Will this work on the KS-47 lower?
Lee Family Arms on Apr 18, 2018
BEST ANSWER: Just Spoke to Palmetto Via Facebook and they have Said this will now work on the KS-47 Lower. "No it will not. The KS47 lower requires the KS47 upper to run"
It this upper cut out enough to let me use my Psa AR stripped lower that takes AK mags?
Brett E on May 1, 2018
BEST ANSWER: Nope, this takes an ar15 lower and mags.
Will this upper work with a 2.23 and 5.56 lower? Same idea as a 300 black out upper to 5.56 lower. Magazine too? What would I need if I bought it?
Noah R on Apr 24, 2018
BEST ANSWER: Yes it will work
Recommend heavier hammer spring 7.62x39 Russia ammo has harder primers . 223/5.56 mags will not work . Use C-products ar15 7.62x39magazines I’ve had no issues Eric B
Will this work with the classic Blackhawk lower? Or which is besr for it?
Lance W on Apr 18, 2018
BEST ANSWER: Yep, that's what I have on mine. Works great, have fun shooting it. You'll love it
How easy would it be to convert this to free floating rail? Same as AR15 upper or would the caliber/barrel complicate it?
Trygve V on Apr 18, 2018
BEST ANSWER: Same as AR. Will use same rails, uses same barrel nut, uses same barrel wrench.
Will this work with the PSA gen2 PA10 lower?
Eric M on Apr 17, 2018
BEST ANSWER: NO - PA-10 is for .308 / 7.62x51 Nato in the AR-10 platform (larger frame). This 7.62x39 upper is for AR-15 sized receiver
I tried to fit this on a standard PSA AR 15 lower and does not fit properly. Rear take down pin won’t go in,does not line all the way up have to force it down but still won’t go in. Is there a special lower for this upper?
Actionman2929 on Apr 28, 2018
BEST ANSWER: I have this upper paired to a PSA lower and the fit is flawless. Better fit than a Anderson lower. Make sure to push the upper back towards the buffer tube. If it still won't line up and pin you may have an out of spec lower(highly unlikely). Best way to check is try and pin another upper on that lower and see what happens. If it won't pin then the lower is out of spec. Also make sure the BCG is fully engaged with the barrel extension. If another upper fits fine the then upper is slightly out of spec. Just send it back and Palmetto State Armory will take care of you. Trust me.
Anyone know what the exact diameter of the bore is? .308, .309, .310 for reloading and ammo purchases?
Trygve V on May 1, 2018
BEST ANSWER: I sent an email to PSA requesting this information and they replied that they "don't have that information available". Not the answer I was looking for but that was their response.
Does this have any mods to deal with steel cases and hard primers?
Sean B on Apr 18, 2018
BEST ANSWER: it's possible to pierce brass cased primers as it comes. a standard 556 firing pin cures that on brass.
Is this avail in left hand option?
Steve M on Apr 17, 2018
BEST ANSWER: As of right now, PSA does not offer any left-handed uppers.
Will this upper fit on an ATI Omni Hybrid 5.56mm?
jimmy t on May 8, 2018
BEST ANSWER: This upper itself is a standard AR-15 type, only difference is barrel caliber. I have used PSA uppers on the OMNI HYBRID. The new hybrid is a very snug lower, but should work fine.
Will this work on any mil spec lower other than a PSA lower?
Kiely R on Apr 23, 2018
BEST ANSWER: Yes, It will work with any brand standard mil spec lower. I built mine with an Anderson lower and it fit perfectly.
Does standard AR15 buffer spring need to be changed out / upgraded - the KS-47 lower uses a PA10 carbine buffer spring wouldn't this change need to be made to prevent battering the rifle?
William on Apr 6, 2019
BEST ANSWER: I just used the standard carbine spring and buffer. Had no problems.Enter
Simple question, can i remove my 5.56 upper and install this one? What mags do i need?
Roger W on May 7, 2018
BEST ANSWER: Yes. AR-47 mags...
what is the barrel thread?
Tactical a on Apr 23, 2018
BEST ANSWER: 5/8" x 24 for the flash hider.
Will this upper work with a 5.56/223 lower ?
John S on Jul 17, 2019
BEST ANSWER: Yes with out any problems at all as long as either upper is complete with its own bolt carrier Group as will a 6.8 6.5 223 wylde 224 and the 204 as all of them are in the ar15 profile however it will require the use of a different magazine.
Will this work with a complete DPMS AR15 lower?
Chad M on May 27, 2018
BEST ANSWER: Yes it will. You will need 7.62x39 specific magazines. Also there has been some issues with mil surp ammo in these uppers. Hammer not striking hard enough to ignite primers. I have been using new issue, brass case 7.62x39 and mine has been functioning well !
Is an FFL required for the uppers?
Ronald P on Oct 26, 2018
BEST ANSWER: My upper was shipped directly to my home. The lower required FFL at my local gunshop
Is this direct impingement or piston driven?
alvarez1900 on Jun 5, 2018
BEST ANSWER: Direct Impingement carbine length system. Takes its own BCG and requires AR 7.62x39 mags but will fit standard PSA lower. Very happy with mine.
Will this work on a core 15 lower?
Chris on Apr 24, 2018
BEST ANSWER: When you say core.. I take it your saying a standard 5.56 multi cal lower. . If so yes it will work.. martin
Does anybody have extraction problems with this upper. My AR47 no longer ejects the empty casing and the case gets stuck in the chamber. Any Solutions?
Nick L on Apr 23, 2019
BEST ANSWER: If you're shooting steel case ammo the first thing I would do is remove the upper and pull the bcg out and closely inspect it if it looks to be okay I would use a larger brass brush in the chamber with a good solvent as steel cased ammo is normally covered by lacquer and it will build up in the chamber.
will this work with ks47 lower?
larri l on May 26, 2018
BEST ANSWER: It seems some have experienced functionality problems. The problem seemed to be the magazine lips and the upper. I have used metal mags and have not had a problem. Search the forums for more info.
Will the standard ar 15 Lower work with this and with AK mags?
Lou L on May 7, 2018
BEST ANSWER: Yes and NO. it works with standard AR lowers, which by the don't accept AK mags.
I just bought a PSA AR 15 MOE EPT will this upper fit on my new lower?
thank you ,
dennis g on May 4, 2018
Will this 7.62x39 upper work with any regular ar15 style lower?
Manny on Apr 30, 2018
BEST ANSWER: Doesn't work well with dpms lowers have to do some custom milling to make work
Will this work with the AR-15 stripped lower?
Richard W on Apr 20, 2018
BEST ANSWER: This upper will fit on to one of our AR-15 stripped lowers.
Will this upper fit on a mutant lower?
James A on Jun 7, 2018
BEST ANSWER: yes. Mutant lower and the lower palmetto makes for the upper are almost the same. Also works with just a AR lower if you run the AR-47 mags.
How about PSA List the Lowers that this Upper will work with? Make our shopping FUN not a pain!
Anthony F on May 23, 2018
BEST ANSWER: The description clearly states that it works with any milspec lower. You only need to get a 7.62x39 mag to accept the caliber change from .556. Lighten up Anthony. PSA ain’t nuthin’ but good.

