Shoots like any other damm CA M15. ROF is pretty high, but Im starting to notice that with the CA guns, with the new motors they have. (or what ever is is there doing)
The gearbox internally has all the same upgraded parts as any of the newer CA M15s. The nozzle is longer though, and I didnt pay attention to the cylinder head, to see if it was longer also, like on AUGs.
Externally the gearbox is the same, except its missing the ring in the front where the mag catch would go through. Because it has its own ambi-catch, which is kinda part of the lower. I didnt want to mess with it, too many small parts. And the selector plate is huge.
Getting gearbox out is a pain. Good luck with getting the gearbox out for a first timer. Someone will be breaking something trying. Really recommend doing what needs to be done once. I had put in a PvPrts 110 spring, since everything else was pre-upgraded, a no need to be changed. Shooting 390s w/ .20s. Withthe Mini 8.4v it seems to have the same ROF(im sure its a little lower)
Im tired i'll continue this later, any questions???
