Aero Precision does not state the set screw spacing on the Aero Precision Adjustable Low Profile Gas Block. I recommend contacting Aero Precision in regards to that information.

the .485 spacing is correct. I just got finished getting off a chat with the arrow Precision folks but they said they don't recommend dimpling as it would void their warranty. now I don't know if they were talking about the barrels or the gas block. the only thing they said was to properly torque the set screws to 40 ft/lbs and not to use any kind of thread locker. I was replacing a standard gas block with an arrow Precision gas block I had laying around, the one I was replacing it with was a ballistic Advantage which of course is the same company that had Red Thread Locker on it. go figure

.500 for the .750. I don't know if the other diameters are the same
