barrel and bolt combination...

so I have read all over that mg34s are finicky on barrel bolt combinations, my question is when you do have a pair that is mismatched what does it do? light strike? not unlock correctly?

Depends on whether it's too tight or too loose. Too tight, and the firing pin may release before a complete lock up. Too loose doesn't seem to be as much of a problem, but just right is best.
Just right is determined with headspace gauges.
Frequently, people just try a few combinations until one works properly, then they mark the pair and shoot them together. Not exactly the wisest choice I think, but I've seen it done dozens of times.

My experience is that bolt barrel combinations do need to be tested for compatability. I did not consider it important, but when I was having problems with my mg34 semi I tried all different changes, but it only started to work when I changed the barrel! The problem I was having was failure to eject, seemed as though the locking was to tight.
