The Carbon 15 is a family of lightweight, magazine-fed pistols, carbines, and rifles developed by defunct United States weapons manufacturer Professional Ordnance, with the design later picked up by Bushmaster Firearms.

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.
