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.
NJ here.
Yes, our bump stock ban is probably worded as such that it would include FRTs. No manufacturer or retailer I've seen will ship one here. You could probably buy one in PA, but nobody wants to be the guinea pig dragged through the courts for good reason. You'd have nowhere to shoot it regardless.
Our opinion on that is that "recoil" is the mode of operation. Hence why we sell to NJ.
If you were to bolt the rifle to a bench rest or similar - a bump stock would not work, but a super safety would.
Recoil is the impulse of the whole rifle backwards - not the gas system pushing the BCG backwards.
