I've had my share and several other of their products. I currently have a CDL SF LE in .260 and just picked up a 5R, also in .260. The CDL was part of the x-mark recall, but is an awesome lightweight hunting rifle. I slapped a Timney in it and problem solved. I haven't even shot the 5R yet. Waiting on optics.
I'm not doubting your experience and you sound like a picky bastard, as am I. I think the world, these days, is run by HR and bean-counters. As far as current production QC, I'll reserve judgement and give them the benefit of the doubt until I see how the 5R shoots. If it doesn't, back it goes.
I buy them because I like to tinker and prove I can get them to shoot as well as rifles that cost a lot more. You can't really compare them to high dollar GA Precision like rifles, where they have much smaller production runs and a closer eye on QC. I have seen people griping about almost all manufacturers at some point or another. It's built into the system. The more popular a gun becomes = more sales = larger production runs = more tools that wear out = more chances of out of spec guns leaving the factory. They are like cars. Each one of them have their design flaws and it's just a matter of time before you see them. That's what fuels the aftermarket. I always buy my cars without the crap I know I will replace, like the audio system.
