I have itching to buy/assemble a 9mm AR platform for awhile. I see a LGS has an Olympic K9AR in 9mm for about $800. I know Olympic doesn't have the greatest rep for reliability and customer service. ( I'm not going to war with this thing but you would like to have a mfg. back up their product.) Would it make more sense and less hassle just to get the parts from Rock River and assemble one myself instead of potential headaches with Oly? Yeah, I know there would be a price difference. Just looking for NES opinions and I know they're out there. Thanks.

Not sure what magazine it takes, but for under $600, you could have a 9mm AR.

I've read that mag blocks are less reliable than a dedicated lower FWIW. Been looking at the Stag Model 9T and the CMMG Mk 9T myself. Lone Wolf also makes a lower that takes Glock mags instead of the Colt pattern SMG mags that can work with most uppers if the bolt is modified.

The Glock lower might also be a good idea for those of us in less than free states provided G26 and/or pre-ban mags are available. Seeing mixed reviews on 10rd Colt pattern mag reliability.
CMMG also has just the lower receiver sub-assembly without the LPK installed if that is more your style: https://www.cmmginc.com/shop/lower-receiver-sub-assm-mk9-smg/

i used to own an olympic 9mm. put a hahn mag well block in it, worked great. my big problem with that gun was the magazines, the thing used sten mags and i could only ever rustle up beat to shit ones older than i am. never had a problem with the rifle itself, it was always the mags.
olympic doesn't have the best track record, but it's difficult to **** up a blowback operated gun. barrel? check. recoil spring? check. bolt? check. rifle is fine.

Pistol caliber ARs seem pointless to me, but if you want a pistol caliber carbine plinker, get the Mech Tech conversion. Reasonably priced and they seem well made.

I've got one of these, goes onto my G34, put a red-dot on it and have a blast with it. Very well made, good value for the money. I was a bit surprised by the weight, it's very SOLIDLY manufactured. Slight "twang" from the stock. They call it a "CCU", carbine conversion unit; essentially an upper for your existing lower. Available for glocks, 1911's and I don't know what else at this point.

So much bad information in this thread it makes my head hurt.
I have two AR9mm's: One with a dedicated lower from CMMG and one with a Hahn mag block. Reliability has more to do with the barrel/bolt headspacing and quality magazines than the mag block.
If you decide to assemble it yourself buy the barrel & bolt from the same mfg. CMMG & RRA both have 9mm figured out pretty well. Hahn blocks are the best but you will pay for them ($200). Building it yourself won't save you money but will give you exactly what you want, just like building an AR in 5.56.
As for 10 rd Colt mags, don't bother. Colt took Uzi mags and modified them for their platform. The same can be done to existing preban Uzi mags with a dremel or machine shop. Preban Uzi mags are ~$10, plentiful, and hold 32 rounds. Why would you even look at 10 round mags?
Pistol caliber carbines are an absolute blast to shoot, cheap to feed, reliable, take the same accessories as a 5.56 AR, and are plenty accurate within 100 yards yet have less blast and recoil than a 5.56 AR. They have more in common with a subgun than with an AR15.
This is bad information. There are many companies making mag blocks and as always, some are quality and some are not.
This is more bad information. parts for AR9mm's are EXTREMELY common and widely available. I could list 10-20 website that have all necessary parts in stock ready to ship. Prices for bolts are equivalent to quality 5.56 bolts, barrels are in line, lowers perhaps slightly more expensive, and all other parts are identical in price.

I have a PSA 9mm kit set to arrive monday, and a modulus 80% lower waiting to be milled out and attached to it. This should be fun 
Only real question now is which color lower do i use it with (red/blue/black)?

Please keep us up to speed on how it works out.
I'm the first one to admit that there are 10 reasons a 9mm AR is dumb. But the simple fact is that I like shooting ARs and 9mm is a nice caliber to shoot out of one. Inexpensive, and fast to reload compared to a bottenecked rifle cartridge, but still a "real" round that can be used for all kinds of fun things like shooting pins or steel.
Just make sure you don't accidentally thread a .22 cal flash hider or brake onto that muzzle, since they both use 1/2 x 28 threads.

