The post entitled Mystery AR-15 SBR Adopted By New Libyan Armed Forces I incorrectly identified the magazine used as the Magpul PMAG. The was incorrect. The magazine is a Oberland Arms OA-MAG. The OA-MAG was clearly designed to imitate the external design of the Magpul PMAG.
I apologize to Magpul for stating that their magazine had been adopted by Libyan forces.
( In the above photo the OA-MAG is left, the Magpul PMAG is on the right. )
