The salt bath Nitride Melonite/QPQ finish gave it a smooth, durable feel, suggesting good resistance to wear and corrosion.
Compared to similar .45 ACP barrels from other manufacturers, like those from Quarter Circle 10 or CMMG, the FM Products barrel stood out for its dedicated focus on weight reduction. While others prioritize different features, like increased rigidity or fluting patterns for cooling, the FM Products Ultra Light .45 Barrel, 16 inch clearly prioritizes a lightweight profile for enhanced handling. I chose this barrel specifically for that purpose.

First Use Experience
My first range trip with the FM Products Ultra Light .45 Barrel, 16 inch installed in my AR-15 pistol build was at an outdoor range in moderate weather conditions. I tested it with a variety of .45 ACP ammunition, ranging from standard 230-grain FMJ to lighter 185-grain JHP rounds.
