Well called Umarex because my Legends model 712 shoots high. Really high like about 3 feet high. The guy had no suggestions. Said I could send it back on my dime but chances would be since the gun functions ok they would figure it was working and send it back. No offer to exchange it. Only advice was use Kentucky Windage.
First and last gun I will ever buy from them. Their lackadaisical reply sealed that deal.
