Dan, I can feel your frustration, I'm sure I'm part of the problem.
I have refrained from calling as my weapon is old enough now that 1) it's obviously out of warranty, 2) I've put third party parts in it and that makes any problems with the weapon my problem, 3) you treated me very well when one of the two mags shipped with the weapon was defective so that I have only the most positive experience with Czechpoint.
The problem with the e-clip (prior to the installation of the new FCG) was solved and I hope that current products wouldn't have that problem. I probably should have called to give you a heads up prior to my posting.
I'm embarrassed to say, that I too have gotten the rear bolt cover cocked and had trouble with the bolt carrier, but it's been a long time and I forgot that little pilot error problem.
For the record - Czechpoint, in my opinion, is one of the best organizations I've ever done business with, period.
