not exactly, but it was one of the early ones, I had it about 8 years or so. I remember they had a 453 sitting next to it, but the barrel swap option got my attention.
I asked because it seemed like a LOT of the early 455s had accuracy and other issues than seem to be linked to the switch barrel.system.
I think it took CZ a while to get the tolerances down on that setup. The basic barrel attatchment design must be OK since they incorporated it into the new 457.rifles.
