Dude what is the point of a heavy 5.56 cal weapon unless your shooting prairie dogs or coyote's at 500 yards? In that caliber I want as light as possible. Now some can shoot better than I and don't mind dragging around a 10 pound full up gas gun in 22 caliber. For that weight I want to hit harder.
I have one. Mine has been a solid rifle. Respectable accuracy and none of the carrier tilt I experienced with a first gen LWRC i owned. That said for the same money I'd still get a Noveske, DD, or KAC as others suggested.
