The AR-15 is a semi-automatic rifle that is made up of several different parts. Here are the main components of an AR-15:
- Upper receiver: This is the part of the gun that houses the bolt carrier group, barrel, and firing mechanism. It sits on top of the lower receiver and is responsible for firing the rounds.
- Lower receiver: This is the part of the gun that holds the trigger, magazine, and stock. It sits below the upper receiver and is responsible for controlling the firing of the gun.
- Bolt carrier group: This is the part of the gun that moves back and forth to load, fire, and extract rounds. It consists of the bolt, bolt carrier, and firing pin.
- Barrel: This is the part of the gun that the bullet travels through after it is fired. The length and caliber of the barrel will determine the range and accuracy of the gun.
- Stock: This is the part of the gun that the shooter holds against their shoulder to steady the gun when firing. It can be adjustable or fixed in length.
- Magazine: This is the part of the gun that holds the rounds that are fed into the chamber. The capacity of the magazine will vary depending on the model.
- Handguard: This is the part of the gun that surrounds the barrel and provides a place for the shooter to hold onto the gun. It can be made of plastic, metal, or a combination of both.
- Sight: This is the part of the gun that helps the shooter aim at their target. It can be a simple iron sight or a more advanced optical sight.
- Muzzle: This is the part of the gun that the bullet exits from. It can be equipped with a variety of attachments, such as a flash suppressor or muzzle brake.
