What is an Akins accelerator?

In 2002, one of the first bump stock-type devices, the Akins Accelerator invented by Bill Akins, was deemed by the US Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to not be a " machinegun ". The Akins Accelerator used an internal spring to force the firearm forward to re-make contact with the trigger finger after the recoil of the previous shot pushed the firearm rearward. The ATF interpreted a "single function of the trigger" to mean a "single movement of the trigger", and since the trigger moved for each shot, the Akins Accelerator was deemed to not be a machinegun. Later, in 2006, the ATF reversed course and reinterpreted the language to mean "single pull of the trigger", which reclassified the Akins Accelerator as a machinegun. The Eleventh Circuit Court of Appeals upheld the new interpretation in February 2009.
