The ATAMAN ML15 pneumatic PCP rifle is a simplified version of the ATAMAN M2R series of rifles. The main difference is the direct current, which replaced the expensive gearbox and made the products less dependent on temperature conditions (trouble-free operation in low temperature conditions). The barrel of the ML15 rifle is made of high-quality barrel blank from the company Lothar Walther (Germany). The high-pressure tank, which is the rifle's energy source, has a volume of 250 cm3 and an operating pressure of 220bar. The pressure gauge for monitoring the air pressure in the tank, unlike the M2R, is located on the side, not far from the USM.
