+1 on the XCR. I've had one for over a year and it is a very well designed rifle. Have had no problems with mine whatsoever. I, too was considering 556, but I couldn't stomach the stock either. I think I made the right choice. It is just as or more accurate than an M-4. The best thing about it is the way RA is standing behind their product. Pity more people don't consider the XCR when looking for a piston rifle. Only drawback is the price, which is not all that bad considering you're getting a free floated quad rail in the deal.
