.  Lesson here?  If you are shooting left handed don't use the rear receiver plate swivel or you might end up having a bad day.  The left hand receiver plate is replaceable and costs about $30....
