D.C. Attorney General Karl Racine has filed a consumer protection lawsuit against a gun manufacturer, accusing the company of flooding the District with untraceable firearms.

Police in the District have confiscated 250 untraceable firearms since 2017 — 208 of which have come from kits sold by Nevada-based gun manufacturer Polymer80, according to a statement from Racine’s office.

Polymer80 sells untraceable, partially assembled semi-automatic rifle and handgun kits online. The firearms are commonly referred to as “ghost guns” because they lack serial numbers that make it difficult for law enforcement to trace back to individuals.

The suit accuses Polymer80 of misleading customers into believing their firearm parts are legal in the District once assembled. Racine said in a statement that the Metropolitan Police Department has recovered 106 ghost guns in the District since January.

“These ghost guns are used to commit violent crimes and have been used in several homicides in the District of Columbia,” Racine said.

D.C. Mayor Muriel Bowser signed legislation in March to temporarily ban kits used to assemble firearms like the ones sold by Polymer80 after MPD experienced a surge in the recovery of guns without serial numbers last year. In a joint statement with Ward 6 Councilmember Charles Allen, who chairs the judiciary and public safety committee, Bowser said difficult-to-trace firearms reflect the “real trauma and pain” that D.C. residents face because of gun violence.

“This critical legislation will help us stop the proliferation of untraceable guns and guns that people buy online and build at home in an attempt to get around the District’s carefully crafted, common sense gun laws,” the statement said.

The lawsuit alleges that Polymer80 misleads consumers by advertising its products “without restriction” to customers in the District, failing to alert them that the products may violate local law.

Polymer80 makes its “Buy, Build, Shoot” kits available online and they include everything needed to assemble a rifle or handgun in a single package. However, the parts within the kit lack unique manufacturer or dealer numbers. The suit alleges that the company falsely claimed that its firearms were legal because they are not shipped fully assembled, but they are considered firearms under District law.

Polymer80 also doesn’t disclose on its website that it is not licensed to sell firearms in D.C. According to a statement from Racine, the company is prohibited from even obtaining a commercial license to sell firearms in the District because it sells “assault weapons,” including the AR-15 and other semi-automatic rifles illegal in D.C. The attorney general’s suit also claims the company violates the 10-day mandatory waiting period for firearm purchases.

Racine intends to use the District’s Consumer Protection Procedures Act to support the lawsuit. The law prohibits deceptive and unlawful business practices that could potentially harm consumers.

Polymer80 did not immediately respond to requests for comment.
