Charged With Reckless Conduct can i get it off my record

I was in the car with 2 other of my friends. the car was my friends i was just a passenger. We had a BB gun that shoots plastic balls. This was in a college parking lot. I pointed the pistol at my friend who was sitting in the backseat and she knew it was a fake gun. someone passing by saw this and called the police. my other friend pointed the gun out the window so he is also getting charged. it is his gun and its his car. They are saying i could have caused harm to students but they argument is that it could have causes a traffic accedient. my question is should i try to fight it or just plead guilty. and is there a way to get it off your record? i dont want something this stupid to mess up my future. they also didnt tell me my miranda right if that accounts for anything
