An AR-15 lower receiver from 80percentarms.com is always offered at an affordable price. However, if you are getting into this hobby and looking to buy your first AR-15 rifle, you should know about its parts and functions to ensure gun safety. Following is the guideline on all its parts.

1. Mechanism

Before talking about the parts, you should know how AR-15 rifles work. Direct impingement is a gas system that uses the gas lit by the gunpowder and redirects it to the bolt, allowing the gun to fire the bullet. AR-15 rifles are unique because they don’t require additional components for the gas action, unlike other gas-powered weapons. This makes the rifle lightweight and easy to control during heavy firing sessions. The mechanism also prevents the rifle from overheating, thus increasing its performance under extreme conditions.

2. Barrel

The length of the barrel and subsequent spin of the bullet determines the performance of an AR-15 rifle. The standard length of the barrel is 16 inches, and it allows the bullet to complete a rotation every eight inches. The barrel’s length determines the range at which an AR-15 can hit a target, whereas the accuracy relies on the rotations of a bullet before it leaves the barrel. Barrels are directly attached to the lower receiver part of the rifle and can easily be detached for customizations or cleaning.

3. Magazine

A standard magazine of an AR-15 rifle holds 30 rounds but can be customized according to your local laws and needs. There are commonly two bullet calibers used in an AR-15; 5.56mm and .233mm. The 5.56mm is also called NATO caliber as it is widely used by their forces, whereas .233mm is also known as Remington caliber. Both calibers can be used in the gun; however, you need to take special precautions as there is a chance of an accident. You can avoid this by using specified cartridges for both calibers, as 5.56mm has a high-pressure one then a .233mm one.

4. Bolt

This is an essential component of an AR-15 rifle; the bolt closes the magazine once the bullet is loaded into the chamber. The bolt allows the gun to withstand high pressures once the gunpowder is ignited. Any faults in the bolt can jam or blast the guns in your hands, leading to severe injuries.

5. Attachments

There are additional attachments that can massively increase the performance of your rifle. You can add an iron sight to enhance the accuracy or change the barrel to fire at a long distance. Similarly, you can change triggers, stocks, and magazine sizes to suit your needs.
