[The Saint]

1. I can't say much about the chemistry beyond that my G&G's metal body has shown no sign of wear, but the steel parts that came with my KA stock are rusting. Both parts have received equal amounts of weathering, since I put the KA stock on before ever fielding the gun.

2. My G&G GR16A3 came with bearing piston head and bearing spring guide. The spring guide was not fully metal. It shot ~360fps stock, it's now shooting 400fps on the dot after replacing the spring, piston assembly, nozzle and spring guide. I was not originally planning on replacing the piston assembly nozzle and spring guide, but I had the parts on hand. My opinion of the stock G&G internals is that they looked pretty good, though the bearing spring guide's bearings had seized on arrival.

Stock shimming wasn't bad at all. The mechbox itself is very well made, IMO. Good tolerances. I don't remember if it's reinforced or not, but I use a Sorbo cylinder cushion anyways.

3. Stock bucking is pretty poor, but that can be said for almost all brands. The hopup unit itself is plastic, not metal, but I've noticed absolutely no problem with it.

4. Unless they are quoting G&G, they're full of shit. G&G had crappy early QC the same way CA had crappy early QC, the same way any company have crappy QC: insufficient attention to detail. Advertising doesn't enter into the calculation.
