Let’s Talk About Faxon Firearms 10.5 inch Gunner Big Bore Profile .458 Socom Barrel
The Faxon Firearms 10.5 inch Gunner Big Bore Profile .458 Socom Barrel promises to deliver big bore power in a compact AR-15 package. Manufactured by Faxon Firearms, this barrel aims to provide accuracy and reliability, catering to those seeking a potent and maneuverable platform.
I embarked on this endeavor hoping to build a formidable hog hunting AR pistol. My quest demanded a barrel capable of delivering devastating knockdown power at close to medium ranges, all while maintaining a reasonable footprint for maneuverability in dense brush.
The Faxon Firearms barrel arrived well-packaged and immediately impressed with its clean nitride finish and substantial feel. The weight felt appropriate for a big bore, instilling confidence in its ability to handle the .458 SOCOM’s hefty recoil. Comparing it to a standard 5.56 barrel, the difference in heft was immediately noticeable, promising a different level of performance. I was excited to start the build.
Considering alternatives, I initially eyed barrels from Tromix and SBR Ammunition, renowned for their .458 SOCOM expertise. Ultimately, I chose the Faxon Firearms option due to its attractive price point and the “Gunner” profile, which seemed to offer a good balance between weight and rigidity. My excitement was high, envisioning the possibilities this barrel unlocked for my hog hunting adventures.
Real-World Testing: Putting Faxon Firearms 10.5 inch Gunner Big Bore Profile .458 Socom Barrel to the Test
First Use Experience
My initial test took place at an indoor shooting range, a controlled environment to evaluate the barrel’s basic functionality. The range offered a 50-yard lane, perfect for establishing a baseline for accuracy. I used a variety of .458 SOCOM ammunition, including SBR Ammunition’s 300-grain Barnes TAC-TX and 350-grain FMJ rounds.
The first few rounds resulted in failures to feed, with the bolt carrier group jamming against the base of the cartridge. Examining the rounds, I noticed distinct gouges on the case, indicating an issue with the chamber’s feed ramps. Despite this setback, I persisted, hoping the issue would resolve itself with continued use. Unfortunately, the feeding problem persisted.
Extended Use & Reliability
After the initial range session, I dedicated considerable time to diagnosing and resolving the feeding issue. Frustrated by Faxon’s lack of response to my support inquiries, I resorted to meticulously polishing the feed ramps with a Dremel tool, a task I reluctantly undertook. After careful polishing and multiple test fittings, the feeding issues seemed to subside during hand cycling.
Subsequent range trips revealed acceptable accuracy, with groupings around 2-3 inches at 50 yards, which I found acceptable for a short-barreled .458 SOCOM. However, the initial reliability issues and the necessity for significant modification left a lingering sense of disappointment. Despite the modifications, I still harbored concerns about the barrel’s long-term durability and reliability. This experience highlighted the importance of thorough quality control.

Performance & Functionality
The Faxon Firearms 10.5 inch Gunner Big Bore Profile .458 Socom Barrel, after modification, delivered adequate accuracy. The large .458 SOCOM round offers significant stopping power for close to medium range engagements. However, the initial reliability issues were a major concern.
The barrel’s biggest strength, once the feed ramp was addressed, was its ability to chamber and fire the powerful .458 SOCOM round in a short platform. The main weakness was the need for significant gunsmithing to achieve reliable feeding. Faxon needs to improve its quality control processes.
Design & Ergonomics
The build quality is generally good, with a clean nitride finish and a substantial feel. The “Gunner” profile strikes a reasonable balance between weight and rigidity, making it manageable on an AR pistol platform. However, the improperly machined feed ramps detract from the overall impression.
The barrel itself isn’t particularly user-unfriendly, but the necessity for modification introduces a significant learning curve. The required modifications are beyond the capabilities of most casual shooters. This makes it a problematic choice for novices.
Durability & Maintenance
The 4150 CMV steel construction and nitride finish suggest good long-term durability. However, the feed ramp modification potentially compromises the barrel’s lifespan, as material was removed. Regular cleaning and proper lubrication are crucial for maintaining the barrel’s performance.
Maintaining the barrel is straightforward, requiring standard AR-15 cleaning procedures. However, the need to monitor the modified feed ramps for any signs of wear or damage adds an extra layer of complexity. Proper care is essential.
