I put a lightweight AR pistol together last fall using a 10.5” DD upper and pistol lower. You will definitely not carry this like a handgun though. You are not going to get much lighter and while this feels light compared to a regular AR with a rail, it weighs a ton compared to something like a Glock 19.
But, it sure is a nice shooter and is one of my favorite ARs to shoot.
Do you definitely want 223/5.56? Lots of caliber options, including pistol calibers.

Can you show me?
9/40/45 are probably the most common caliber options for a PCC, otherwise about any AR caliber can be done as a pistol as well.
What are you thinking you will use it for?
What do you consider lightweight?
hiking....lightweight...lots of fire power....maybe that new Ruger
I really doubt you want an AR pistol for hiking. A very light AR pistol is going to be 5 lbs. or more. My hiking revolver (329PD) is about a third of that.
It's admittedly not as much firepower, but ounces count big time in hiking, and you've suggestions a lot of them.
A 10.5" barrel on an AR shooting 75gr bullets still gets over 2300 fps. That is around 880 ft lbs of energy at 15 feet. Times that by how big the magazine you are carrying. Remember there are 10-100rd mags for AR. That can decide the weight factor as well.
If I build one it will be for Home Defense. Maybe carry it in my Truck to work in case I run into one of them mountain lions we have in my area or 2 lagged animals.
