I've had a Stag for 4 years now and I use it a lot. I have nothing bad to say about it. It has never failed me in feeding, ejecting, or anything else, never, and it's dead balls accurate. I would put it up against any other AR.
Before Stag started making rifles, they used to make parts for NASA space missions. I think they know all about precision work.
