As the post above me said G&G's have better internals, there barrel is a 6.035 bore, there wiring is not shoddy, and the hop up is excellent. As for the externals, no they do not have the real steel trades but the trades are still very nice, there are no creaks in the stock, the plastic has no seam lines, and the metal is higher quality that classic army's. G&G's are also cheaper the CA's, in the experiences I've had G&G's are better.
