G&G tend to be hit or miss. Every single one that has come across my workbench has been totally fubar. Everything from mostly garbage internals to trigger contacts made from such a soft metal they weld themselves together after a while and the gun is stuck on full auto unless you disconnect the battery. Others have had some really good luck with G&G guns.
Personally for an armalite I would stick with CA, G&P, or ICS, CA being the cheapest on the list. You can find several for sale in the sales area.
