G&P Metal M4 RAS AEG with Masterkey Shot Gun (Style A, Black)

M4 RAS is the M4A1 Carbine which equips with the RAS (Rail Accessory System) handguard ,  as the standard equipment for the M4 / CQBR used by US Special Force based on the SOPMOD block I (Special Operations Peculiar Modification) developed by USSOCOM.

The Masterkey is an under-barrel door breaching shotgun system developed in 1980s. This project wants to provide assault rifle with a built-in breaching tool and let soldiers no need to carry an extra breaching shotgun on the battlefield. It consists of a Remington M870 shotgun mounted on a M16 or M4 assault rifle in an under-barrel configuration, like the M203 grenade launcher. Independent stock is needed when need to use the Masterkey as a stand alone weapon which can also used with the M203 grenade launcher as Masterkey cannot used independently.

The Masterkey is only a tested type modular weapon in US army, but it successfully inspired the M26 (called XM26 when testing) under-barrel shotgun attachment and chosen by US army as the new breaching tool.
