I initiated a trade year’s ago w/ a fellow ‘Hider. We exchanged cell numbers, shot the breeze & negotiated terms. We put EVERYTHING in writing via PMs here on the Hide. There was 3K+ worth of rifle changing hands each way, so not a small investment. Tgere was also a record if anything went sideways.
We shipped rifles cross country to our respective FFLs. We both got exactly what was promised & all was well. Almost five years later I still keep in touch w/ the guy now & then.
I’ve bought, sold & traded about half dozen times over the years on this site & everyone has been above board. Offer tracking numbers, take plenty of pics of the item(s) showing the best & worst if said item. Honesty is very important here. The best advice I can offer is maintain your integrity as well as good comms.
