GAO agents attempted to purchase firearms from Dark Web and Surface Web marketplaces. Agents made seven attempts to purchase firearms on the Dark Web. In these attempts, agents did not disclose any information about whether they were prohibited from possessing a firearm. Of these seven attempts, two on a Dark Web marketplace were successful. Specifically, GAO agents purchased and received an AR-15 rifle and an Uzi that the seller said was modified so that it would fire automatically. GAO provided referral letters to applicable law-enforcement agencies for these purchases to inform any ongoing investigations.
Tests performed on the Surface Web demonstrated that private sellers GAO contacted on gun forums and other classified ads were unwilling to sell a firearm to an individual who appeared to be prohibited from possessing a firearm. Of the 72 attempts agents made to purchase firearms on the Surface Web, 56 sellers refused to complete a transaction: 29 sellers stated they would not ship a firearm and 27 refused after the disclosure of the undercover identities’ stated prohibited status. Furthermore, in 5 of these 72 attempts, the accounts GAO set up were frozen by the websites, which prevented the agents from using the forums and attempting to make a purchase.
Cliff's' notes: GAO tried 72 times to buy firearms on the normal internet using scenarios that would reveal prohibited person information and everyone of them failed.
The GAO also got scammed twice on the "Surface Web", sending $$ but receiving no firearm.
