Bill in U.S. House seeks mandatory serial numbers for 3D-printed and unmarked guns

A legislative proposal from U.S. Rep. Dave Min in the U.S. House would boost oversight of firearms by mandating serial numbers for certain unmarked and additively manufactured guns, according to the U.S. Congress.

H.R.8059 was introduced on March 24, 2026, during the 119th Congress’ regular session. Below is a summary based on the actual bill text, including explanations for clarity.

The bill requires serialization of firearms created using additive manufacturing and those in the possession of federally licensed dealers and gunsmiths that are unmarked. Violations could result in civil penalties of up to $10,000 for an initial offense, with additional criminal penalties possible for repeat violations. The measure amends current law to consider specified firearm assembly kits as firearms and directs licensed dealers to engrave serial numbers on any unmarked firearms received. It also offers a tax credit to licensed firearm dealers to help offset serialization expenses. Existing state laws are not affected. The reform would take effect 180 days after enactment.

Rep. Dave Min (Democrat-CA-47th District) sponsors the bill, along with co-sponsors Rep. Wesley Bell (Democrat-CA-1st District), Rep. Josh Gottheimer (Democrat-CA-5th District), Rep. Sylvia R. Garcia (Democrat-CA-29th District), and five others.

Rep. Min has introduced another 17 bills since the current congressional session began.

Congressional bills may be introduced in either the U.S. House of Representatives or the U.S. Senate, except for revenue measures, which originate in the House. Following introduction, bills proceed to committee review, hearings, amendments and debate before reaching a vote in each body. Identical approved versions proceed to the president for signature or veto. Congress meets in two-year terms, with each term numbered and divided into two sessions. The process and official bill records are administered by the U.S. Congress and posted on Congress.gov.
