Is it possible for me to zero an AR or M1 with iron sights and a laser boresighter>?
How do I do it?

I've not used one, but I gather the bore-sighter gizzie goes in the chamber? Aligns with the bore?

So: Ya gotta have a table or benchrest or something where you can pad (sandbag) the rifle into position. Put the laser onto a surface out at 50-ish yards or so. And, have the red dot be visible. Shaded surface, maybe...

Then, just adjust the sights to it, with whatever is your own preferred sight-picture. After that, it's time to shoot, being reasonably sure you'll be on the paper. :)
