if a person was convicted of a non violet felon over 10 years ago how does the person get firearm rights resto?

You need to apply for a pardon either from the governor of your state, or the President, if the offense was federal.

Anyone who has been convicted of a felony is banned by federal law from ever possessing “any firearm or ammunition." Specifically a person "convicted in any court of a crime punishable by imprisonment for a term exceeding one year" cannot possess any firearm in any location. 18 U.S.C. 922(g) is the federal law that prohibits anyone ever convicted of any felony to ever possess any firearm either inside or outside of his home.

However:

18 U.S.C. 921(a)(20) provides:

"Any conviction which has been expunged, or set aside or for which a person has been pardoned or has had civil rights restored shall not be considered a conviction for purposes of this chapter, unless such pardon, expungement, or restoration of civil rights expressly [or implicitly as a matter of state law] provides that the person may not ship, transport, possess, or receive firearms."
