Underwater rifle

The paper is focused on the establishment of a mathematical model describing the motion of bolt carrier for the amphibious rifles when shooting underwater in the period of the projectile moving to the position of the gas port. Besides, the conditions for bolt carrier motion are studied. The object of this paper is the bolt carrier assembly of the 5.56 mm amphibious rifle according to the designing of the research project of the ministry of defense 2017.73.034. The result of this research indicates that: for the 5.

The paper is focused on study of the interior ballistics model of amphibious rifle when firing underwater based on the standard interior ballistics of automatic rifle using gas operated principle. The presented mathematical model is validated and experimentally verified for the 5.56 mm underwater projectile fired from the 5.56 mm amphibious rifle. The result of this research can be applied to design the underwater ammunition, underwater rifle and amphibious rifle.
