Hello and I am happy everything turned out so well for both you and your rifle. Everyone and every company seems to have an off day, but from what I have personally had help with and the responce time I have gotten from CZ-USA I think they seem to go a long way to minimize those off days be it customer service or QC issues. Thanks for keeping us in the loop so we know how it worked out.
BTW I am not a long gunner by any means. I bought 2 different ones a year ago so I could finely learn how to shoot one (it was on my bucket list) properly. Anything in the small arms up to and including riotguns and sub-machine guns and strangely the 50 Cal. Machine gun I can handle and well. But long guns have allways defeated me, with the exception of the .30 cal carbine. (maybe because it was shorter and lighter?) which brings me to this part.
Welcome to out Forum from FL. I don't always go through every Board, because some of them I know not a thing about and others do, but I do get around to it and so that's why this Welcome is a bit late. We are happy you decided to join us, as we try to give as much information and help to folks as we can, or point then towards where they can find the information if possible. We also like to meet new folks, learn and or teach new things, and have fun doing so. If you happen upon a question that someone asks either here or on other Boards and you can answer it please feel to do so. So have fun, and let us know how the rifle is working now.
