Review:
Well, its a timmy folks. 2k2. Simple in design, easy to mantain. Stock wise, its fine, but everybody wants something different for it. From there, get a clam shell, or the new alias frames. The clam shell is so comfy, and dirt cheap now. The design and milling of the GZ is pretty cool, I have the dark blue body and a silver ram sleeve, and man does it loook fine. Take this baby out, and it shoots just like another timmy would, keeping that its a 2k2 in mine.
Conclusion:
Great marker, well built, and simple in design and easy to clean up and go.
