Just got a new upper and tried to remove the rail screw hole filler screws. One came right out but two were stuck. I made sure the Screwdriver fit the slot. The ends of the slot basically just twisted away like they were made of clay. Improper hardening or just soft steel screws? In any case I need options. I have them soaking in PB blaster now. How do you drill out screws this small?
