Bushmaster 5.56 NATO Threaded Barrel Review

First Impressions of Bushmaster 5.56 NATO Threaded Barrel

The Bushmaster 5.56 NATO Threaded Barrel promises a blend of durability and performance for AR-platform enthusiasts. Bushmaster, a name synonymous with reliable AR components, offers this 11.5” barrel as a potential upgrade or a key piece in a custom build. Boasting a 4150 CMV steel construction and a salt bath nitride finish, it aims to provide both accuracy and longevity.

I was in the market for a shorter barrel for a pistol build, prioritizing maneuverability without sacrificing too much ballistic performance. I needed a barrel that could hold its own at the range, but also be compact enough for comfortable carry in a backpack during hikes. I have built several AR pistols in the past, including one chambered in .300 Blackout.

Upon unboxing, the Bushmaster 5.56 NATO Threaded Barrel felt solid and well-made. The nitride finish gave it a smooth, almost slick feel, and the H-BAR contour seemed substantial without being overly heavy. The threads were clean and precise.

I considered barrels from Ballistic Advantage and Faxon Firearms, both reputable manufacturers known for accuracy. Ultimately, the Bushmaster barrel’s price point and the brand’s solid reputation swayed my decision. I was also interested in trying out the H-BAR profile in a shorter barrel to see how it affects balance and recoil.

My first impression was positive. It felt like a quality component ready to be integrated into a build. I was eager to see how it would perform on the range.

Real-World Testing: Putting Bushmaster 5.56 NATO Threaded Barrel to the Test

First Use Experience

My initial testing took place at an outdoor range in mixed conditions – sunny with a slight breeze. I mounted the Bushmaster 5.56 NATO Threaded Barrel on a pistol lower receiver with a quality brace and a red dot sight. I fired a variety of 5.56 NATO ammunition, ranging from 55-grain FMJ to 62-grain green tips.

The barrel performed admirably, producing consistent groupings at 50 yards. Recoil was manageable, and the flash signature, while noticeable, wasn’t excessive. I experienced no malfunctions and the barrel remained relatively cool even after extended strings of fire.

Extended Use & Reliability

After several range trips spanning a few months, the Bushmaster 5.56 NATO Threaded Barrel has held up well. There are no visible signs of wear or corrosion, even after being exposed to varying weather conditions. Cleaning is simple, with carbon fouling easily removed from the nitride finish.

Compared to a previous 10.5″ barrel I used, the Bushmaster barrel exhibited slightly better accuracy and felt more robust. The H-BAR profile might contribute to improved heat dissipation. I am pleasantly surprised at how well it has performed over time.
