The AR-15 rifle has gained a great deal of popularity over the past few decades, and there are plenty of reasons why many gun owners prefer it to other rifles and handguns. However, one thing that causes some AR-15 owners to put off using their guns as often as they’d like is the fact that an ar 15 parts needs to be properly maintained and upgraded regularly in order to keep up with the latest technology and remain effective in high-stress situations.


The AR-15 is a popular rifle that is perfect for home defense, hunting, and target shooting. The best part about the AR-15 is that you can change the parts in order to tailor it to your specific needs. In this post, I’ll discuss how you can upgrade your AR-15 using aftermarket parts in order to improve performance.

Upper Receiver

The upper receiver is the part of the AR-15 that houses the bolt and barrel assembly. It also houses the charging handle, which is used to load a round into the chamber. Upgrading this part will give you better performance in terms of accuracy and durability.
One thing that you can upgrade on your upper receiver are your sights, which are what you use to aim and shoot at your target.


A barrel is the part of a rifle or handgun that contains the grooves, lands, and ports that force the bullet out of the gun. Barrels are manufactured in a variety of lengths, thicknesses, finishes, and styles.

Gas System

One of the most important upgrades you can make to your AR-15 is the gas system. The gas system controls how much pressure builds up before the bolt carrier releases and cycles a new round. There are two main types of gas systems: direct impingement and piston, each with their own pros and cons. Direct impingement is more popular than piston, but it has drawbacks such as reliability in cold weather.

Muzzle Device

A muzzle device is a type of device which attaches to the muzzle and projects the propellant gases forward, away from the direction of fire. It may take the form of a flash suppressor, sound suppressor, or muzzle brake. The most common use is as a flash suppressor.


The AR-15 is a rifle designed by Eugene Stoner and has been in production since the 1950s. Originally manufactured by ArmaLite, it was later sold to Colt and became the M16. Today, the AR-15 can be found in many variants from Ruger, Smith & Wesson, Remington, DPMS, or Bushmaster.


The AR-15 is a powerful and versatile rifle that can be easily modified with the right parts. I recommend regularly upgrading your parts so you’re always ready for whatever comes your way.
