Not necessarily related but I'll reiterate that dealing with Beretta is your best bet. Whether the gun was damaged or not, I don't see the seller as being in any way on the hook for this.

FWIW just a couple of months ago I discovered (from another member here with whom I was trying to do a trade) that my CZ rifle had a cracked stock. I was the original purchaser but the warranty CLEARLY stated that wood parts were only covered for 1 year. I bought the gun just under 5 years ago.

Despite the fact that the wood stock was almost 4 years OOW on the stock, CZ replaced the stock at no cost to me (to include covering ALL shipping costs, to and from CZ.)

IMO always worth it to try to deal with the manufactuer for two reasons: 1. The cost to them is negligible in the great scheme of things and 2. Cultivating "good will" is a part of most manufacturers who want to protect their reputation. So even if you technically aren't covered by warranty, often times the manufacturer will "make it right" for you.
