The Colt SOCOM 14.5" barrel stands as a cornerstone in the world of tactical weaponry, integral to the M4A1 rifle in Block 1 and Block 2 configurations. Known for its exceptional balance of ruggedness and precision, this barrel is a testament to Colt's commitment to quality and performance in military-grade equipment.
In tactical operations, operators frequently encounter the limitations of conventional rifle barrels, such as susceptibility to rapid wear and decreased accuracy under high-intensity usage. These challenges often lead to a compromise in performance, with barrels failing to endure the relentless demands of combat and environmental extremes.
The Colt SOCOM 14.5" barrel, initially designed for the M4A1 rifle, represents a significant advancement in barrel technology. Its development was driven by the need for a barrel that could handle full-auto fire efficiently, leading to a design that is 28% thicker than the government profile​​. This increased thickness not only enhances heat dissipation but also maintains structural integrity during prolonged usage.
A notable feature of the SOCOM barrel is its ability to achieve sub-MOA accuracy, a remarkable feat for a mil-spec, chrome-lined barrel​​. Additionally, this barrel accommodates the Allen Engineering M4 collar, enabling the attachment of an AEM5 suppressor for added versatility in tactical scenarios.
Unique Fact and Customer Insight: "One of the lesser-known yet intriguing aspects of the Colt SOCOM barrel is its wall thickness under the handguards, measuring .626. This precise dimensioning contributes significantly to the barrel's heat management capabilities, a critical factor in sustaining accuracy during rapid fire scenarios" (source: The New Rifleman).

Note: This barrel will come with factory front sight post and mil spec barrel nut. IF YOU ARE USING A DIFFERENT RAIL, let us know, and send us the barrel nut. We will install the barrel nut for your rail. If you wish, we can assemble your entire upper receiver group for you for a small fee. Keep in-mind that a barrel nut cannot be removed once the muzzle device is attached. We have a certain number of muzzle devices that we have committed to the manufacturers to use with this barrel, but each barrel is pinned and welded as ordered, except for the Colt factory extended A2, which comes fully assembled from Colt.
Note: The unpinned barrel is subject to all NFA laws and local regulatory oversight for a short-barreled rifle. Be sure you are familiar with all laws and that you can own and possess a short rifle barrel, or short barreled rifle.
