I had one of their stripped lowers. They seem made very well. In essence, they are a very good brand to go with in building your AR-308. I wouldn't hesitate using it. Compared to my POF lower, the quality and feel are the same. Also, my brother's AR-15 has a tactical machining lower and it seems really well built too. I believe all their lowers are good to go. They are also very well known company on other forums as well such as Calguns.net, that is where I prowl most of the time.
