Video: Zeroing an AR Platform Rifle
Russ Chastain 03.20.20
In the video below, Paul Harrell goes through the motions of sighting in an AR type rifle — but not before he addresses some viewer complaints, in which some people were whining about a previous video in which Paul compared an AR to a Mini 14.
If you’re not interested in a urinating match between Paul and his commenters (I wasn’t) skip the first five minutes of the video. For real.
He starts with the A1 version, giving a summary of how the sights are set up, how to reset them to “mechanical zero,” and how to make sure you turn the front sight in the proper direction. Then he explains ballistics a bit and actually zeros the rifle by shooting first at 25 and then at 300 yards.
From there, he shoots at 100 yards to demonstrate the difference in point of impact with the long range and short range rear sight apertures.
After that, he moves on to the A2, which he happily notes is exactly the same, “except for the fact that it’s completely different.”
He starts out by providing textbook info, which is what worked pretty well for the A1. Then he acknowledges that the textbook falls short with the A2, so he demonstrates the way he does it with his A2 rifle. I’ll spare you a summary here; just watch the video to see how he does it.
