Unity Tactical FAST QD Lever

I ran my FAST mount for about a year with the standard screws. Wanted QD so I can easily swap back to an LPVO for a class. Was surprised that there was little shift (3-4 clicks) going from from fixed to QD and checking my zero. Once zeroed with the QD, I removed and replaced the sight 4 times and didn’t see a shift at 50yds. Was a very windy day, so I didn’t try the same at 200yds.

This is made by ADM (American Defence Manufactuing) which makes great products, but why is it listed as "Unity"
