I say: Bring on the boom boom. Use a good muzzle device. Adjustable gas block. Lightweight bolt carrier with short, heavy buffer & spring. Modern bullet construction. And, thirty .22 or .30 caliber holes poked through you will still ruin your day.
I humbly present one of the lightest and shortest AR pistol configurations you can build today, without having to resort to an unobtainium bufferless bolt carrier group.
19" OAL. 4.34# unloaded. Runs like a raped ape.

KAK 4.75" barrels (assembled pistol is 5.56, barrel shown is 300BLK). Superlative Arms AGB. Kaw Valley LC (minor milling required to fit AGB screw). Strike Industries 5" pistol buffer tube.
I put well over a hundred rounds of surplus Malaysian 556 FMJ through it last week without a single hiccup. Nice dense pile of brass over my shoulder at about 4:00. Fist-sized group at 25yds - my cheapo RDS was wandering a bit. Time to upgrade to a Holosun.
Itty Bitty Bangbang fits inside a normal sized daypack and has become my new Jeep gun. Consider it as a modern-day Streetsweeper.
Let's see your micro-pistols and hear about the details of your builds.
