No it's not the H&K MP5K, have a closer look! It has an M4 receiver and takes M4 magazines...
Let me introduce to you the new M4 Tactical Pistol Series from Ares Airsoft wich should be good primaries for CQB games or as backup AEGs for airsoft snipers. The series come with the EFCS or Electronic Firing Control System which is a MOSFET but can be easily be reprogrammed using the EFCS box from Ares Airsoft.
Three models will be available in the series: M4-CCP which does not come with a folding stock; the M4-CCC that does come with folding stock but has a snub front end; and the M4-CCR which has a flash hider protuding from the front handguard. All of these models will have black and dark earth versions and are LiPo ready.
Availability is not yet know, however expect an extended review soon on NLAIRSOFT.COM!
