Description

"M4 Commando" model designation engraved on the lower received with LE serial number prefix. Rare and limited availability government exclusive product.

The Colt IAR Commando is a complete, semi-automatic short barrel rifle (SBR), crafted to mirror the specifications of the select fire IAR in current use by FBI HRT. Designed for individual ownership, this limited-edition firearm delivers the compact power and precision of the original HRT contract rifle, offering unparalleled performance for tactical enthusiasts, and collectors. Chambered in 5.56x45mm NATO, the IAR6933-SBR features an 11.5" heavy barrel, a monolithic upper receiver, and a suite of mil-spec components, ensuring reliability and versatility in high-stakes scenarios like home defense or close-quarters training.
Engineered for mobility and sustained firepower, the IAR6933-SBR combines a lightweight, maneuverable design with the full ballistic potential of the 5.56mm round. Its proprietary heavy barrel and heat guard sink system provide 30-40% improved heat dissipation, making it ideal for sustained fire or suppressed use. Whether you’re navigating tight spaces or dominating the range, this SBR delivers the elite performance demanded by the FBI HRT, now accessible in a civilian-legal semi-auto configuration.

Performance and Design
Developed as a contract overrun for the FBI HRT, the Colt IAR6933-SBR is built to excel in close-quarters environments. Its 11.5" heavy barrel, thicker than a standard SOCOM profile, enhances heat dissipation and durability, maintaining accuracy during prolonged engagements. The KAC heat guard system reduces barrel heat by 30-40% compared to standard M4 platforms, ensuring performance under high-volume fire or when paired with a suppressor. The gas port is optimized for 50/50 suppressed/unsuppressed use, delivering smooth cycling.
 
 
The monolithic upper receiver eliminates rail shift, providing a rock-solid platform for optics, lasers, or night vision. Crisp, white laser-etched “T” markings ensure precise accessory placement, while the integrated gas block with folding front sight maintains compatibility with modern optics. The mil-spec forged lower receiver, paired with a Bravo B5 stock, offers durability and adjustability for any shooter. This rifle accommodates a wide range of 5.56mm ammunition, including NATO M855/SS109, U.S. M193, and longer-range Mk262 Mod1 77-grain rounds preferred by SOCOM
