I'm probably the only one here unhappy with mine. It was the 223 American, thought it was a real cute gun, put a fixed 4x leupold on top, real nice handy package. The damn thing would not shoot(reloads or factory, yes I tried different grain weights also), and the bolt was rough and would rack while fully open and bind so I couldn't close it quickly at all. Drove me nuz, had to trade it of quick. That said, I'm willing to give the 527 another try if I find the right deal, as there are a lot of things I like about the package.
