I am well aware of the CZ USA Recall. I find it both interesting and humorous that the US branch of CZ felt it necessary to "dumb-down" their version of the Trail rifle by eliminating the Switch-Barrel capability, whereas CZ Europe evidently did not. My CZ Europe Trail has a spot of Red paint on the end of each Barrel Retention Bolt, but that's it in terms of a "warning" against further disassembly. The European manual cautions against disassembly beyond removal of the Bolt from the Receiver and field-stripping of the Bolt itself, but that's it - no epoxy or other means of discouraging Barrel swaps by "qualified armourers", whoever they might be. Perhaps it is just me, but I find it hilarious that CZ USA felt a recall was warranted because incorrect assembly of the rifle was possible, despite clear instructions in the original manual for correct reassembly of the firearm. In other words, they paid for a national recall to epoxy all of the Barrel Retention Bolts on the off-chance that some sausage-fingered, mouth-breather forgets how it is done and reassembles the rifle such that it fires out of battery. Unbelievable, but I reckon that is the litigious USA for ya....
Most of the attraction of the Trail for me is the switch-calibre capability. Take that away, and my interest in a .223/5.56mm-only rifle quickly fades. I want to be able to mix it up with .300 Blk, and maybe even some calibres requiring a different Quick-Change Bolt-Head. Why not? After all, that was half the point of the 600 series in the first place! CZ USA are kill-joy nerds. CZ Europe? Not quite so much!
