Well hello guys ,i am a newb,over from the 1919A4 site. I just got my XCR ,from a dealer in Nevada. I love the ergononics of the rifle and the way it handles. I am still going through the break in period ,by the American stuff shoots well.I bought an XCR because i have two friends who bought the 556 ,both of them have had to send the rifles back and havent recived them for over a Mth. I went with the Magpul grips and rail covers ,troy sights ,and thinking about a euro tech.
