Zeroing Iron Sights using the RIBZ Method

RIBZ = Revised Improved Battlesight Zero

For zeroing my rifle with the iron sights, I use the RIBZ method found on the AR15.com website.  This method allows for setting the rear sight for 50 and 100 yard ranges, as well as the typical 300-800 meter ranges.  (Remember to adjust the front sight post for zeroing the elevation, and the rear sight dial for adjusting for range only.)

When using the detachable carry handle as I am, you must double the number of clicks in this procedure (the elevation ring is adjustable from 300-600 meters).

Here is the procedure on the AR15.com website:

For my setup (detachable carry handle with 3/6 elevation wheel) the following settings apply:
3/6 -4 clicks for 50 yards
3/6 -6 clicks for 100 yards
3/6 for 300 meters
4 for 400 meters
5 for 500 meters
3/6 for 600 meters

When it comes to what settings to use for self defense...I always leave the sight set to the 50 yard setting, this will keep me within -3 to +1.5 inches from muzzle to 280 yards.  This way, there will be no thinking about sight settings in a stressful situation.
