Experimental Analysis of Characteristics of Small Arms Weapon with 9×39 mm Armor-Piercing Subsonic Ammunition System
The paper presents research conducted on the current VSS Vintorez rifle and the concept of an improved modular weapon system on the AM20 platform with a subsonic system of ammunition 9×39 mm. The test was conducted with the aim of comparing the characteristics of the weapon required for special tasks. The determination of the characteristics of the existing weapon and the concept of an improved modular system on the AM20 platform was carried out through experimental tests. The test was conducted to compare the accuracy and precision of the weapon with a subsonic ammunition system with a 9×39 mm bullet. The tested automatic weapon systems were realized at 100 m under standard conditions, with the appropriate number of shots (ten groups of ten shots each with identical ammunition). The emphasis during the testing was on measuring the muzzle velocity, accuracy, and precision, according to standard testing methods. The results of experimental tests showed a high level of accuracy and precision and an adequate level of initial velocity values. Based on the conducted comparative analysis of accuracy and precision, the possibilities of use in the implementation of tactical tasks in urban environments for the proposed concept of an improved modular system on the AM20 platform were given.
