The lawsuit alleges that the companies knew they were contributing to illegal arms trafficking, which has been linked to many deaths.
Officials say Mexico is seeking as much as $10bn (£7.2bn) in compensation, though any amount would be decided by the court.
The companies have not yet commented.
They include Smith & Wesson and Barrett Firearms, among others. The BBC has contacted both companies for comment.
The lawsuit was filed on Wednesday in the US state of Massachusetts.
The gun manufacturers “are conscious of the fact that their products are trafficked and used in illicit activities against the civilian population and authorities of Mexico”, the Foreign Ministry said in a document related to the lawsuit, according to reports.
The Mexican government estimates that some 70% of weapons trafficked to the country come from the US, according to the Associated Press news agency. In 2019 alone, more than 17,000 murders in Mexico were linked to trafficked weapons.
One official told reporters the damage caused by trafficked guns would be equal to around 1.7% of Mexico’s gross domestic product (GDP).
Speaking at a news conference on Wednesday, Foreign Minister Marcelo Ebrard said: “We are going to win the trial and we are going to drastically reduce illicit arms trafficking to Mexico.”
But experts have cast doubt on Mexico’s likelihood of success with the lawsuit.
Lorenzo Meyer, an emeritus professor at the College of Mexico, told AFP news agency that US law “makes it almost impossible for gun manufacturers to be held responsible” for the illegal trade.
