There was sort of a resolution. They did provide me a gas valve with smaller holes. It helped significantly, but I did have another stovepipe on a spent case this weekend. Aside from the over gassing, I think that another issue is the ejector. Most of the spent cases hit at the rear of the ejection port. They then bounce forward to about 12:30, often hitting the fingers of my left hand which are wrapped around the handguard. In the case of the picture below, the spent case hit the rear of the ejection port, bounced forward to hit the front of the ejection port and then got caught by the bolt carrier going forward. The design of the ejector spring seems odd to me. Why so long? I just don't think it provides enough force to get the case out quick enough.





In spite of the fact that the ergonomics are great, I would not recommend buying one. CZ has failed to support the platform and it doesn't look good going forward.
