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.
I am curious if New Mexico intends to apply HB0038 UNLAWFUL POSSESSION OF A WEAPON CONVERSION DEVICE to FRTs, because they didn’t use the standard definition for machinegun. For the federal definition, it was determined in carghill that “function of the trigger” related to the trigger itself moving rather than the squeeze of the trigger finger, but this NM definition sounds like it is focused on the action of the finger…
“(1) “fully automatic weapon” means a weapon that shoots, is designed to shoot or can be readily restored to shoot more than one shot, without manual reloading, by a single and continuous held pull of the trigger;”
