Simply amazing for field play. Fits a 11.1v lipo that is big for most guns. Insane RoF that the metal gearbox has no trouble supporting. Full metal handguard feels very well made. Can fit all the custumizations an M4 platform can. The MK2 has a very slick reciever and trigger, although the changes are all cosmetic.
The one gun that comes with a MOSFET that doesnt **** it up
