Removing the barrel will show you the end of the bolt and not much else.
The suggestion to remove the trigger assembly is the best so far.
Because the trigger assembly allows the firing pin to release, it is connected somehow to the bolt. If the trigger is messed up, then the bolt may have interference in moving.
