Congrats on your new rifle, I am sure you will enjoy it. Just make sure to tighten everything up before heading to the range and then once again after putting some rounds through her. That seems to be the only thing I have heard about them, things tend to work loose during break in. Nothing on mine has, and I got it so early in that nobody knew what to expect as far as what might go wrong. I can honestly say that in the 4K rounds I have put through mine I have maybe had 5 malfunctions. The rifle is great to shoot, and an even greater joy to clean. Welcome again and enjoy.
