As of Oct 27th, 2025.

Alaska is green, Hawaii is red. Colorado is only banned in specific counties. But I only had polygon data for the whole state.

Yellow means there is either a Bump Stock Ban, or other “Trigger Activator” Ban that specifically mentions “recoil” as the mode over operation.

The litmus test for legality there is whether or not arresting the recoil (bolting rifle to table, etc) would disable the functionality (i.e.) like a bump stock.

I’m by no means an authority on this, but from my research this is what I got.

Feel free to comment/challenge any states, and I'll update this post.
