Hi everone, just thought i would share an online shop i stumbled across by chance, they are called "fg airsoft" they are based in france and do some funky upgrades for a select group of gbb in both pistols and rifles, i have just bought a barrel nut and spanner for a we g39 both invaluable, a very good price and very quick delivery, so if you have a gbb look them up, oh almost forgot they are also on youtube with show and tell vids on how to fit your goodies , i know its a blatent ad but they will get my custom back thanks for looking.
