"Bought the gun about a month ago, and it has been fielded multiple times now. Fom the day it was delivered, i had issues. First, the gun needed an immediate rebuild, as BBs were not firing from the barrel, despite the advertised high FPS. Found out the hop-up bucking was not installed correctly, so the BB's were getting trapped in the barrel. I then looked at the gearox and found hardly any grease in it.
After the rebuild, the gun has done ok. Clear plastic hop-up assembly is less than ideal, but that can be upgraded. ROF is decent, although the FPS is lower than advertised (Chrono'd with .25g BB's yesterday at 311 FPS max). 3 stars for the metal rails, receiver, and design."
