What Makes Faxon Firearms .338 ARC ION 12.5in Complete Upper Receiver Stand Out?
The Faxon Firearms .338 ARC ION 12.5in Complete Upper Receiver is a powerhouse designed for those seeking significant knockdown power in a compact AR platform. Faxon Firearms has chambered this upper in the potent .338 ARC, offering impressive ballistics and extended range capabilities compared to more common AR calibers. The 12.5-inch barrel strikes a balance between maneuverability and maintaining sufficient velocity for the .338 ARC cartridge. This upper aims to deliver exceptional performance in a relatively small package.
As a seasoned outdoorsman and tactical gear specialist, I often find myself needing a rifle that can handle both medium to large game and provide reliable defense against potential threats in the backcountry. I was looking for an upper receiver that offered a significant step up in power from the .223/5.56 and .300 Blackout options, while remaining AR-15 compatible. The promise of .338 ARC ballistics in a short-barreled configuration immediately piqued my interest.
Upon unboxing, the Faxon Firearms upper impressed me with its robust construction and clean lines. The black anodized finish appeared flawless, and the handguard felt solid in hand. The weight, at 4.85 lbs, felt appropriate for the size and intended use. It gives the impression of a high-quality, purpose-built tool.
Compared to similar uppers in calibers like 7.62×39 or .350 Legend, the Faxon Firearms stood out due to the .338 ARC’s superior ballistics and flatter trajectory. While other options might be more readily available or slightly less expensive, the performance advantages of the .338 ARC were the deciding factor. I chose this upper because I needed performance first and foremost.
My first impression was one of excitement. The Faxon Firearms .338 ARC ION 12.5in Complete Upper Receiver seemed to be exactly what I was looking for – a compact, powerful, and well-built upper that could handle a variety of demanding tasks. I was eager to get it mounted on a lower receiver and put it through its paces.
Real-World Testing: Putting Faxon Firearms .338 ARC ION 12.5in Complete Upper Receiver to the Test
