Gents, I managed to lose two of these screws they hold the bottom and the top of the handguard together. If I measured them right they are 6mm long and 4 wide.
Does anyone know what kind of screws are these? I don't want to buy a 1000pc screw set from amazon if I dont have to.:)
 
I can't say what the fastener size is as I don't have the Sigmaco hand guard, but for machine screws these guys are probably one of your best bets in Canada:

They also strip really easy, I got a few replacements for free from sigmaco. Maybe you can contact him through his lawyer?

Seriously though, you could try your luck at boltsplus or any specific machining hardware stores
 
They are M4x0.7 and are 6mm long. As a note, 0.7 is the standard pitch for M4, so they may just be listed as M4 x 6mm.

If you go on Amazon and search “uxcell m4 x 6mm Phillips”. That’s what you’re after. More strip resistant.
