The APS has a similar shape to the AK-47 and is simply designed with only 42 components. APS fired 5 shells of 66 x 120mm darts from a 26-bullet ammunition box, firing at 600 rounds per minute, both underwater or on land.
Just like the SPP-1, the APS gun has a smooth barrel so it doesn't work well on the shore.

According to the declaration of Russian weapons manufacturer KPB in 2013, they successfully built the ADS dual-use fast assault rifle. This gun is effective both in water and on shore.
When transferring combat environments, users only need to transfer the relay box from the traditional ammunition container to the specially designed ammunition box.
When firing under water, an air bubble will surround the bullet . The mechanism of bubble-making around ADS bullets is the mechanism used to design Shkval torpedoes that can travel at speeds of up to 370 km / h.
Under water, ADS guns have an optimal range of about 25m at a depth of 30m and a depth of 20m is 18m. ADS weighs 4.6kg and has a 40mm grenade launcher function, shooting 5 bullets of 45 x 39 mm. When on shore, ADS can fire up to 800 capsules per minute at a range of 500m.
The effectiveness and accuracy of the ADS rifle is judged not to be inferior, even higher than the legendary AK-47.
