The Faxon Duty 5.56×45 NATO 7.5″ Mid-Length Nitride Barrel Made a Bold First Impression
The Faxon Duty 5.56×45 NATO 7.5″ Mid-Length Nitride Barrel isn’t just another AR-15 component; it’s a statement. It promises maneuverability, durability, and accuracy in a compact package, all thanks to Faxon Firearms‘ Gunner profile and meticulous manufacturing process. This barrel immediately piqued my interest, offering a potential solution for building a highly portable and effective personal defense weapon.
My existing AR pistol was nose-heavy and unwieldy, hindering quick target acquisition. I needed a shorter, lighter barrel without sacrificing ballistic performance. The Faxon barrel’s “Gunner” profile, a hybrid of Government and Pencil profiles, promised to address these issues.
The Faxon Duty 5.56×45 NATO 7.5″ Mid-Length Nitride Barrel arrived well-packaged and free from any visible defects. The nitride finish appeared even and robust, and the machining was clean and precise. The weight was noticeably less than my previous 10.5″ barrel, immediately giving me hope for improved balance.
Compared to similar 7.5″ barrels from other manufacturers like Ballistic Advantage and Aero Precision, the Faxon stood out due to its mid-length gas system. This feature is typically found on longer barrels and, theoretically, should provide a smoother recoil impulse. I also considered a Daniel Defense barrel, but the Faxon’s price point was significantly more attractive for this build.
My initial excitement was tempered with a hint of skepticism – can such a short barrel, with a mid-length gas system, deliver acceptable performance and reliability? Only rigorous testing would tell. I was both eager and cautious to see how it would perform.
Real-World Testing: Putting Faxon Duty 5.56×45 NATO 7.5″ Mid-Length Nitride Barrel to the Test
First Use Experience
My initial testing ground was a local indoor shooting range. I mounted the Faxon Duty 5.56×45 NATO 7.5″ Mid-Length Nitride Barrel onto my AR pistol lower receiver and paired it with a reliable bolt carrier group and buffer system. I wanted to assess its accuracy and reliability with various types of ammunition.
The barrel cycled flawlessly through several magazines of both 55-grain and 62-grain 5.56 NATO ammunition. There were no failures to feed, extract, or eject. The recoil impulse was noticeably milder than expected, likely due to the mid-length gas system.
Using a red dot sight at 25 yards, I consistently achieved groupings of around 2-3 inches. This was adequate for close-quarters scenarios, but I knew the barrel’s true accuracy potential could only be explored with magnified optics. A small fireball was present, as expected with a barrel this short, but it wasn’t excessive.
Extended Use & Reliability
After several range trips and hundreds of rounds fired, the Faxon Duty 5.56×45 NATO 7.5″ Mid-Length Nitride Barrel continues to impress me with its consistent performance. It has proven to be remarkably reliable, even when subjected to rapid firing and minimal cleaning.
The nitride finish has held up exceptionally well, showing no signs of wear or corrosion despite exposure to various cleaning solvents. Maintenance is simple, requiring only a standard bore brush and solvent after each range session. The chamber and bore wipe clean easily.
Compared to my previous experiences with shorter AR barrels, the Faxon is a significant upgrade in terms of both recoil management and accuracy. I have been very happy with its reliability. This barrel has definitely exceeded my expectations, especially considering its compact size.
