for standard a2 sights, how from up the barrel are the front sights?  I'm making a dissy and the gas block position is usless.

Are you asking the dimensions to locate the FSB of an A2 20" barrel or 16"?

20".  classic m-16 a2 type :)

Edit. I worded my question poorly, I'll try again.

I have a mid length gas system, but rifle length free float tube, so where do I put the front sight so it will be where a rifle with a rifle length gas system/20" barrel would have it's front sight?
