Discuss 9mm AR carbine as a go to

[Jpoe88]

I may scrap the project rifle I have and start filling up my parts bin with what I may take off.

How practical is a 9mm rifle? Intended use is training and trunk or truck gun. I'd like to do something budget friendly but still run. What I need is a barrel, bcg, adapter blocks and mags.

Should I run a Colt mag setup or hold out for a glock 9mm lower?

Are these reliable or only a novelty?

Money is an issue right now but I fee like I'd be at the range more often with 9mm than 223 due to cost.


Discuss please!

Coming from someone who wants a 9mm carbine or 9mm AR pistol for a "truck gun/range toy" I don't see the advantages over a .223.
I see the initial build cost advantage going to the standard AR pattern in .223 for me. (mags and plenty of spare parts around here somewhere)
Ballistically and lethality gives a strong edge to .223.
Ammo cost at $.20 per 9mm and $.30 per .223 is $100 per thousand rounds. Personally 1000 rounds a year through this setup is something I probably won't do regularly so the savings becomes a moot point.

All valid points. My buddy is reloading 9mm at .02/rd. But again that's not me

I could see how that would change things.
Kinda talking out thoughts in my head trying to decide myself.

Is he willing to ship. Dang that's outstanding.

The AR9 for me is a great build for HD in pistol or SBR. The rifles are good for competition and training. I ran a pistol with 8" barrel it's not as much flip on the muzzle. I used PSA colt mags that were always snug and I liked the bolt staying back on the last round fired. Metalform are good to go as well.

I believe he's at like .06 using factory fmj, but .02 for cast

I'm thinking light, simple and cheap. Willing to bet I can part out my rifle and have enough to build it. Considering with a FSB as well.

I was too but I also want it functional. Im not the builder type. I was thinking CZ Scorpion but it's just an idea I'm tossing around

the last time i purchased them, psa colt mags were metalform mags but rebranded by psa.
