The Faxon Firearms Gunner Duty Series 5.56 NATO 12.5″ Black Nitride 4150 CMV Made a Bold First Impression
The Faxon Firearms Gunner Duty Series 5.56 NATO 12.5″ Black Nitride 4150 CMV barrel promises to be a performance upgrade for any AR-15 build. Faxon Firearms is a well-respected name in the industry, known for quality and innovation. This particular barrel piqued my interest because I was looking to build a more compact and maneuverable AR-15 for close-quarters training and home defense.
Years of using longer barrels had me seeking something different. Maneuvering inside structures with a rifle can be cumbersome. I needed a shorter, lighter barrel without sacrificing too much ballistic performance.
Upon receiving the Faxon Firearms Gunner Duty Series 5.56 NATO 12.5″ Black Nitride 4150 CMV, I was immediately impressed. The black nitride finish looked flawless and felt incredibly smooth to the touch. The barrel’s weight, or lack thereof, was noticeable right away. Compared to a few other barrels I’ve used, such as a 16-inch standard profile and a 14.5-inch government profile, the Faxon Firearms barrel was substantially lighter. I chose this barrel because of its balance of length, weight, and potential accuracy. My initial excitement was high; I felt I had found the perfect barrel for my needs.

First Use Experience
My initial testing of the Faxon Firearms Gunner Duty Series 5.56 NATO 12.5″ Black Nitride 4150 CMV took place at an outdoor shooting range.
