The SCW features Colt’s patented one-piece monolithic upper receiver**and a Colt collapsible folding buttstock* for confined space combat operations and close quarters battle. Where previous small caliber personal defense weapons were inadequate in caliber or configuration for engaging varying target sets, the Colt SCW in 5.56x45mm NATO provides the stopping power soldiers need on the battlefield. Its ultra lightweight compact design allows maneuverability in highly confined areas of operation. The SCW also allows for quick and easy transition from vehicles and aircraft, thus providing much more firepower and range to aircrews and vehicle operators than handguns. Incorporating a new bolt carrier/buffer system, the SCW has been engineered to provide the same dependable reliability as the Colt M4 in a much more compact design.
