The website, called "Migrantenschreck" (Migrant Shock), was run by a company based in Budapest and exported Hungarian weapons to hundreds of customers across Germany.
According to Die Zeit, the website was run by Mario Rönsch, who was also the brains behind another controversial site called Anonymous.Kollektiv. The anti-immigration site gained two million Facebook likes before it closed down in May.
In June, Migrantenschreck advertised its wares in an email to subscribers of the magazine "Compact," popular with supporters of the right-wing political party Alternative for Germany (AfD). However, in October Compact sought to distance itself from the site, and called it "criminal."
Nevertheless, between May and December 2016, Migrantenschreck sold 110,000 euros worth of weapons to at least 198 customers across Germany. The most popular product was an air revolver which cost 349 euros ($376).

Last month Die Zeit published a map illustrating the store's weapons deliveries across Germany.
The weapons are capable of shooting rubber bullets with a maximum energy of 80 or 120 joules, far in excess of the 7.5 joules allowed under German law. Such force can cause serious injury or even death if fired at close range.
On January 24, German police raided the living premises of 29 people in 11 German states suspected of buying weapons and ammunition from Migrantenschreck, and discovered 42 illegal weapons.
Since then, Migrantenschreck has not taken any more orders, and on Thursday the controversial website was offline.
