In the eyes of the court, you are an adult when you are age 17. If you were convicted of criminal mischief by a juvenile court, then maybe that conviction can be sealed, but if your case was prosecuted through a regular court (not juvenile court), then the felony conviction will remain on your criminal record forever and you are not eligible to own a firearm.
