Colt's M4 Monolithic Carbine features a one-piece upper receiver for superior rigidity and accuracy. The 16.1-inch chrome-lined barrel, Magpul MBUS sights, and full Mil-Spec rail system provide professional-grade performance in a maneuverable 30-round platform.
The Colt CR6940 represents a thoughtful evolution in modern rifle design. Its defining feature—the patented one-piece monolithic upper receiver—eliminates the separate handguard rail system found on conventional designs. This integrated approach delivers superior repeatability for mounting optical systems and accessories.
Barrel and Accuracy: The 16.1-inch government-profile barrel features a 1:7 twist rate and is chrome-lined for durability. The free-floating design enhances accuracy for both close-quarters and extended-range work.
Sights and Optics: Magpul MBUS rear sight and folding front sight provide quick target acquisition. The continuous Mil-Spec rail running from the rear of the upper receiver to the front sight offers unmatched flexibility for mounting optics and accessories.
This rifle suits both professional applications and civilian sport shooting, delivering reliability and accuracy in a proven platform.
