JG BAR 10 Screws

[bengreen]

I know this is a big ask, but if anyone has some spare time on this very rainy day, could you possibly measure/tell me the screws that are used in most of the JG BAR 10, this includes the external and most importantly the trigger mech, my clumsy friend has lost most of his (i now have his gun as a little project) and i need the screws again!

If you could tell me / link me it would be very helpful!
