Ballistics Advantage AR-15 5.56 Barrel

The Ballistics Advantage brand is known for offering a wide variety of quality products. This barrel proves itself to be no exception.

The finish is a newer type that claims to have the advantage of chrome without the accuracy issues.

Factors to consider when looking for an AR-15 barrel

Before you decide on the barrel for your own use, there are some factors that you need to consider. This will determine whether or not if an barrel you’re looking at is actually going to fit you perfectly. Here are some factors that past buyers have considered when buying their barrels:

Chrome Or Stainless Steel

These are two of the most important materials that are used to craft barrels. The chrome is typically found on the inside of the barrel to ensure that it is resistant to corrosion. It is imperative that you should limit your search to barrels that have this chrome lining on the inside. This guarantees that your barrel will last a long time, no matter how many rounds it fires off.

The lifespan of these barrels will typically be a longer period of time for chrome lined barrels. However, the lifespan of a "short-lived" barrel is said to be around 8 to 10 years in length. Stainless steel barrels are used for long-range shots, so if you're using an AR-15 for that purpose, a stainless steel barrel will be a perfect choice.


The profile is defined as the shape of the barrel. This shape affects the weight and in turn, will affect the gun’s overall weight. The most common barrel profiles include pencil, M4 Government, and Recce. The barrels with heavy profiles offer enough thermal mass to absorb and resist a lot of heat during full auto shooting. Pencil barrels are lighter and suitable for single shot or semi-automatic shooting. A Recce (which is a military term for reconnaissance) falls more on the heavier side with a mid-length gas system. The M4 is a mixture of both the lightweight and heavyweight barrels. It’s lightweight under the handguard and thickens just before the gas port.


Finding the AR-15 barrel doesn’t have to be a challenge. If you know what you’re looking for and know what the factors to consider, you won’t have a hard time figuring out which barrel is best for you. Be sure to check each review carefully. Always do your in-depth research if one barrel appears to stand out as your favorite.
