I can not prove this but it would seem that what little information that has come from CZ about the Brens is bad information. I do not think anyone there is focused on Brens.
My guess is that is going to be a loooooooong time before any thing comes available for compliance kits.
My Brens are high on my list of guns I love but so was my ACR - It would seem CZ is following the same path.
If CZ is going to put information out, I wish it would be uniform and accurate in content.
Again, love my CZ's but I had such high hopes based on their updates that now I feel extremely let down. Going to be a while before I think about buying another CZ product.
