We can start by passing an assault weapons ban and background checks...
Pass universal background checks for gun purchases.

Evidence
H.R.18 states: "To require a background check for every firearm sale." The introduced bill lists "Mr. Moulton" among the Members introducing the bill and would make it unlawful for unlicensed persons to transfer firearms unless a licensed dealer first takes possession for a background check.
Congress.gov lists H.R.18 as introduced June 10, 2025, referred to the House Committee on the Judiciary, and states: "This bill has the status Introduced."
Congress.gov summarizes H.R.8 as establishing new background check requirements for firearm transfers between private parties. It states the bill passed the House 227-203 on March 11, 2021, but the latest action was Senate placement on the legislative calendar and the bill status was "Passed House."
The H.R.8 cosponsors page lists "Rep. Moulton, Seth [D-MA-6]" as a cosponsor dated March 8, 2021.
The House Clerk records Roll Call 75 on H.R.8, the Bipartisan Background Checks Act, as passed 227-203. The vote table lists "Moulton Democratic Massachusetts MA Yea."
Congress.gov states S.2938 became Public Law No. 117-159 on June 25, 2022. The CRS summary says the act made changes to federal firearms laws, including expanding background check requirements, and specifically expanded checks for purchasers ages 18 to 21 and revised the definition of being engaged in the business as a firearms dealer.
Assessments
Moulton materially supported universal-background-check legislation, including cosponsoring and voting for H.R.8 in 2021 and joining H.R.18 in 2025. But no federal universal background check requirement for all gun purchases/private transfers had become law by July 2, 2026. The 2022 Bipartisan Safer Communities Act expanded some background-check rules, but it was narrower than the promised universal checks. Because he made serious legislative efforts without delivering the promised outcome, this is not fulfilled but earns an effort badge.
