ABSTRACT:
A flash suppressor of the open prong type having a twist in its structure formed of alternating grooves and flutes or prongs provides a highly effective flash suppression for small and medium caliber weapons and especially for automatic weapons and machine guns when placed on the end of their barrels. The orientation of the direction of the twist of the structure is in a direction opposite to the direction of the rifling in its firearm barrel. Various objective laboratory tests and subjective user evaluation on its performance prove out its effectiveness in terms of mitigating visible flash on shorten machine gun barrels as well as standard full length barrels used in critical helicopter black out operations using night vision equipment. In addition, precise aiming of a weapon equipped with the inventive flash suppressor exhibits lower dispersion of actual projectile impact compared to conventional flash suppressors.
