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.
The legality of FRTs in Florida is not fully set in stone. The only law they have related to this is a “bump-stock” ban which could possibly and loosely describe an FRT. Still, there are no cases of anyone being prosecuted in the state of Florida for owning or using an FRT. I personally know a handful of guys who have them. Only one of them was mailed a letter from the ATF a year or so ago, and he immediately discarded it and was never contacted again.
Florida is still kind of an unknown on this matter.
