Tried various search parameters to see if this has been posted. Closest thing I found pertained to "gifting." Question: if I'm looking to trade a firearm, is it a legal issue if someone contacts me and says: (1) he wants what I have to trade. (2) his friend has the firearm I'm looking for. (3) he will buy the gun from his friend. (4) he'll trade the firearm he buys from his friend for what I have. So he's looking to buy a gun in order to trade for what I have. Legal? Just want to make sure everything is done properly. Thoughts, ideas, facts?
