Okay....so I put the sight on the lathe today. I took about 3mm off of the detent which still left a nice cup for the spring to seat in. I cut about them off of the threads, which, honestly was about 1mm overkill. I just dressed the lead in with a file at 45 degrees. I ALSO replced the factory detent spring with another spring with a wire diameter about 3/4 of the original and maybe one coil shorter. It has plenty of hold on the detent.
I used a 23/64 collect in a Victor lathe to hold the sight post by the skirt. It took several tries to get the runout concentric. While I was at it, I took Matthew_Qs advice and I took about 1mm off of the sight post AND I moved the tangent radius that blends the sight to the shirt down about 1.5mm. I then parked and painted the assembly and put it back together. MUCH better than factory.
NOW I can adjust the damn thing right! Gonna test it next week while that cheap assed Vortex is off getting fixed. ( I killed my Vortex Spitfire AR in less that 250 rounds, LOLOLLL....as I predicted )
The un-modded sight is on the green back ground, and the modded sight is on the yellowish background:
You can see how deep I can get the sight to go. By the way, the Magpul MBUS sight tool as MUCH better for adjusting the sight once modded. The CZ tool is barely adequate.
