I have a sickness. Symptoms include picking up random AR parts when I find decent prices on them. Today it was a Spike's stripped lower. Anyway, I like the AR rifle. Have several, all configured differently for different purposes like varmint shooting, HD, carbine classes, etc. I want to like the idea of an AR pistol. The downside I keep going back to is the size of the finished handgun. Conversely, it's a small package for 5.56mm Those that own and shoot them, what real use do you find for them? Are they just range toys? I'm not committed to a build yet, and seriously undecided between building a pistol (partly because of the cool factor) and building a rifle in one of the heavier calibers available for the AR. Rifle pro's and con's are dime a dozen with internet research, but I haven't found much on pistols. Opinions, please.
