I am a MD resident going to buy a non regulated rifle from a resident in PA. The firearm is a cash and carry firearm in the state of MD. I keep getting mixed answers on what needs to be done to legally purchase. I have been told I need to have him ship it to a md FFL for a transfer. I have also been told that because it is a non regulated cash and carry rifle that there is no transfer required being that there is no registration on non regulated firearms, and that I should be able to buy the firearm with just a proof of purchase such as a bill of sale and nothing more. Can anyone help me out here or have been through this before??
