I own an early RRA that was purchased as two separate halves. They fit tight and function flawlessly. Each half is covered by a warranty, but the rifle, assembled complete would not be covered. Basically, in the event of a problem, I'd ned to isolate it and deal with the corresponding half. I'd assume the same to be true for this Stag-Bushy rifle, but the fact that the pins were reveresed screams "build" to me, and I wouldn't expect it to have any warranty. If they were purchased as complete halves, it would be wise to inquire if he has any proof of purchase on them. It would prove to you who assembled them, and might come in handy if the manufacturer requests to see them for warranty work.
