ya Ive been looking all over for info, apparently is a ver 2 mech box with 8mm bearings also small amount of air is cycled from the main chamber and used to drive the Fake bolt back and spring pressure returns it to the closed position. by use of a second small piston on top of the mech box. so basically its an AEG with pneumatic blow back. you can fire the weapon and hold the bolt and has no adverse effects because the only connection between the fake blow back and the firing of the bbs is air ! I'm just curious as to installing and upgrades to it like a dovetail RIS and maybe a battery crane stock and if anyone has purchased one and what there thoughts are on quality and how happy they are with it or not?
