Origin
The APS underwater assault rifle is a underwater firearm designed by the Soviet Union in the early 1970s. It was adopted in 1975. It is made by the Tula Arms Plant in Russia. It is exported by Rosoboronexport. Underwater, ordinary-shaped bullets are inaccurate and very short-range. The APS fires a steel bolt caliber 5.66 mm (specially designed for this rifle and is often mistaken as 5.56 mm) and 120 mm (4.75 in) long. Its magazine holds 26 cartridges. The APS's barrel is not rifled; the fired projectile is kept in line by hydrodynamic effects. As a result, the APS is somewhat inaccurate when fired out of water.
