How to zero AR iron sights

[dlewis7]

So, for the past couple days, I've been trying to find information on how to properly zero my AR's iron sights. (A3) Ive found a few bits of info on how to do it for the A1/A2, but couldn't seem to find much on the A3. Today, I ran across this PDF which explains it very well, for all versions and different barrel lengths, and I figured I'd pass it on, since it helped me out a lot.

Hope this helps somebody else too!

That's a very useful doc - thanks!

Here's an extended thread on the revised improved battle sight zero (RIBZ), with lots of info on trajectories and adjustments.

Thanks! Going to print this out and put it in the AR Binder I've been compiling.
