Here's a cliff's notes version. There is a big controversy over barrel suppliers. At first they were bartlein/tooley, now they are green mountain/other. Some people are having issues with accuracy. Others are not.
I've shot one, it's a friend of mine's gun. It's the 16" 308 and doesn't have the bartlein barrel. I shot one group with 168 fgmm and it was slightly under one MOA. He has tried a bunch of ammo in it, including some handholds that were for another gun. It shoots anywhere from .75" to 1.5" depending on the ammo. My educated guess is this; the guns don't shoot bugholes, but I suspect some of the issues people are having are the shooter not the gun. It is not an easy gun to shoot, especially if you are used to a 15# or more 6mm or 6.5mm. It will expose your mistakes big time.
With that being said...I want one. If you handle one you will understand why. The gun naked, no scope, bipod, suppressor, etc. weighs a little over six pounds. It is magazine fed, adjustable stock, folding stock, full length handguard, awesome two stage trigger, user changeable barrels without a bench or vice, great ergonomics, and awesome bolt throw. People complain about the bolt throw. It's definitely different, but it is not bad at all. It's just something you have to get used to. You really can't build anything like it. For it's intended purpose, which to me is a short, light, handy, hunting/field gun, it can't be beat. If you get one and it doesn't shoot well enough for your intended purpose, just have a barrel spun up for it that will.
