Physics of Rifle Recoil

The reaction of the missing number is often called "kick", but it is due to the physical characteristics during work. However, this can often be uncomfortable for the shooter and is often undesirable as it can degrade accuracy. The purpose of this page is to discuss the physics related to the rifle reaction to tackle various ways to minimize it. Newton's First Law of Motion and Second Law of Motion explain the reaction of a rifle most simply. When the rifle is fired, force is applied to bullets fired forward.

The physical principles that influence the reaction of installed guns and cannons are equally applicable to hand-held guns. However, the shooter's body is responsible for the gun and must consume gun bouncing momentum for longer than bullet bullet movement time to avoid hurting the shooter. For this purpose, hands, arms and shoulders have considerable strength and elasticity to a practical limit. Nevertheless, the "perceived" reaction limit depends on the size of the body, the use of reaction filling, the tolerance of personal pain, the weight of the gun, and whether or not the use of a rebound damping system and muzzle brake is used, It depends on the shooter. Therefore, despite direct physics, the reaction safety standards for small weapons are still difficult.

With small weapons, the way the shooter senses kickbacks and kicks may have a significant impact on the shooter's experience and performance. For example, it is said that guns that behave like scorpions are said to be close to fear and shooters may expect a rebound and anticipated retreat when shooting is released. This will cause the shooter to pull the trigger rather than pulling the trigger smoothly. And jagged motion almost certainly hinders gun alignment and may cause mistakes. The shooter may be physically injured by shooting weapons beyond the bounce that the body can safely absorb or repel; it may be struck by the scope of the rifle shoulder , Damage to soft tissues such as wrists, hands, etc., or these results vary from person to person
