Go "Squatchin with your AR!
I just haven't heard much about it at all as you've said. I wouldn't think it would be something that draws in many new users, but I've been wrong before.
Once again: Why do people NEED AR's, not want them. Your own family feels that a handgun is better for their defense than the gun.
As for your shilling - You have gone on about it's price, accuracy, and easy modding.
On the picture, this says it better than I can. Though I do worry about the source and any bias they might have had beyond the post below.
