CaptianGyro,Welcome to the forum.
You say you experienced a "bolt failure" which led to a damaged receiver, but that everything except the receiver is "better than good". That is fairly confusing...what about the aforementioned bolt?
Sorry for the confusion. I thought it would be obvious with a stated bolt failure that damaged the bolt locking shoulders didn't have to be re-mentioned. My Bad!
Yes, you are probably correct about parting the parts out. There is a gun show coming up this month down here. That might be a good venue to look into.
I do thank you for taking the time to respond. Oh, I have attached a couple of photo's of the bolt and receiver lug.
