everything gun related is legal here.... with very few exceptions. If I ever left Indiana I would have to got a state with very relaxed gun laws...lol So bring your silencers your assault rifle clones. or your other NFA items. Find a range and enjoy our great state before it goes communist like every place else.
I'd advise going the trust route. Its easy, print off a generic living will trust that you say you'll place your NFA items into or whatever u want, get a notary to sign it. No fingerprints or CLEO.
