The nature and morphology of distribution of gunshot residue on targets' surfaces made it possible to establish close range firing zones. The nature in which soot is deposited during shot under the conditions of point-blank range and in the first zone of close range (up to 8 cm) allows to establish the position of weapon's transverse plane relative to the target basing on a specific blowout of a gas-powder jet from special design of flame arrestor. The performed experimental shooting from hunting self-loading Steyr Mannlicher AUG-Z3 carbine made it possible to determine the metric and morphological characteristics of the close range firing zones: 1 zone is equal a distance up to 8 cm; 2 zone - up to 30 cm; 3 zone - up to 100 cm from muzzle of weapon. The design features of Steyr Mannlicher AUG-Z3 carbine's flame arrestor allow to identify the type of weapon according to the morphological pattern of target's damage. The complex of obtained data makes it possible to determine the firing distance with high accuracy.
