The Gen2 PA10 receivers are functionally compatible with the Gen1 receivers, however we recommend matching Gen2 lowers to Gen2 uppers for best appearance.  There are external cosmetic differences when mixing gen1 and Gen2 upper and lower receivers that some may not find appealing.  

The AR10 platform does not enjoy a common design between manufacturers, like the AR15.    As a result, there can and will be subtle differences in the parts kits of various manufacturers.  Some parts, like the fire control group, are shared with the AR15 platform to preserve the options for upgrading.  For best results, we recommend only using PSA PA10 parts with our uppers and lower receivers.  We do not recommend using other manufacturers parts in our products.

Are there left hand models available?
Sean E. E on Jul 9, 2018
Will this work on some other brand upper?
Vergel P on May 23, 2018
BEST ANSWER: Because there is no "mil spec" for the AR-10, there is no "benchmark" to compare brands to. The PSA lowers and uppers are, to my knowledge, proprietary to one another.
Can I ship to Palmetto State Armory?
Big John on Aug 20, 2018
Riley on Oct 1, 2018
BEST ANSWER: The trigger guard is permanent on this lower, but it's very nicely contoured. It reminds me of the m-lok guard on my pa-15.

Michael B on Jul 3, 2018
BEST ANSWER: It says PSA 10 Multi.
Can I put a rifle buffer in this?
Garrett J on Oct 21, 2018
BEST ANSWER: No. Unless you change the buffer tube out to a rifle buffer tuber then you can.
It says to use with PSA uppers. I know there's no mil spec, but AR and DPMS. Will it work with my existing Aero Upper DMPS or any other DPMS upper? Or PSA uses some proprietary tech?
Eugene on Jan 28, 2019
BEST ANSWER: It’s a tight fit for any upper that is going on a psa lower. I have a aero upper and I had to bite down pretty hard to get it to fit. But after shooting it a few times it’s working it’s way through to fit better
Will this lower for a aero precision m5 upper?
Jbg1015 on Nov 22, 2018
BEST ANSWER: Will work with any 308 upper that I know of
Is that 7.62x39mm ,or 7.62x51mm?
Daniel F on Aug 11, 2018
BEST ANSWER: The receiver says .308 so the PC answer is only .308. However, to answer your question, 7.62x51mm

Goosegod on Jan 4, 2019
BEST ANSWER: Correct. I bought this complete lower and bought a complete upper from them and put put them together and went to the range. I have no issues with either. I love it. Enjoy!
If i buy a complete lower and upper will that be a complete gun?
Arthur I on Feb 7, 2019
BEST ANSWER: Almost complete, you will still need a box magazine and sights/optic. Be sure to choose a lower that has the appropriate weight buffer & spring to work with the length of gas system on the upper.
will this work with a davidson defense upper?
Justin U on Feb 21, 2019
BEST ANSWER: I have not tried it with a Daniel defense upper. I have tried it with a PSA upper and a Armalite upper.It works fine with both of those. If you’re up or is mill spec I feel it will work

Josh W on Aug 7, 2018
BEST ANSWER: Yes, both the .308 and 6.5 creed use the larger AR10 platform instead of the AR15 lower that is more common for 5.56/.223.
Can you install an AR15 ambidextrous safety?
jeffrey d on Dec 19, 2018
BEST ANSWER: Yes. It uses standard lower internals. Only difference between AR10 and AR15 trigger groups is a larger hammer to prevent light primer strikes on the harder mil surplus primers. Trigger and safety are standard. In fact you can run drop in AR15 trigger groups if you are shooting commercial ammo.
Mail spec or commercial?
Jackson P on Oct 20, 2018
BEST ANSWER: It looks like mil spec to me, I thought it said mil spec on the advertising when I purchased this lower. Have had no problems with this lower since I purchased it.

Ben A on Jan 25, 2019
BEST ANSWER: This can be used for 308 as well as 6.5, in fact, that is what I am doing, getting the upper for the 6.5 to add to this and from everything I have gathered uses the same mags.
Which calibers ,besides .308 uppers,can I attach to this lower?
Fabricio on Jan 10, 2019
BEST ANSWER: Any AR10 caliber complete upper will work from Palmetto, However Ar10s are not as interchangeable as AR15s. I’d use a Palmetto State stripped upper if you are building a rifle to make sure all is well. Some other uppers work, but lines will be off, some other will not.

Frank C on Dec 14, 2018
BEST ANSWER: No, The diamondbacks have an armalite style upper.

