It's an airsoft replica.
The term "CAR-15" covers all of the early short barreled variants of the M16; the airsoft "CAR-15" is in fact a Colt Model 607 which never went into major production. A limited number were purchased by the US Army under the designation GX-5857. Non military versions are marked Mod. 07 / Mod. 07A / Mod. 07B.
Within a year it was superseded by the Colt Model 609 and 629, the XM177 series "Commando" rifles, which did see military service. The model 619 was the Export version of the 609 and they were built in the US.
