Will this fit on other lowers- New Frontier, Spikes, etc- or just PSA? Is there any ammo it won't fire?
Arvin on May 14, 2018
what else will I need to make this function properly on a 223/556 lower?
robert g on May 3, 2018
BEST ANSWER: You'll need to install a Glock magazine well adapter and an ejector. The placement of these is going to need to be accurate otherwise you'll end up with a lot of malfunctions. There are kits available to help. You'll also want to change the buffer and buffer spring to one that works with 9mm, it's not absolutely necessary but it helps with reliability. It'll be a slightly lighter spring and heavier buffer. Your lower will no longer work with other calibers unless the magazine is compatible with the adapter you installed, or you remove the mag adapter and ejector.

Honestly you might be better off just buying a dedicated 9mm lower. After all the work you'd need to do with your standard AR lower, the price won't be much different and you'll lose compatibility with your other upper.

Hope that helps. Happy building!
Does this have last rd bolt hold open ?
Michael R on May 2, 2018
BEST ANSWER: The last round bolt hold open option is entirely based on the lower and or mag block that you use and type of magazine.
Does this have a function forward assist? Or is it just for cosmetic show?
Alex L on Jul 18, 2018
BEST ANSWER: The forward assist button is functional with the claw and spring, however the hybrid bolt does not have notches for the claw to engage, so it does not function. I have built several of these platforms and with the straight-walled 9mm case, have not had feed/chambering problems where the forward assist has been necessary.

Can standard AR handguards be used with this Upper? If I wanted to swap out the handguard.
Robert L on Jul 16, 2018
BEST ANSWER: I don’t see why you couldn’t. There is no gas block since it’s a blowback systemand from what I can tell it is a standard upper receiver. I haven’t changed one out but I don’t see why you couldn’t. I will add that the Midwest Indistries rail on it Is much better than I was expecting so I kept it on there.
How do you add a surefire light to this upper?
LaneM on Aug 17, 2018
BEST ANSWER: You'd need an adapter to mount it, that's MLOK compatible. Make sure you check the diameter of your flashlight, 30mm and 1" aren't interchangeable but some mounts include an adapter.
Is the flash hider permanently attached or can it just be unscrewed?
E W on May 21, 2018
BEST ANSWER: It can be removed. I think it's 1/2x36 thread.
Is a Spikes 9mm BCG compatible with this upper and a spike lower?
Susan P on May 17, 2018
BEST ANSWER: I put it on a JBO Spartan lower (that's the same as New Frontier). No issues.

Great buy.
I like the length and especially the slimmer handguard. I went back and forth for a while on the length, but i am pleased with the 10.5. Like all the PSA product i have purchased before, the quality is above average. I have only put about 75 rounds through it so i cant say much about it yet.
Dont make fun of my red dot. It was what i had laying around extra.

Lots of fun
I bought this upper along with PSA classic 9mm colt style lower.

It is a lot of fun, the upper looks and felt nice. It is well built. Worth every dollar.
The lower, however, has a problem on the ejector. It failed to eject every time. I found out that the ejector was not aligned to the BCG well. i had to use some tool to bend it tower the notch of BCG a bit.

I love this 9mm 10.5" upper! So glad I bought it
I love this little upper. The 10.5" is a perfect size for a pistol AR build I think because I have long barrel pistols already not in AR platform. This thing is absolutely bullseye accurate at 50 yards with an Ultrashot reflex sight I have on it. I haven't shot it out much further than that because it's just fun at that distance and to chase a self healing target down range with it is just as much fun.. I really like the handguard and it's never given me any failure to feeds or failure to ejects the whole time I've had it. I've put over 500 rounds through it so far and it's my bedside protection with squidgrips and a comfy MFT grip and a sig pistol brace... great buy!

Fun to shoot
The upper works well and is fun to shoot. The only problem is the bolt length of travel and I have had a case get stuck in a void that is behind the mag well. Does not hold open unless you manually press the catch, not on the last round. If you want a neat plinker that appears to be well crafted, I can recommend. I wouldn't say the design lends it well enough to count on if your life depends on it. I got one because it was an oddball.

Flawless upper
My lower setup: a Spartan AR-9 Lower from Joe Bob Outfitters (same as New Frontier, Spikes); Milspec LPK; PSA enhanced polished trigger; Kaw Valley 8oz buffer w/ 308 carbine spring; ETS 31rd mag & Magpul 17rd mag. I put 200rds of Winchester "white box" brass ammo; Winchester Forged Steel cased ammo; and Federal alum cased ammo. I put 5 rounds of each brand in the magazine. It fired all without any malfunctions. I loaded 15 rounds of each brand per magazine, fired all 3 brands without any malfunctions.
I had a FM-9 upper (Foxtrot Mike) with the side charging handle. That only fired the Federal ammo. It didn't like any Winchester ammo at all. I would mix in the brands in the magazine and it will just shoot the Federal. Not even a dimple in the primer of the Winchester.
Overall, this upper is awesome. It fit in another lower manufacturer other than PSA. I would recommend highly to a friend. $319 is a very good price. I'm just wondering if it'll take a 7" barrel. Don't hesitate to get this for your AR-9 build.

Love this upper.
Love this pistol. I shoot this thing way more than my other ARs. Grouped 4” at 100 yards free handed with a red dot.
