This specific barrel configuration typically refers to a 14.5-inch long barrel manufactured by Daniel Defense, featuring a “government profile.” A government profile barrel is characterized by a thicker profile under the handguard and a thinner profile towards the muzzle. This design balances weight and rigidity, offering improved accuracy potential during sustained fire while remaining relatively lightweight for maneuverability. Such barrels are frequently selected for modern sporting rifles and are often paired with a permanently attached muzzle device to reach the legal 16-inch minimum barrel length.
The combination of the manufacturer’s reputation for quality, the specific length, and the government profile makes this barrel a popular choice among enthusiasts and professionals. The 14.5-inch length, when paired with a permanently attached muzzle device, offers a compact and balanced weapon system suitable for a variety of applications. The heavier profile under the handguard aids in heat dissipation and reduces barrel flex, contributing to improved accuracy. Historically, similar barrel profiles have seen extensive use in military applications, demonstrating their effectiveness and reliability.
