FIELD: weapons and ammunition.
SUBSTANCE: invention relates to identification of firing arm barrels by traces on discharged bullet. To identify rifling firing arm, marking element is made on barrel bore inner side to make individual traces on discharged bullet. Aforesaid marking element represents arbitrary change of micro relief in two and more barrel zones by multi-mode laser radiation, while additional marking element makes the distance between the zones of laser radiation effect and local change in micro relief in laser build-up of inhomogeneous paste.
EFFECT: reliable identification of firing arms including those with polygonal rifling grooves.
