Shotar's right about the city ordinance thing. Ohio law relies on the cities to regulate the assault weapons type issues, but they do have their loose parameters from the FEDS. Good luck trying to get your city lawmakers to explain what's legal and what's not legal. Before I bought my AR, I wanted to know what the city ordinances were in Columbus affecting AR's and mag capacity and the like. I called CPD, Franklin County Sheriffs' Dept., the city Prosecutors' office, and the District Attorneys' office. Everybody told me to call someone else, b/c they weren't clear on the laws!!! (WTF am I paying my taxes for then?) The lady in the District Attorneys' office, who stated that she was the one who dealt w/ these laws told me she didn't know, and to ask at my local gunstore!!! She also told me I could hire an attorney to look into the matter for me! (WTF is she?).
Long story short, nobody in Columbus can explain the city ordinances. Gun store said I can have 30rd mags, so I guess I must be ok...hehehe.
