Like the AK47 NGRS or Next Generation Recoil Shock, this has a "recoil engine", which gives the gun recoils and the bolt moves back and forth too. It also boasts an Aluminum receiver, which is a nice addition; within the receiver, you will find a Newly-designed Mechbox. To add to that, the Magazines are of a completely new design also, so the standard Marui AK-47 Mags can not be used with this gun, you will need to get the appropriate Marui mags for this gun.
