Sorry to hear of your friends passing, but great gesture giving it to his son. Hope it works fine after the update.
I hope it works fine too. Thank you for the condolences about my friend.
Don't give me too much credit. My friend bought the rifle from me years ago. It isn't mine. In the "fog of divorce" I ended up with it. I don't know who it rightfully should go to, but I picked the person who bought it to start with. He unexpectedly passed. His son is the logical choice. All I would do is sell it or trade it, and that wouldn't be right.
