This specific component configuration refers to a rifle barrel manufactured by Daniel Defense, measuring 14.5 inches in length and including a pre-installed gas block. The gas block is a critical component of the gas operating system, harnessing expanding propellant gases to cycle the action and facilitate automatic or semi-automatic fire. A 14.5-inch barrel offers a balance between maneuverability and velocity, making it a popular choice for various applications.
The combination of a reputable manufacturer like Daniel Defense with this particular barrel length and integrated gas block is often sought after for its potential accuracy, reliability, and out-of-the-box functionality. The pre-installed gas block simplifies assembly and can contribute to consistent performance by ensuring proper alignment. This configuration is frequently selected for building short-barreled rifles (SBRs) or AR pistols, and with the appropriate paperwork and tax stamp it can become the foundation of a highly effective firearm, with the gas block being critical for reliable function. Historically, 14.5-inch barrels have seen extensive use in military and law enforcement contexts.