Really?? As I'm sure you know, every other 9mm on the planet uses 1/2x28.
Well, I guess its a good thing that ARs are threaded differently. Its probably not an accident and done specifically to avoid someone putting a .22 cal muzzle device on a 9mm AR.
Thanks. I learned something.
Don
p.s. Like I said above. I don't own a 9mm AR. But I do have a M11-9 with a Lage upper. It came with what looked like an A2 flash hider. Its threaded 1/2x 28 so I (incorrectly ) Assumed that the FH was from an AR and that all ARs followed standard 9mm threading. I was wrong.

There are still a few mfg's who use the 1/2x28 thread pitch but most use 1/2x36 so really smart people don't throw one of those fancy 5.56 muzzle devices on their AR9mm and hurt themselves.
You will find far more muzzle devices for the 9mm AR in the x36 thread pitch.
If anyone is on a budget, don't hesitate with the Hi Point 995. The only real knock is that the mags are only 10 rounds, but you're in the Commiewealth of Marxichusetts, anyhow, so...
For under $300 bucks you cannot beat it for a pistol caliber carbine.

I love the short memories of shooting enthusiasts. Very short quiz, which company, despite pleas from all over the map, insisted on making a 7.62x39 "pistol"
which directly led to the ban of inexpensive Chinese 7.62x39 ammunition?
Hint- look at company name in OP.

I don't get your point. This is about taking pistol ammo and using it in a rifle.
Not about using rifle ammo in a pistol.
When using rifle ammo in a pistol, you end up with a situation where you possess a handgun that can pierce a cops body armor.
Which has legal issues around it.
In this case you are putting a round in a rifle that can't pierce body armor. i.e. better for the cops than a normal AR.
In fact this is one of the reasons that pistol caliber carbines have fallen out of favor with LE.
The "point" is that OP is considering the acquisition of a firearm made by a company with quality issues, Customer Service issues AND singlehandedly shut down the importation of inexpensive ammunition for millions of shooters. For the sake of selling a few pistols. Despite the pleadings of shooters and others in the business.
0 stars for Olympic Arms, forever.

The quality issues and such I agree with and the same could be said of PSA. The "selling a few pistols" hypothesis is myopic and not the whole story.
Regardless, trying to appease or negotiate with the gun control politicians has proven futile at every turn. I'm not sure what makes you think Olympic is singularly responsible for getting specifically Chinese x39 import banned. That opinion focuses on a tiny piece of the puzzle rather than trying to understand what really happened. There was barely a whimper of protest to that ban as well. The gun community loves to crucify companies tat they perceive as "betraying" the RKBA or somehow blame them for gun control actions that further restrict our rights.
Why don't you blame those who actually restricted your rights in the first place? Misplaced blame helps no one.
As I have pointed out, there are far better choices for an AR9mm than Oly & PSA in terms of quality, price, reliability, and options. I would buy RRA, CMMG, maybe even Stag or QC10 before those two.

I get your point now. You weren't implying that producing a 9mm rifle would lead to a ban on the importation of 9m ammo. Which would be ridiculous.
you were simply saying, don't do business with a company that would do such a dumb thing with no regard for the repercussions over thier effort to sell a couple of thousand guns.
Message received.
In the big picture, I think the new popularity of rifle caliber pseudo SBRs using arm braces is going to cause us trouble. The ATF has shown little regard in the past for reversing its opinions and acting in a totally arbitrary and capricious way.

I have a suggestion: Chiappa has a 9mm m1 carbine replica that takes Beretta 92FS mags.
I have seen them for about $500 on gunbroker
Anyone have experience with these?
Sorry to bring up an old thread, but I was curious if anyone has any experience with the Colt AR15 9mm, or the like? I really like shooting pistol caliber carbines and want one in the AR15 format.
Again, I hate trying to explain myself to the "bigger is better" people, but anyone have any thoughts on the colt? Any other suggested AR9mm options out there?
