CZ USA made this rifle until a seven or eight years back (I think) it was called the CZ511. I have one of the Brno 581's and when my sear was worn to the point of going full-auto when I squeezed the trigger I called CZ. They had no major parts for this rifle but the guy said they might have some small bits somewhere. Five months later the guy sent me an email, followed by a package in the mail with all the remaining trigger parts they had in the warehouse, no charge. When I emailed to thank him I asked if they even has any broken magazines lying around and was told no. I love this rifle. I'd like to find another mag as well. I may need to just make one eventually.~Muir
