Who knows. There were a great number of very good rifles in the trials.
Just because you aren't having problems with a completely different firearm, doesn't mean that your problem with the XCR wasn't user related. You say you had a "problem" what kind of problem? A stoppage? Could be a lot of things, gas setting too low for example, or it could be you had a PMag with a pin that was preventing the mag from seating properly, or you or your buddy may not have cleaned it properly. A better question is: Is he STILL having issues?
Another logical leap, I'm afraid. A firearm that has been never fired and has an issue during break in may never have a problem again once properly broken in. Robinson torture tests their rifles just as much as anyone else.
Third day up with my XCR, one of our local guys was up with a brand new Hi Standard DI AR. Couldnt get through 3 rounds of wolf without a stoppage and eventually he had to borrow my mallet, ballastoil, and some Federal to try to get through the break in.
My 20th round in my XCR was stuck in the chamber unfired and I couldnt get the bolt out... A lube issue during Break in.
Every round since has been perfect... It was also a good learning experience with a new rifle...
The question is not whether you gun will F up but how you deal with it when it does...
