I saw these in Germany at IWA 2 years ago, Oberland Arms-its great they are trying the AR. Their gd&t numbers for production were all reverse engineered and not completely correct in the beginning so their magazine wells were odd, a little tight. I spoke with the owner and he told me that he thought that Cook-off was a myth. I thought, well you just have never tried to do it. I think some american companies have helped them get their target dims by now. Those G-mags I heard were not good, but like anything I am sure the first ones were in need of some improvement. Maybe they are working good now.
When you leave the country you must remember that if it comes to the AR, we are very spoiled here with technology and manufacturing. You see the small differences in manufacturers here, imagine what you could see across the world when they are not building from a TDP.
