I went to my local airsoft shop today to look for a replacement for my current gun. I was specifically looking for this one. When I asked the guy working the counter if the shop could order G&P airsoft guns (as they don't stock them), he said they could but don't because "they're crap."
In my airsoft experience, I've never heard bad things about G&P; lots of praise goes out for their externals, some of which are lauded as the best on the market. The store attendants told me that while that was true, the G&P internals were sub-par, and recommended CA, E1, and Modify GB's as better quality alternatives (the Modify option probably is). They also included some pretty horrific stories about failures of the metal bodies themselves.
I was hoping this would be my entry into the high-end replicas, but I have absolutely no experience with G&P (or any other high end manufacturer for that matter). While I know that no airsoft gun lasts forever, I trust these guys' opinion for the most part. I'd really like to hear everyone's experience with this brand, and whether parts failure is a constant issue, or even one final spectacular explosion. Also, if G&P really is crap, is there a similarly-priced and modded alternative to the above replica?
