Overview
Overview
The Carbon 15 line is closely based on the Colt AR-15 design. Carbon 15 rifles have carbon fiber upper and lower receivers, which are lighter than the standard aluminum and steel construction of AR-15 receivers. Carbon 15 rifles are generally chambered in 5.56×45mm NATO/.223 Remington, although Bushmaster also produced 9×19mm Parabellum versions of the pistol and carbine. In early 2009, Bushmaster began to include the dust cover and forward assist in their Carbon 15 M4-style rifles.
