Multi-purpose combat rifle

The present invention relates to weapon systems, and more particularly to a multi-purpose combat rifle that is adaptable to a variety of terrains, distances, and various types of combat and mission requirements.

The so-called combat rifle usually refers to a combat rifle with a selectable launch mode, a relatively long-range firing accuracy, and a modular operation. According to mission requirements and combat types, it can be divided into standard type, short assault type and sniper type. Its modular design allows quick change of barrels, calibers, guards, grips and stocks, and combines various optical sights, night vision goggles and 20 mm grenade launchers to meet multi-caliber, all-weather operations. The needs of the mission are suitable for use in combat environments such as towns and jungles. For paratroopers, combat rifles must be more portable during the parachute jump and can be immediately put into combat after reaching the ground.

In general, operational needs can be divided into the following three types:

1. Short-range counterattack: The combat distance is about 200 meters, and the gun type is short assault type. The focus of the operation is to provide suppression firepower.

2. Medium-range assault: The combat distance is about 300 meters, and the gun type is standard. The focus of the operation is on precision, and it can still provide suppression firepower.

3. Remote sniper: The combat distance is about 300-600 meters, and the gun type is sniper type. The focus of the operation is to implement precise aiming and accurately hit the target.

For the above reasons, we hope to design a multi-purpose combat rifle that can adapt to various terrains, distances and various types of combat and mission requirements.
