Colt M4 CR 6940 Monolithic Carbine

Getting Mono in High School was bad. But getting a Mono Upper Colt Carbine is good. The Monolithic upper is a solid continuous rial for mounting all the goodies.

The advantage of the LE6940 is unmatched. The LE6940 displays fresh ingenuity with Mil-Spec hammer and trigger pivot pins, a Mil-Spec backup iron sight and a folding front sight for enhanced optical solutions, a straight gas tube and a removable lower rail which provides modularity for under mounting accessories. 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.
