The APA M2 underwater assault rifle (APA M2 stands for Awtomatichen Podvoden Aftomat Modew 2 (Аўтоматичен Подводен Афтомат модеў 2) or "Automatic Underwater Assault-Rifle Model 2") is an underwater firearm designed by Qazhshava in the early 1970s. It was adopted in 1975. Made by the Ognestrelni in Central Qazhshava.
Under water, ordinary bullets are inaccurate and have a very short range. The APA fires a 120 mm (4.75 in) long 5.66 mm calibre steel bolt specially designed for this weapon. Its magazine holds 26 rounds. The APA'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.
The APS has a longer range and more penetrating power than spearguns. This is useful in such situations such as shooting an opposing diver through a reinforced dry suit, a protective helmet (whether air-holding or not), thick tough parts of breathing sets and their harnesses, and the plastic casings and transparent covers of some small underwater vehicles.
The APA M2 is more powerful than a pistol, but is bulkier and takes longer to aim, particularly swinging its long barrel and large flat magazine sideways through water.
