Choosing the appropriate AR15 barrel profile is one of the most important decisions to make when building or customizing an AR-15. The shape and size of the barrel, as determined by the profile, can greatly affect the performance and functionality of the firearm.

Let’s take a look at the different AR-15 barrel profiles available and help you understand the pros and cons of each so you can make an informed decision. From heavier barrel profiles to lightweight pencil barrel profiles, we’ll cover it all.

Whether you’re a competitive shooter, a hunter, or just a hobbyist, this guide will help you choose the perfect barrel profile for your specific needs and goals.

AR Barrel Profiles Explained

The term “barrel profile” refers to the thickness of a barrel on an AR-15 style rifle, such as the Faxon Sentry 16” 5.56 Rifle. Different barrel profiles can impact the performance of the gun in various ways.

For instance, thinner barrels are lightweight and easy to handle, while thicker barrels provide more stability by adding weight to the front of the gun and can withstand more heat.

It’s essential to consider the trade-offs of different barrel options available in the market when making a choice.

Let’s now look at the different AR-15 barrel profiles to see what makes each one unique.

Gunner Profile

The Gunner profile is a blend of two of the best-performing profiles of all time, Gov’t and Pencil. 

Faxon’s Gunner profile combines the durability of the Gov’t profile with the weight savings and maneuverability of the Pencil profile.

The Gunner profile brings the rifle’s balance back towards the shooter’s body, limiting fatigue and allowing for shooting, training, or hunting all day long.

Government/SOCOM Profile

A SOCOM barrel for an AR-15 is designed differently from the standard M4/A2 barrel.

Instead of being consistently thick throughout, it has a thinner section past the gas block and a thicker section near the chamber. In addition, SOCOM barrels often have a slot for attaching a grenade launcher and provide a balance between strength and weight.

If you’re looking for a barrel that can handle sustained shooting while still being lightweight, a SOCOM profile barrel may be a good option for you.

Pencil Profile

The pencil barrel is the original profile for the AR-15, typically measuring 0.625 inches in diameter.

It is known for being slim and lightweight, making it easy to carry and handle. However, due to its thinness, it may overheat more quickly during rapid firing, leading to elastic deformation or warping, which can affect reliability and accuracy.

Unlike run-of-the-mill pencil barrels, Faxon Firearms barrels are properly heat-treated and stress-relieved to improve heat resistance and longevity.

The durability of this AR15 barrel profile is ideal for shooters with a light or medium shooting schedule.

AR Barrel Profiles: Finding Your Match

The barrel profile of an AR-15 rifle can greatly affect its overall performance and handling.

The three most common barrel profiles are the Gunner, Government, and Pencil. The Government/SOCOM profile is the thickest and heaviest option, providing the most stability and accuracy but also adding extra weight to the rifle.

The pencil profile is the thinnest and lightest option, making it easier to handle and carry, but sacrificing some stability and accuracy. The government profile is a balance between the two, offering a good compromise between weight and performance.

Ultimately, the choice of barrel profile will depend on the individual’s personal preferences and intended use of the rifle. Therefore, it is important to consider the trade-offs and choose the barrel profile that best suits your needs.

FINAL RULE ATF: Last week, the BATFE issued new guidance on the legality of 80% frame lowers like those manufactured by Polymer 80, Lone Wolf Arms, Nomad Defense, and Matrix Arms. It’s rarely a Good Thing when we have to report ATF news, and this time is no different.

ATF Changes its Mind. Again.

Once again, the Federal Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) has changed its mind. Remember how 80 percent frames and lowers were legal until Joe Biden’s ATF decided that they weren’t? You know, like the ATF always does.

That question was shaking out as part of the Vanderstok v. Garland case in federal court, with the ATF agreeing that the frames and receivers in question were indeed legal so long as they didn’t ship with “associated templates, jigs, molds, equipment, tools, instructions, guides, or marketing materials.”

So, basically, the frames and receivers are only firearms under the Gun Control Act (GCA) if they are packaged with those “non-firearm objects” (NFO). Strange, but okay. Companies had already incorporated that change and were continuing to ship their products. NFO sold separately.

Then, out of the blue, ATF dropped a new rule on FFLs by way of a December 27 open letter. The letter stated that “these partially complete pistol frames are ‘frames’ and ‘firearms’ as defined in the GCA and its implementing regulations.” Even if they don’t include the NFO items.

ATF bases this change on the definition of the word “readily,” as in whether these frames can be “readily converted” to fully functioning firearms.

Here’s an excerpt from that statement:

Applying the regulatory text of Final Rule 2021-05F, partially complete Polymer80, Lone Wolf, and similar striker-fired semiautomatic pistol frames, including, but not limited to, those sold within parts kits, have reached a stage of manufacture where they “may readily be completed, assembled, restored, or otherwise converted” to a functional frame. This definition of “readily” applies to each and every classification of a partially complete frame or receiver under this Rule, whether sold alone or as part of a kit. Therefore, even without any associated templates, jigs, molds, equipment, tools, instructions, guides, or marketing materials, these partially complete pistol frames are “frames” and also “firearms” as defined in the GCA and its implementing regulations, 18 U.S.C. § 921(a)(3)(B) and 27 CFR 478.12(a)(1), (c).

The following are some examples of companies that build 80% frames.

•  Polymer 80 

• Nomad Defense

•  Matrix Arms

•  Lone Wolf Arms
