Pistol-Caliber AR: What's the point?

[pmarc]

So if I wan the feel of an AR, but can't shoot 5.56, this is a great option.

Grant, what would be a good manufacturer to get one in .40 ?
I guess I can only have a 16" barrel.

If anything, glock magazines would be OK, since probably the accompanying pistol would be glock too.

Why would you ever want one in 40???

Why would you ever want one in 40???

Because, in the Sovietic Republic of Brazil, no peasant is allowed .223/5.56.
Also, for you to anything bigger than .380 (even rifles) you have to be registered with the People's Army and be subject to their exacting (mostly confusing) standards and rigorous (mostly annoying) periodic inspections.

Also, despite the laws being the same for 9mm and .40, the bureaucracy mades it nearly impossible to have/transport/buy anything in 9mm, requiring additional forms and approval from up the CoC that isn´t required for .40.

Mind you, I´m a civvie, with no criminal whatsoever. If I were a criminal, I could have an 5.56 AR and/or a 9mm pistol , whatever.

So, my only hopes of even getting something AR lies with a .40 or risk buying the .22 that is available here.
If I could have 9mm, a Colt it would be.

My only other option of having an AR would be to immigrate to the US. Can you offer me a job?

This is pretty much exactly the kind of rig I'm thinking of getting. What are the details on the build?


Okie John

Ok let's start from the front and work our way back.
#1(newer)YHM Cobra M2 suppressor with a Gemtech multi mount adapter to take the place of the piston.
#2 ADCO 5" barrel threaded 1/2x28
#3 Spike's Tactical 7" BAR Rail and Magpul AFG 2
#4 Troy flip up BUIS and a Trijicon RX30 Amber 6.5 MOA dot sight
#5 Rock Rivers 9mm receiver
#6 Rock Rivers 9mm BCG ramped/purchased from ADCO
#7 LMT Tactical charging Handle
#8 Double Diamond Law enforcement lower Built up buy them and custom engraved.
#9 Sprinco extra power buffer spring and a Vltor A5H4 Heavy Buffer.
#10 A mix of C Products mags and Metalform mags. Both run just fine..
Runs like a Swiss watch..
I love this little weapon..

I have a S&W 15-22, which if nothing else is a damn fun gun to shoot, and dress up like the big boy ARs. I also shot a steel plate shoot with it, with good success.

I will have as of tomorrow a Colt 6450, mainly for these reasons:

1. Nice addition to my black rifle collection
2. Will be fun to SBR
3. Hopefully my girl will shoot it
4. Can use it at the steel plate as well
5. Ammo variety in a carbine for SHTF...
6. Can shoot it at the indoor ranges here

I'm sure there are more. I do realize that there not a ton of practical uses for a 9mm that a 5.56 can't do, but as a non-primary weapon, I will get good use out of it.

What about a .22LR. I think that will be my next rifle build.

Why a 9mm AR?

Virtually zero recoil/easy to shoot well
Barrels last forever
Low flash
9mm is cheap compared to 5.56, and good 9mm (HST, GD) isn't too bad either
Suppress very well (especially with subsonic 9)

Why not?
To be useful, they really need to be SBRs
9mm terminal ballisitcs pale in comparison to 5.56 ballistics
Decent soft armor will generally defeat 9 (if that is pertinent to your employment), which can be a pro or con.
9mm will generally penetrate more interior walls than 5.56
9mm ARs can be finicky princesses
Don't expect them to compete with a 5.56 gun past 100 meters.
Troublesome zeroes (application depending, see above)

I wouldn't lose any of my 5.56 guns to get a 9mm AR, but I would not mind having one for the wife/gf/whatever and general shootin fun.

I'm working on a 9mm upper build, which mag system is preferred for the 9mm uppers? I've read all sorts of things but it seems to come down to the Colt mags are the well regarded mag. Thoughts?

I have EXTREMELY LIMITED time with 9mm uppers.
I do not own any, nor do I have any friends that own any.
The ones I was exposed to were owned by a foreign military unit that I shot for giggles.
I am completely unqualified to give technical advice on them.

FWIW- they were Colts, modifications unknown, pretty sure they were all Colt mags, no stoppages in the 2 or 3 hundred rounds I pushed, unknown suppressor and mount.

The Colt pattern is the standard. Colt magazines were made by a company called Metalform, and again, are the gold standard for 9mm magazines. CProducts are hit and miss, if you get some that work, never sell them. If they don't, keep trading them out with the company till you get some good ones. That may be impossable as the company is out of buisness now. Modified Uzi mags work great to, but you will lose the BHO feature as the followers are not made for it. As they can be had cheaply, once modified they will work great (M60Joe on the Uzitalk.com site is a good person to have modify them). You can make the cut yourself with a dremel, not hard and several YouTube vids to walk you thru it. ProMag plastic magazines are for target practice. Poorly made and shitty materials make for one to avoid like the plague. Lone Wolf Distributers is marketing a lower which will take Glock magazines. This is a great thing but again, you'll lose the BHO if that's important to you. The bolt must also be machined to clear the magazines geometry.
