I can't find this info ANYWHERE!

How many MOAs are covered by the standard (0.070") A2 front sight on a 20" barrel?

How does one go about adjusting the Trijicon CP25F front sight post? This sight has a thicker base than the standard sight, so the 4-prong front sight adjustment tool just can't quite push the retaining pin far enough out of the way to allow the base of the sight to rotate. Does anyone make a front sight adjustment tool with a deeper reach?

I believe 1'2".
Use a finish nail to push in the detent and turn post with a pair of needle nose on the Trij.

I measured my Bushmaster upper and from the rear sight to the front post it measured exactly 20". If your eye ball was a bit farther back the angle would change a bit.

So doing a bit of trig

B=20.1" (yeah I know)

Angle equals 0.20053440944962447 or 3.565056167993324 MILS or 12.032064566977468 MOA

Allowing 1.5 inches of eye relief or A=21.5" I get the angle of 0.18654373927515996 or 3.3163331426695106 MILS or 11.192624356509597 MOA

So figure that the front post covers one foot at 100 yards give or take a inch depending on where your eye is sitting.
