why no love for the XCR-M?

The single screw locking the barrel into the receiver always seemed like a design flaw. There seems to be no secondary measure to keep the barrel from launching down range should the barrel retaining screw loosen.

I've failed to correctly torque the barrel screw one time then did a mag dump for the hell of it. accuracy went to hell but the barrel stayed there. heres why

-the threads are a locking type so the nut just doesnt spin out easily. it would be very very difficult to launch the barrel before you notices the barrel was way loose
-physics makes i kinda hard to send the barrel forward when loose
-the bolt headspaces on the barrel and extention so even with a loose barrel it will only fire if the bolt is locked into the barrel and the bolt has some play to move with the loose barrel

It's kind of a genius design actually. so much leeway to cover for problems.
