This is my first post on this forum. After searching for years, I finally was able to purchase the Beretta 92 .22LR Practice Kit from the Beretta web site. They were sold out in a couple of hours. Inside the case is a round blue cup with the Beretta logo on the bottom. I don't have a clue what it is for. I'm guessing that it is to keep the plastic case from being crushed during shipping. Does anyone know what it is for?
