Halt the presses, I did what I should've done in the first place and just asked SLR Rifleworks. They emailed me back in about 5 minutes and said they actually started including the screws as of today. They are sending me a set free tomorrow, awesome customer service from them.
Thanks for the help though, little details like that often trip me up.
It's a good thing you got hooked up because the only M3's I've got now are 12 & 25 long. I did try, spent the last OT hour of the week browsing 500 bins of stock.
