The PKS machine gun, firing bursts from its tripod with fixed traversing and elevation mechanisms, as a medium machine gun has the following accuracy of fire: mean deviation of at a range of , cm at , and at . The Russian and other European militaries use a circular error probable method that assumes a 50% hit probability (R50) and cannot be converted and is not comparable to US military methods for determining small arms accuracy. When the R50 results are doubled the hit probability increases to 93.7%.
