Water is damaging to most historic objects. For historic firearms, water will cause corrosion of metal components, swell wood, and encourage mold growth. Water will also cause antler, bone, and ivory to swell. [9] Animal rawhide and semi-tanned leather will absorb moisture and will be at risk for mold growth. It could also become discolored.

For larger guns, the cooling periods were longer and more water was used. After cooling the gun, the machining process began. The bore was bored out to proper size, the exterior was turned smooth, the trunnions were turned on a trunnion lathe, and a vent was drilled.

The APS can operate on land, but its effective range does not exceed 50 metres, and the rifle's lifetime drops to 180 shots in air from 2,000 shots underwater. Therefore, they mostly carried a SPP-1 pistol for self-defence under water and an AK-74 to fight on land. At the end of the 1980s the ASM-DT amphibious rifle was developed.
