missing screw's

[tonicknight]

hello everyone

I need some help trying to source some missing screw's. its my friends gun and he's new to the hobby and I cant seem to find the screw's on any airsoft site. its a brand new G&G cm16 I think but after his first day he found out 2 of the hand rail screws have fallen out (as seen in picture) the shop he got it from says they cant help(they only sell gear and don't seem to do repairs or anything). I haven't been able to get to his address as he lives a fair distance away and iv had no free time. can anyone help me source 2 of the required screws?

many thanks
