right out of the box the build of the gun seemed to be of great quality. The accuracy of the gun proved to be out of this world as was making 45-50 yard shots with the grouping of a door. The rate of fire was quite impressive at about 800 rpm with a 9.6v battery. However, there is an incredible problem about the gun with its magazines. The mags for gun do not fit in the gun well at all. there is a lot of movement in the mag when inside the gun an can even be taken out by moving the mag back and fourth. This problem occurred with all the mags for the gun. This also led to the huge problem of the mag not feeding unless it was held up into the gun. So overall ok gun but bad feeding system.
great metal body
easy to work on
compatible with a few mp5 accesories
will not feed the rounds into the chamber without holding the mag
