This specific firearm component is a 14.5-inch barrel manufactured by Daniel Defense, designed to meet government profile specifications. These specifications typically involve a heavier profile under the handguard for increased rigidity and heat dissipation, and a standard profile forward of the gas block to maintain a manageable weight. This combination aims to balance accuracy, durability, and handling. The 14.5-inch length makes it suitable for a variety of applications, while requiring a permanently attached muzzle device to reach the legal 16-inch minimum barrel length for non-NFA rifles.
The choice of this component often reflects a desire for a high-quality, reliable barrel built to exacting standards. Daniel Defense has a reputation for producing durable and accurate barrels, making this a popular choice among military, law enforcement, and civilian shooters. Historically, the 14.5-inch length coupled with a carbine-length gas system has been a favored configuration for its balance of maneuverability and ballistic performance. The “government profile” further enhances these characteristics by offering improved heat management and stiffness, crucial for sustained firing and consistent accuracy.
