I have some pictures on a 2nd upper I did this mod too I will post later. Also I used 2 length's of hex screws 17 and a 20mm. The tap I used was a 4Mx0.7 from the kit.

Here some pics

I did my 2nd tap about 2-3mm towards the delta ring threads so that the hex screw push's exactly center on the Ra-tech hopup nub then HKp30 when he tapped it in the center of the rail. 3rd pic looks off but its the angle of how I took the picture. Both ways work fine. Hope this helps everyone.
