Yup, as a "private party" you can sell ANY gun to anyone 18 and over. Handgun or rifle.

And as theGinsue said, any paperwork will stop a sale with many of us.

I PM's someone selling something, and asked if he required any paperwork, since he DID NOT list it in his ad. He said he did. Stopped the negotiations right then and there for me. He should of had his requirements in his ad.

Can I pass a background check. Yup. Have before.
Will I, or involve any paperwork for a "private sale"? Nope, no more.
My loss, but I can be stubborn that way.
