I am pleasntly surprised at how much I like this thing. Good plunger tube size, nice strong spring, a trigger and a breech that doesn't rip apart the ammo. The internals in general are of a much higher quality than you'd expect if you saw how little was going on inside of xploderz.
The system is driven by a rack and half gear much like a vulcan or stampede.
The breech is actually the biggest and most impressive improvement. I was use to having xploderz shatter ammo as often as it would fire correctly. This system has not broken 1 ball yet. This is amazing to me for 2 reason; the breech is working perfectly, and because this also means that I haven't hit a ball that was already broken in the pre-grown ammo.
