Anyone know if the screws are 4-40 or 6-32? Can't get Holosun to return my email.

Think it matters more what the gun is drilled/tapped to. I had a Holosun factory screw break off in my S&W M&P 10MM that I was lucky enough to easy out and replace.
I went with screws that others suggested here.

Here’s what I ordered. The 6-32 x1/2 worked for mine.

Mine came with two sets. I put it on a Gx4 TORO, and ended up using the screws the held the cover plate on.
