Radical Firearms 11.5in 5.56 AR-15 Rifle Barrel Review

Let’s Talk About Radical Firearms 11.5in 5.56 AR-15 Rifle Barrel

The Radical Firearms 11.5in 5.56 AR-15 Rifle Barrel represents a compelling entry point for those looking to build a short-barreled rifle (SBR) or AR pistol. Manufactured by Radical Firearms, this barrel offers a balance of affordability and functionality, featuring a 1/7 twist rate for optimal projectile stabilization. Its carbine-length gas system is designed for reliable cycling with a wide range of ammunition, making it an attractive option for both experienced builders and newcomers alike.

I was in the market for a new barrel to complete a pistol build and wanted something that offered good value without sacrificing too much on quality. I’ve worked with various barrel lengths and twist rates over the years, and the 11.5-inch barrel with a 1/7 twist seemed ideal for the kind of shooting I planned to do – mostly close to medium-range target practice and home defense scenarios.

Upon receiving the Radical Firearms 11.5in 5.56 AR-15 Rifle Barrel, I was immediately impressed by the clean nitride finish and the overall robust feel of the steel. The threads were cleanly cut, and the gas port appeared to be properly sized. It felt like a well-made component, especially considering the price point.

I considered a few other options, like the Ballistic Advantage 11.5″ Hanson barrel and the Faxon Firearms 11.5″ Gunner barrel. While both are known for their quality and accuracy, they came with a significantly higher price tag. I chose the Radical Firearms barrel because it seemed like a solid compromise between performance and affordability, allowing me to allocate more of my budget to other essential components like the bolt carrier group and optic.

My first impression was positive; the barrel seemed well-made and ready to install. I was excited to get it mounted on my receiver and head to the range to see how it performed. I felt like this was a good product that would perform admirably.

Real-World Testing: Putting Radical Firearms 11.5in 5.56 AR-15 Rifle Barrel to the Test

First Use Experience

I tested the Radical Firearms 11.5in 5.56 AR-15 Rifle Barrel at my local outdoor shooting range, which offers a variety of distances from 25 to 200 yards. I ran a mix of .223 and 5.56 ammunition through it, including both brass and steel-cased rounds, to get a feel for its reliability and accuracy. The weather was slightly overcast, with temperatures hovering around 60 degrees Fahrenheit.

The barrel performed admirably under these conditions. I experienced no failures to feed or extract and the cycling was consistent, even with the cheaper steel-cased ammo. It took a few magazines to dial in the gas system, but once I found the sweet spot, it ran smoothly.

Installation was straightforward. I had used similar components previously and have experience with AR-15 builds, and I encountered no unexpected issues during assembly. I did need to adjust the gas block slightly to achieve optimal performance with different ammunition types, but that’s a common adjustment with any new build.

After several range trips and hundreds of rounds fired, the Radical Firearms 11.5in 5.56 AR-15 Rifle Barrel continues to perform reliably. There are no visible signs of excessive wear or damage. The nitride finish still looks good, and the bore remains clean with regular maintenance.

The barrel has held up remarkably well under sustained firing sessions. While I haven’t subjected it to any extreme torture tests, it has proven to be a durable and reliable component for general range use and training. Cleaning is simple; a standard bore snake and some solvent are all that’s needed to keep it in top condition.

Compared to other budget barrels I’ve used in the past, the Radical Firearms barrel has definitely exceeded my expectations in terms of both accuracy and reliability. While it might not be match-grade, it provides more than acceptable performance for its intended purpose. It is a great barrel for its cost.