fal1NH on May 9, 2018

Impressive with suppressed subsonic ammo.
Wanted a better pig gun with more knock down than the 300 blackout. And with the new subsonic ammo in 7.62x39 it is actually quieter than my 300 blackout.

Best value you’ll find in a 7.62X39 upper if you’re on a budget but want to have fun at the range.
Arrived in great shape, packed great! Paired up with a Palmetto Lower and couldn’t be happier. At the range, all I can say is “what a blast”. It preformed just as I had hoped. “Flawlessly”.
Thanks again Palmetto.

Solid upper and excellent build quality
PSA has set the bar with their uppers by being well made, affordable and accurate. These uppers just don't disappoint and I have had no issues thru thousands of rounds with any of them.

Wanted something to shoot 7.62x39 ammo, and this unit with 10 round C-products magazines works good for me at a reasonable price.

Makes good holes down range.
Bought it, built it, shot it, decided I don't like 7.62x39 out of an AR platform, and sold it to an ex-Marine buddy of mine who thinks that a 5.56 is a toy.

So everybody is happy!

Least costly way to get into .30cal if you want to use it often.
Wanted to get into .30 Cal, as cheaply as possible, in the same year, and be able to fix any breakages.(good luck finding PSA-AK parts) This was THE Best choice! I got it really hot, and shot to 400+yds out of the box, with a conservative holdover, and no modifications.(range boss was super pissed about me using holdovers) AR STONER mags we're so-so, but I was using 124gr hollow points(mistakenly), and soft points, and fmjs worked fine. I don't fault the mags tho. Do not do the (rumored) front cut on the mags. I am sorry now I did that(still testing theory). MagLula now makes a loader for this rifle! Get one. My Only real question is why they don't use an AR10 barrel extension to not mar up rounds on the way in, but mine feeds fine anyway so far. I am only a bench shooter anyway.
P.S. get the PSA .30 compensator before they sell out forever. It looks/fits Great!-havent had the chance to test mine yet.(I never use inside ranges, as its pointless)
Just trying out the Linb-Saver I had lying around, it's ok, but looks rediculous.

Runs great, but snapped bolt extractor.
The upper was properly assembled, and fully met my expectations. The FSP was properly aligned and the system functioned as expected. Missed 5 stars because the bolt extractor snapped with only 100 rounds through the upper. Maybe not so much a knock on PSA, but this is a common failure with x39 bolts. I will be contacting PSA for a replacement.

Didnt work at all
Wrote to PSA, haven't heard anything back yet after a full day. Will see tomorrow if I get a response. Heard these are great. The BCG did not fit. Had a 20yr cop and Range Master even verify. Will update my review when PSA fixes the issue as I am sure they will. I have purchased many items from them.
