A device designed for the AR-15 platform that simulates automatic fire while remaining within the bounds of legal semi-automatic operation is available in the market. These devices typically work by harnessing the recoil or other mechanical forces to reset the trigger rapidly, allowing for a faster rate of fire than traditional semi-automatic triggers but without actually converting the firearm to fully automatic operation. A binary trigger is one example of such a device; it fires one round when the trigger is pulled and another when the trigger is released. While functionally different from a true automatic trigger, these devices offer a similar user experience.
The primary draw for such devices lies in the ability to increase the speed of target engagement while maintaining legal compliance. This is particularly attractive to competitive shooters, as it can offer a competitive edge. The legality of these devices is often a subject of debate and varies by jurisdiction. Understanding local and federal laws before purchasing or using such a device is crucial. The history of these devices is intertwined with the ongoing discussion surrounding firearm regulation and the balance between the rights of gun owners and public safety concerns.
