Can military rifles shoot underwater?

Ordinary rifles can't shoot normally under water, and their range and trajectory will be affected by water. For example, M 16 and M4, if filmed underwater, will explode because the air duct is blocked by water. There is a special underwater shooting rifle: Russian Aps underwater assault rifle, which fires bullets different from ordinary rifle bullets. The warhead adopts a special long rod-shaped flat-topped warhead, including ASM-DT amphibious assault rifle, Mgts underwater rifle bullets and land 5.45mm rifle bullets. Ads amphibious assault rifle can be used underwater and on land, using Psp bombs.
