The ASM-DT is a Russian prototype folding-stock underwater firearm. It emerged in the 1990s.

The key improvement of the ASM-DT is that it uses a 5.45 mm rifled barrel with relatively shallow rifling, which allows to fire both standard 5.45 x 39 spin-stabilized ammunition, and modified underwater hydrodynamically stabilized ammunition, which is also based on 5.45 x39 case, with long projectile of about 5.4 mm in diameter.

The ASM-DT is a dual-medium assault rifle with two barrels for different purposes; a smoothbore barrel for use underwater and a rifled barrel for use above water. The rifled barrel has some grooves to expel gases when firing quickly to prevent the barrel from bursting.