Good bang for the buck!
I purchased this lower a few weeks ago and at the same time purchased and married it to the,PSA Gen2 PA10 18" Midlength .308 WIN 1:10 Stainless Steel 15" M-Lok Upper with BCG & CH - 516447164. Fit and finish at first was pretty impressive but then as I began working on the weapon I realized it would scratch a little easier than I would expect or want. But, it is still nice. Upper and lower mated great with no issues! Barrel threading was a problem though. When mounting a Lantec Dragon it was way off for the crush washer and it took a great deal of work to get this new break on and seated properly. I have installed these breaks on many different brand AR15 and AR10 and this was the first time I ever had a problem! Getting past that I did make a few other changes. The trigger that comes with the lower is mil spec and relatively no better or worse than you would expect but still for long shot, it is pretty darn bad! I replaced it with a Huperfire trigger I already had and now I am a happy camper on the trigger. I added Diamondhead iron sights and a Meopta scope with a Larue mount. Just for S&Gs I highlighted the logo and some other engraved parts of the lower. Does not do a thing to make it shoot better but it does add a little pizazz to the rifle. Also added a BADD ambi selector and a upgrade on a magpul grip and stock. It was raining but I still wanted to try her out so I went to the range. Set up on a hundred yards and was happy that with no break in, I was on paper right away. I ran for rounds total, 20 each of 147 gr boat tail Winchester and 147 gr PMC ball all with no failures. Too much weather to work on the sight so that will come in the next week or two. However, seeing I was on paper and consistent with the first 40 rounds at this distance I can say I believe for the money spent, this is a pretty darn good shooter. I wish the QC would have a better handle on threading the barrel and I could give this another star.

I built a 6.5 Creedmore on this receiver and the upper and lower were tight. The lower parts kit installed without any problems. I have fired this new rifle and the lower is working as expected.

Incredible rifle for the price!
This is my first PSA rifle. I Bought 2, Paired both with the 18 inch upper. This rifle has been fantastic. I ran 50 rounds through both right out of the box without lubricating them. Ran another 50 rounds through them after lubricating the bolts and Carrier Groups. Picked one to spray paint and that one I shot another hundred rounds through. So thats several hundred rounds with zero issues in 2 rifles. The gas system setup is fantastic, I don't think you could get these things to fail to eject if you tried. So far I've been able to feed it everything, my 7.62 NATO and 308 everything from heavy and slow to light and fast the only thing I haven't tried is subsonics... it chambers every time.

Out of the box I'm shooting about 9" or 3 MOA at 300 yards with 1982 Surplus military 308. I blame this mostly on the trigger, which to be honest is not bad at all but it's not a 1000 yard trigger. I'm also using a bipod on my picnic table in my backyard not a sandbag so a new trigger along with sandbags and I'll be shooting close to 1 MOA which is impressive for this price. A 2.5 or 3.5lb trigger with a new muzzle brake and perhaps better cheek weld and this rifle can shoot 1000 yards.

In conclusion right out of the box you get minute of zombie shooting out to 500 yards and with another few hundred dollars spent you will get minute of zombie out to a thousand yards. Incredible value! I can't believe I waited this long to try PSA.

Not too happy with CS
I mated this lower with my PSA upper. The bolt catch was impeded by the upper ever so slightly. The bolt would not lock open I called customer service and considered sending the lower back but while talking with customer service they offered to send another bolt catch assembly for me to drop in. So far so good. The CS rep said they get it in the mail that week. Two weeks go by and I call again to inquire about the shipment, naturally at this time the assembly is out of stock, but they assure me they'll get one from somewhere and send it off, you guessed it, by the end of the week. Yesterday I called to see the status again because the end of the week came and went. Yesterday I was told we will get back to you by the end of the day via phone to let you know when you can expect us to ship it. Yep, no phone call. I just called again and basically am being promised now it will be set up for shipping today. I assume they're breaking down a completed upper to salvage an assembly to ship to me.

I get the fact that there are going to be problems from time to time with items. What I don't get is the runaround I received. I have spent close to $1000 with PSA this year without an issue and I generally am happy with what they deliver.

In the meantime, for me to adjust the gas block I filed down the catch where it was being impeded by the upper in order to hold open on an empty mag. I didn't really like the alternative which was filing on the inside of the upper. So I was able to adjust it enough to cycle consistently. But the locked open condition is pretty fragile, one decent bump and it will close.

Pretty good for the price
Wanted a 308 to hunt with and I really like the customization of the AR platform. PSA prices couldn't be beaten. Trigger pull is a little heavy and the take-up is typical of an AR, But the break is clean and crisp. Oiled the moving parts and pinned a PSA Gen2 upper assembly to it (yes, there was some rattle, but a foam earplug under the rear lug solved that) and she runs flawlessly. The only issue I have is, Hexmags fit very snug and don't drop free....I think I can deal with this one flaw.
I'd recommend to anyone wanting basic quality at a fair price.

very good value for AR-10 lower
I added an expensive trigger and an expensive buttstock from another vendor. I paired the upgraded lower to a PA-10 rifle-length upper. The PA-10 lower is a well-made vehicle ready for upgrades of your choice. Fit and finish are very good. All dimensions are in-spec. Otherwise, the basic buttstock and the basic AR-type trigger that it comes with are, well... basic. Do yourself a favor, and put a better trigger and buttstock on it.
