Let’s Talk About Faxon Firearms .308 Winchester Big Gunner AR-10 Rifle Barrel
The AR-10 platform has always been a favorite of mine; the stopping power of the .308 Winchester in a semi-automatic package is hard to beat. However, many AR-10 rifles can be quite heavy, making them less than ideal for extended use in the field. The Faxon Firearms .308 Winchester Big Gunner AR-10 Rifle Barrel promises to address this issue by offering a lightweight yet durable barrel option for AR-10 builds.
My quest for the Faxon Firearms .308 Winchester Big Gunner AR-10 Rifle Barrel stemmed from a desire to build a lighter, more maneuverable AR-10 for hog hunting. I wanted a rifle that I could comfortably carry for hours through dense brush without sacrificing the ballistic advantage of the .308 cartridge. After doing extensive research, the Faxon barrel appeared to be the perfect balance of weight, accuracy, and durability.
Unboxing the barrel, my initial impression was positive. The nitride finish looked flawless, and the barrel felt significantly lighter than the 20-inch government profile barrel it was replacing. The machining appeared clean and precise, and I was particularly interested in the unique “Big Gunner” profile. It seemed designed for both weight reduction and heat dissipation.
I considered barrels from Ballistic Advantage and Criterion, but ultimately chose the Faxon due to its unique profile and reputation for quality at a reasonable price point. The Ballistic Advantage barrels were lighter but seemed to sacrifice some rigidity, while the Criterion barrels were known for exceptional accuracy but added unwanted weight. I was excited to see if the Faxon could deliver on its promises.
Initial impressions were positive; the barrel looked and felt like a quality piece. If it shot as well as it looked, I knew this build would be a winner.
Real-World Testing: Putting Faxon Firearms .308 Winchester Big Gunner AR-10 Rifle Barrel to the Test
First Use Experience
My first experience with the Faxon Firearms .308 Winchester Big Gunner AR-10 Rifle Barrel was at my local shooting range. I was sighting in the rifle and testing different ammunition types. The weather was mild and sunny, perfect for a day at the range.
The barrel performed admirably, exhibiting consistent accuracy with various loads. I was particularly impressed with how quickly the barrel cooled down between strings of fire; the “Big Gunner” profile seemed to dissipate heat efficiently. There were no malfunctions or issues of any kind during the initial testing.
Extended Use & Reliability
After several months of regular use, the Faxon barrel has proven to be exceptionally reliable. I’ve taken the rifle on multiple hog hunts and several training sessions, and it has performed flawlessly in all conditions. The nitride finish has held up well to the elements, showing no signs of rust or corrosion.
Durability has been excellent, with no noticeable wear or tear on the barrel itself. Cleaning is also a breeze, thanks to the smooth nitride finish; carbon fouling wipes off easily. Compared to my previous AR-10 barrel, the Faxon is significantly lighter and more maneuverable, making it a joy to carry and shoot for extended periods. It has exceeded my expectations in terms of both performance and durability.
