What is knife on rifle?

A knife on a rifle is usually mounted on the barrel of the rifle. It is a multifunctional tool that can serve several purposes. It enables the shooter to quickly switch between a knife and a firearm during close quarters combat situations. The knife can also be used to cut through brush, open cans, and perform other survival tasks. Knives mounted on rifles are also commonly used in hunting, as they make it easier to skin and prepare the animal after it has been taken down. Additionally, some special operations forces use knives mounted on their rifles as a backup weapon in case their primary weapon fails or runs out of ammunition.
