The XM556 Microgun is a weapon currently under development by Texas-based company Empty Shell, LLC. The XM556 Microgun is designed as a defensive suppression weapon chambered for the 5.56mm NATO cartridge, and is based in concept and design on the M134 gatling gun system. Profile pictures on Empty Shell’s website show the XM556 Microgun as being shorter in length than a carbine-length AR-15 and even a PS90, so if anything else, it has a pretty compact profile going for it.
Stay tuned for more info on this weapon as it becomes available.
