LWRC are nice, but I'd buy a POF over it.
I heard the same story about an AR.I heard a story where somebody went to a class with an XCR that eventually went tits up.
Care to expound why Texas1911?
I just bought my first AR recently and did a lot of research on various forums. A highly regarded instructor and writer who shoots and sees AR's everyday said there are only 3 (if I remember correctly) he would trust; Colt, LMT & Noveske. Others tend to break often when run hard and are not that reliable.
I went for the Noveske 16.1" Recon because that's what I was able to find locally. I'm going to open up a can of worms here but he also said that the piston rifles are fairly unreliable (he was testing 3 LWRC's and 2 had lot's of problems).
That's just what I learned, In the end you need to decide for yourself and buy what you like...
