Advice for 9mm PCC? Have AR Rifle Lower to build up and ideally would like to use Glock Magazines

[Shellbackitup]

mixing a few things here:

A lower reg'd as a rifle can never be a pistol - the difference between a pistol and a rifle is barrel length and buttstock vs. brace. You had referenced "PCC" and that is a term used typically to describe an AR Pistol (<16" barrel, brace etc) that shoots pistol calibers, at least thats always what it means when I have heard it. If someone is building out a rifle, they usually just call it an AR9.

The freedom mag restriction applies even to rifles, but has an exception if you build it as a featureless you can use the standard cap mags without an issue.

THAT explains it!

For me, I'm a HUGE carbine guy.

But when I say carbine I just mean a short rifle, like my lever actions, pump actions, and bolt actions with a 16" to 20" or so barrel which are all pistol calibers, or my Mini-14 and Mini 30, or SKS carbine, etc.

An AR rifle to me is already a carbine.

But a PCC was a term I'm somewhat new to. I assumed it encompassed all my pistol caliber lever action, pump action, and bolt action carbines.

I didn't realize in it's common usage that it meant an AR Pistol.

Thanks for the education!

EDIT: Now I'm even more confused, as ISPA says PCC's are rifles with a stock.

So is an AR Pistol not considered a PCC in competition, but is a PCC in common parlance? I'm getting some bad info somewhere

Problem is, I don't have any AR's to begin with.

This is my first AR, and it's sat in parts in a box for many years since I mainly shoot pistol calibers and lever actions.

So all the benefits of the same motions, using mag pouches, etc. doesn't really apply to me.

I never built up my first AR because I was never a huge fan of the platform, even if I did get my ribbon with E in the Navy.

I figured using the AR Lower and Glock magazines that I already had would be a good solution.

I'm finding out it's likely not a good solution, or at least not one that anyone here seems to use or like.

Adding another magazine like the exomag is a possibility, but then I'm limited to 10 rounds.

You can use an adapter and your Glock mags but the finer options from Mean Arms or CMMG won't work.

What is your priority here? The cheapest / easiest way to get started with an AR pattern PCC or to build a nice shooter with some kind of delayed operation?

I've never heard that, especially because USPSA PPC division requires it be a rifle. This can mean that its an SBR in states where that's legal but it can't be a pistol.

My goal was to build a 9mm AR with the existing AR rifle lower that is sitting in my closet.

Since I own many std capacity Glock mags, I thought I might be able to use them.

I thought I could get an adapter for the mags and a 9mm upper that works on a standard AR lower, and wanted to see what people's experience was, and what brands they have used and like/don't like.

yeah, really I'm just referencing what Ive been exposed to when I have heard PCC referenced...which isnt worth much, beyond explaining why I immediately thought about building out a an AR15/ 9mm Pistol. lol.

Got it. I can't be much help if that's the route since I have no experience using a Glock mag adapter for standard AR lowers.

honestly , I would just try an adapter and see what happens. I know there's one in the under 100$ range.

I wanted to build a featureless 9mm carbine using my legally owned standard capacity Glock mags.

I have a featureless AR9, all it is: Ruger Complete AR lower, Palmetto State Armory 16" complete upper https://palmettostatearmory.com/psa...-13-5-hex-m-lok-railed-upper-with-bcg-ch.html , swapped the flash hider for a thread protector, swapped the grip for a Fin, and a strike industry stock stop for the adjustable stock. Currently running 10 Rnd Exomags, did debate getting the stern and running Glock mags but i don't own any other Glock mag firearms. There are cheaper ways to build one but i wanted simplicity, and the LRBHO works on the PSA upper. Running exomags you will have an easier time swapping uppers if you were to share the lower for multiple configurations.
