Firearm repair question

[original gunner]

When a firearm is sent back to the manufacturer what type (if any) chain of custody documentation is provided? Since the gun is not in the owners hands for a period of time it seems like there should be some documentation that the gun is not actually in the registered owners hands during the time it is being repaired.

There is no registration in Pa.

As such, no "documentation" would ever be required for any firearm not in your possession.

When you send a firearm to a FFL holder the FFL logs the receipt from you and the disposition back to you in his/her bound book.

Again, noting needed on your end.

Good to know. I don't want to be responsible for anything if I have to ship out for repair an the firearm is out of my hands for weeks
