Faxon Firearms 5.56 NATO Gunner Rifle Barrel Review

Let’s Dive into Faxon Firearms 5.56 NATO Gunner Rifle Barrel

The Faxon Firearms 5.56 NATO Gunner Rifle Barrel promises to deliver a balance of performance, weight, and value. Faxon Firearms has a solid reputation, and this barrel aims to be a sweet spot between a lightweight profile and a heavy bull barrel. This particular barrel has been on my radar for a while as I looked to optimize the weight and accuracy of my go-to AR-15 build.

I needed a barrel that could handle consistent use at the range and potentially serve in a defensive role. My previous barrel was overly heavy, making the rifle front-heavy and cumbersome during extended shooting sessions. I considered options from Ballistic Advantage and Criterion, but ultimately the Faxon Gunner profile and nitride finish caught my eye.

The Faxon Firearms 5.56 NATO Gunner Rifle Barrel arrived well-packaged and immediately impressed with its sleek black nitride finish. The weight felt noticeably lighter than my previous barrel, and the machining appeared clean and precise. The 11-degree target crown looked expertly done.

Compared to the Ballistic Advantage Hanson profile, the Faxon Gunner felt like a better compromise between weight and rigidity. While the Criterion CORE series are known for superb accuracy, the price point of the Faxon was a major deciding factor for this build. I was excited to get it installed and hit the range.

My first impression was one of cautious optimism; the barrel looked great, and I was eager to see if it could live up to the hype in terms of accuracy and overall performance. Initial excitement was tempered with the hope it could improve the rifle’s balance and accuracy.

Real-World Testing: Putting Faxon Firearms 5.56 NATO Gunner Rifle Barrel to the Test

First Use Experience

I initially tested the Faxon Firearms 5.56 NATO Gunner Rifle Barrel at my local outdoor shooting range. The weather was mild, around 70 degrees, with a slight breeze; perfect conditions for sighting in a new barrel. I ran a variety of ammunition through it, including 55gr FMJ, 62gr Green Tip, and some 77gr OTM rounds for accuracy testing.

The barrel performed admirably right out of the gate, exhibiting consistent groupings at 50 and 100 yards. I experienced no malfunctions or cycling issues, even with the different bullet weights. The rifle felt significantly more balanced compared to its previous configuration; the lighter barrel made transitions between targets much faster.

It took very little time to adjust to the new barrel, and the improvement in handling was immediately noticeable. I was initially concerned that the lighter profile might lead to increased barrel whip and reduced accuracy, but this wasn’t the case. No real issues after the initial range trip, apart from needing to fine-tune my optic to the new point of impact.

Extended Use & Reliability

After several months of consistent use, the Faxon Firearms 5.56 NATO Gunner Rifle Barrel has held up exceptionally well. I’ve put approximately 3,000 rounds through it, and it still maintains excellent accuracy and shows no signs of degradation. Cleanings have been simple, and the nitride finish still looks brand new.

There are no visible signs of wear and tear beyond normal carbon buildup, which is easily removed with a standard cleaning regimen. The nitride finish has proven to be extremely durable and resistant to scratches and corrosion. I clean it after every range trip, which consists of running a bore snake through it, followed by a thorough cleaning with CLP.

Compared to my previous experiences with chrome-lined barrels, the Faxon barrel has delivered better accuracy and a more balanced weight. My previous barrel, while reliable, was simply too heavy for my needs. This Faxon barrel consistently shoots sub-MOA groups with match-grade ammunition, something I couldn’t achieve before.
