Is there a good tuturial somewhere that shows how to best utilize iron sights?  My new S&W M&P has the Troy battle sights and being new to rifles, I want to make sure my thoughts on sight picture and adjustments are accurate.  Thanks in advance.

I went through this with my iron sights recently; if you look at the responses to my thread you'll find a bunch of good information: http://www.ar15.com/forums/topic.html?b=3&f=118&t=422829. The IBZ and RIBZ links are definitely worth visiting.

Thanks for the info.  I guess I'm actually questioning what the sight picture should look with the two Troy sights lined up.  More like how should the front sight look, looking through the rear...i.e. where should it be lining up.

Aperture sight are useful because we have a natural tendency to *center* things in our vision.
Think of a point...bullseye, dot, ect.  When you look at the point through the rear sight aperture, center it in the aperture *sight picture*.
Then align so that the top of the front sight post is at 6 o'clock on/under the point you see through the rear aperture and all is centered.
This is commonly referred to as 6 o'clock hold.
When the point (target) is centered in the aperture with the front sight at 6 o'clock on/under that point your sights are lined up with the proper sight picture.
Fire a group and adjust windage (side to side).
Fire a group and adjust elevation (up and down).
There are many approaches to sighting and zeroing.  This is one.  ymmv.

Remember:
The rear sight is moved in the direction you want the point of impact to move.  Up is up - right is right, etc.
The front sight is moved in the opposite direction you want the point of impact to move.  Up is down, left is right, etc.

I agree about Chuck Santos' IBZ and the RIBZ methods of zeroing too. Since you have a rear sight that doesn't adjust for elevation/range, just zero it at 50 _yards_, and that will put your "far" zero at roughly 200 _meters_ (219 yards).


***Edited to add - here's the RIBZ thread:
