Assault Weapons Bans by State

State laws that ban or restrict firearms the statute defines as 'assault weapons' (definitions differ by state). Most bans let people keep guns they owned before the ban. The U.S. Supreme Court has agreed to hear challenges to such bans (decision expected 2027).

Source: State statutes (official legislature code sites), state police / attorney general pages and court orders; citation for every item is in the popup. Compiled by Map the Block, law as of 2026-10-06

Coverage: All 50 states and DC

How it was checked: Drafted from the statutes, then checked against official pages fetched for this layer (state code sites, state police and county pages, court orders, bill-status pages): 80 automated text checks passed across 29 states and 12 more items were settled by reading the page; 7 draft values were corrected that way (WV permitless age, CT long-gun age, MN waiting period, NM injunction scope, ND and MT carry rules, WA training requirement). All states were also compared item by item with a separate summary table (283 comparisons): 3 differences remain, each explained in the report. RAND's database and NCSL refused or block AI crawlers, so neither was used; CA, HI and DC code sites refused or block us, so those states rest on statute citations plus the table cross-check.
