I have one AR (an RRA) that has a 20" free-floated barrel and a Wylde chamber. With my hand loads, it is the most accurate rifle I have... and I have some dedicated heavy barrel varmint rifles in .243 and .22-250, as well as others. I was really quite surprised after dialing in a new scope and really trying to shoot for groups. Easily under 1 MOA and the thing is... it's easy. There's very little recoil and with a nice trigger it almost does it for you.
The Wylde chambered rifle that I have is markedly better than the other ARs I have, although to be fair, the other rifles have shorter barrels and are not free-floated. Close behind the Wylde chambered AR in my little collection (before I lost it all while boating), is a mere S&W Sport with the original 1:8, 5R barrel. I've found this rifle to shoot better groups that other "well known" brands. Just my observations. I have no complaints about the Wylde chamber.
