$1675 shipped, you cover insurance if you want it. Insurance will probably be about $20.
And before anyone else's time is wasted, let me be clear on a few points:
1. If you are NOT an Idaho Resident, then I will only ship the rifle to an FFL in your state. (Lower 48 only). It is against the law for me to have the rifle shipped to you directly, and it is against the law for me to transport the rifle to you... even if you just live across the border in MT, UT, or WY. Also, even if you want to meet in Idaho, if i know you are not an Idaho Resident, then we need to use a local ffl. Still cost us probably $20 to have them transfer it to you. (However, the law does not require me to "card" you, so if you are physically in the state of Idaho to meet me, and i do not otherwise know that you are NOT an Idaho Resident... then technically i can sell you the rifle face to face if I choose to not ask for ID. But really, if I see you drive up with WY plates, I'm going to "know".) I get it... sometimes the rules are dumb... but they are what they are and I choose to follow them. I'm not trying to be a jerk about it.
2. Venmo, PayPal, etc do not allow me to accept payment for the transfer of a firearm... I will accept a USPS money order. I've bought and sold a number of firearms on this and other forums over the years, and a mailed money order with tracking and signature required has been effective and safe. Certainly not convenient, but it works. HOWEVER, there is nothing I see in the venmo terms and conditions to prevent me from taking payment for something else related to the purchase; ie a part like a muzzlebrake, or the keyed trigger guard, or the shipping cost, etc. So, I will ask you to venmo me $200 to cover the cost of the shipping, the box, the muzzlebrake, the instruction manuals, the trigger lock, etc. This $200 will go towards the total $1675, so you would then just send me the difference of $1475 via the money order. The moment you get me the $200 venmo payment is when I would consider the rifle "sold pending funds".
3. When I take the rifle in to my FFL to have them ship it to your FFL, they will need your FFL to provide their shipping address and license info. If you can get that for me beforehand, it can save some time, but I would also need to give my ffl an email address and phone number for your ffl, as they always want to verify the info. In the past, my FFL has usually gotten the firearm in the mail within a day or two of when I drop it off. Then it will be up to you to check in with your FFL to see when it's delivered. And I can have my ffl get me a tracking number so you can monitor it that way as well.
