So I have finally started to get the funds together to start buying parts for my first rifle build. I have found some things in the for sale forums here that I would like but I have never spent a large amount of money online with a private seller. My question is what method do you use to make sure you don't get hosed buying online? I would not worry as much if the sellers had people vouching for them or a ton of posts but what if they have neither? Any help would be much appreciated. Thanks!
