I don't think it does anything to promote gun rights education. I think it probably antagonizes people and may push fence sitters off the fence the wrong way.
Look at it like this, if an anti gun activist was walking up and down your block with a megaphone ranting about stuff it would probably irritate you and it certainly wouldn't sway your opinion. If these young men want to educate people about gun rights then they should put on a jacket and tie, print up some literature and hit the streets to make their case.
That they stated in the article they thought people would approach them for conversation while carrying ARs is an indicator that they didn't think this through very well.
The best I can say is good thought, sharing information about gun rights, but really nonsensical execution. There are lots of things that are legal to do that aren't necessarily wise to do.
