I mean my membership is only a few days old there but that's because I didn't even know they were a thing. Stumbled upon it by a Google search lol same hereI sold and bought at Texas Gun Trader.
There are some things that I look out for.
Sellers Membership Date - A couple days old
Location - Out of state
Price - if it’s too good to be true, then it probably is
If I see any of the above, then it’s most likely a spammer, (selling your phone number)or a scammer. I’ve met some like minded people over there.
