The bolt seemed stiff to me but I attributed that to lack of use. I may have been wrong.
If the bolt is "stiff" and doesn't move in and out easily in the carrier, the gun will only function as a single shot.
Had an experience with a friends AR, the bolt was so dirty it did not move in and out easily, once we sprayed it with WD and lubed it, it started functioning correctly.
Seen it on another AR as well, make sure it's clean enough to move easily back and forth within the carrier.
