Colt M4 Carbine

The Colt M4 Monolithic Carbine in 5.56 NATO is a cutting-edge tactical rifle featuring a one-piece monolithic upper receiver for improved rigidity and accuracy. Designed for durability and modularity, it includes a full-length Mil-Spec rail from the receiver to the front sight for superior optics mounting. The patented one-piece monolithic upper receiver incorporates a continuous Mil-Spec rail from the rear of the upper receiver to the front sight. This feature affords unmatched repeatability for mounting optical systems, not found with separate handguard rail systems. Designed with accuracy in mind, its true free-floating barrel provides the enhanced accuracy necessary for long-range acquisition capability.
