I know there legal to own but I don't know if they will sell them to Ohio residents. I posted in their EE ad asking them this and also emailed them but I haven't gotten a response yet. Thanks
Copes Distributing Inc. They did in 2010.

I would think so. No crime in owning them, unless you stick em in a non NFA weapon.
I believe they are located in OH. I'd hope they know the OH laws :D
They are in Greenville. Call and ask. Im sure they do.
