Developed specifically for the Scorpion EVO this model of Eclipse has 18mm threads and is actually the first in our line of "Shadow" flash hiders despite the name. Three shorter straight prongs make the device more compact while still giving plenty of flash suppression for the 9mm cartridge. Six detent notches allow the muzzle device to thread down as much as possible, and the device is marked "MA USA" to denote USA manufacture for 922r compliance.
