Colt M4 Monolithic Carbine Semi Automatic Rifle 5.56x45mm NATO 16.1" Matte Threaded Barrel Black Frame Black Collapsible Stock

The Colt 6940 monolithic rifle is one of the most popular tactical rifles on the market, and usually one of the hardest to find. The monlithic design upper is built tough for tactical environments, and shares a common lower receiver with the rest of the M4 and 6920 family of Colt rifles. The Mil-Spec hammer and trigger pivot pins, a Magpul MBUS backup sight and a folding front sight for enhanced optical solutions, and 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. FeaturesM4 Style StockGovernment Profile BarrelTri-rail
