I am a beretta customer after 5 months of waiting I received my ultra lahit 686 overcoat after 2 days from the purchase I was at the shooting range and after a few shots the rifle broke and no longer fired the second cartridge or I called the Berretta technician and told me that it was not a problem it was enough to bring it back to the armory there was brought it back the year I looked at it and after a few days I took it back I went back to the shooting range after a few shots the rifle does not fire the same defect as before more shots start even alone and a rifle is possible new of 10 days of life paid a raffle a defective shotgun so it must be immediately returned new without any problem. I would like to know how to check the guns now I have to send it back and stay 2 months without the gun .. Thank you for the good impression that I have done at the shooting range with the beretta gun. Yours sincerely.
