The Russians have been working on an underwater weapons system since the 60's

Next line of development, almost unique to the Soviet armed forces, is the underwater firearms and ammunition for these. Initially developed during late sixties, underwater cartridges propelled the long and slim drag-stabilized bullets, and were used in four-barreled SPP-1 break-open pistols. To achieve better loading and extraction, the bottlenecked brass cartridges were rimmed and loaded using special flat clips, which held all four rounds together. Both primer pockets and case necks were sealed against the water, and the steel bullets were covered by special lacquer coating. Initially satisfied with the pistol, Special Forces elements of the Soviet Navy requested further development and by the mid-1970s soviet designers brought in an unique underwater assault rifle, the APS (which, in fact, was a smoothbore weapon). This weapon used cartridges, externally similar to earlier SPS pistol ammunition, but based on the standard 5.45x39 M74 cases. This “rifle” ammunition is available in two basic forms, MPS “ball” and MPST “tracer”. Both APS underwater automatic weapon and SPP-1M underwater pistol are still in use by Russian navy, as well as offered for export.
The Video demonstration is in Russian but you get the idea
