The two groups taking action are Ohioans for Concealed Carry and Buckeye Firearms Foundation.
10TV has learned the groups are asking for a preliminary injunction against the new laws, as well as a temporary restraining order.
The groups are arguing two main points:
It is unlawful to ban bump stocks because of Ohio's Code 9.68 that gives people the right to, in part, keep any firearm, part of a firearm, its components and ammunition. The groups say bump stocks are considered components.
Part of the law takes certain state and federal felonies, like possessing firearms if you've been convicted of a crime, and turns them into misdemeanors.
