Why does it only come with 3 screws

It comes with 3 screws because the vast majority of milspec lower receivers on the market only have 3 holes.

Are the set screws flat or tapered? In the picture they appear to be tapered.

Screws are round. Not like the picture. Wish they woulda included an Allen wrench with it, especially being so small. I bought 2 n one didnt fit very well with screw n hole but I was able to force it together. Color is a little off.
