[Review] Palmetto State Armory (PSA) AR-10 in .308

Can you really get a reliable AR-10 .308 for $600?

Palmetto State Armory (PSA) aims to make that a reality.

I test out their AR-10 in .308 (other calibers coming soon) across 6 types of ammunition, multiple magazines, and hundreds of rounds.

Find out if it passes the reliability and accuracy test!

Who Is It For?

  • Budget buyers who want something that works out of the box that doesn’t always turn heads or shoots half MOA.
  • Someone who wants some options in terms of barrel length, gas system, and handguards
  • Someone who can wait a little for things to be in stock and ship

Why Is It So Cheap?

If you don’t know yet…PSA is known to be the market leader in affordability.  They get that way since they own all the companies that take raw metal to the finished product.

They sent me this AR-10 to fully test out after my review of their AR-15s.

PSA 5.56 & .223 Wylde

I test it the same way as I do with all my other guns.  And actually increased the types of ammo through the AR-10 since they are known to be finicky with the gas system.

Fit, Feel, & Finish

Upper

I opted for the shorter 18″ upper in stainless steel for a little lighter weight compared to the 20″.  If you’re strictly bench or prone shooting you can get the 20″ for a little more velocity.

You can see, like in my previous reviews, sometimes there’s a color mismatch of the handguard to the receiver.

Not a deal-breaker for me but keep that in mind.

The lightweight 15″ M-LOK handguard was nicely machined and didn’t have any sharp edges like some in their AR-15s.

The barrel looked good and had a centered and tightened gas block.  It normally will come with a flash-hider but I switched it out for a .308 compensator I had lying around.

Lower

Colors and fitment match pretty well.  Nothing much to write home about.

PSA AR-10 Upper and Lower

Like their 9mm AR (full review), the pistol grip holds in two detents…the normal safety detent plus the rear takedown pin.  Much easier for install!

PSA AR-10 Lower, Double Detent

My biggest complaint with my lower is that the takedown pins are SUPER tight.  Even after so many installs/removals for break-in…I still have to use a screwdriver and hammer every time.

The lower originally came with PSA’s EPT trigger which is surprisingly crisp compared to mil-spec.  But the above is a Triggertech I swapped in for accuracy testing (Best AR Triggers).

You can also check out their 2-stage trigger ($99) which is great for the money.

Magazine release works well and sometimes the mags were a little tight to get in…but always dropped free.

So far so good…especially for around $600.

How Does It Shoot?

Boom!  Let’s get down to the important stuff…

Break In

I broke the barrel in during a trip to BLM desert land while setting up for night vision (Best NVG Goggles).

Author All Geared Up with Carrier and NVG

I usually don’t do break-in for AR-15s but since this is more of a precision gun…

  • 5x: 1 shot, copper remover, wait 5 min, bore brush, gun cleaner, clean patch

Recoil

A lot more than the 5.56 AR-15 if you’ve never shot a .308 semi before.

You’ll often read that PSA overgasses their AR-10s.  I think that’s a fair statement.

I broke in the rifle standing up and after those 30 or so rounds I was definitely feeling it…this rifle is more meant for bench shooting or even better…prone.

There’s no adjustable gas-block so you can’t tune down the amount of gas heading back into the BCG.

Reliability

Bummed that you can’t tune down the gas?

One good thing is that being overgassed makes it more reliable.

The AR-10 ate up all 6 kinds of ammo I threw at it…from the cheapest brass ammo I could find, to regular plinking ammo, and several kinds of match ammo.

The bolt always held back on empty with both my Magpul and DPMS magazines.

For reliability…PSA’s AR-10 was great.

Accuracy

I really hoped the accuracy was going to be good…especially since I spent a lot of time breaking in the barrel.

I set the rifle up in my standard testing rig…now with a chronograph.

Testing the PSA AR-10 .308

100 yards, slow shooting with each group, and about 5 minutes to cool down before the next group.

And used a bunch of my favorite .308/7.62×51 ammo (Best .308 Ammo)

PSA AR-10 308 Groups
PSA AR-10 308 Groups

The MEN, PMC Bronze, and PPU were my plinking ammo…and it looks like PMC Bronze did the best with probably 2.5 MOA.

For match ammo…Hornady’s 168 BTHP didn’t do as well as I had hoped.

But Federal’s Gold Match in both 168 and 175 gr were excellent at around 1.5 MOA.

Here are the average velocities for each ammo out of the 18″ barrel:

  • MEN: 2622 ft/sec, std deviation: 16 ft/sec
  • PMC Bronze: 2644 ft/sec, 6.5 ft/sec
  • PPU: 2634 ft/sec, 6.4 ft/sec
  • Hornady 168 BTHP: 2593 ft/sec, 7.7 ft/sec
  • Gold Medal 168: 2459 ft/sec, 10.8 ft/sec
  • Gold Medal 175: 2447 ft/sec, 14.4 ft/sec

Long Range

100 yards is great and all…but chances are if you’re looking at a .308 you want to stretch its legs.

So I went to my local rifle range and set up with a bipod (Best Rifle Bipods).

And at the very back…my 600 yard targets.

I shot off the bench in a reasonably comfortable position.  No rear bag though…I did forget it.

Video: I hit 9/10 with the 175 gr Gold Medal…and super cool to see the vapor trails!

Not too shabby for my skill level…if you’ve got the range and the skills you should be able to hit out to 800 and even 1000 yards with a .308.

Compatibility

AR-10s in general don’t play that nicely with each other.  So if you’re going PSA…stick with both PSA upper and lower.

Aero M5 .308 AR-10
Aero M5 .308 AR-10

The newest generations are Gen 2 but even if you have a Gen 1 lower…it will still work with a Gen 2 upper.

Functional…but a little weird looking.

Recommended Models

There’s not nearly as many models of the AR-10 compared to PSA’s AR-15 offerings.  But it’s ok…you’re pretty much choosing between free-float and going either 18″ or 20″.

If you’re strictly bench or prone shooting…get the 20″.  Otherwise if you want something a little lighter and maneuverable…get the 18″ like me.

I also go for the free-floating variety…especially for a long range precision rifle.

Those are the complete rifles…but if you know PSA…the deals are to be had by separating the upper and lower.  That way you avoid the 11% completed firearm tax.

My specific upper which I recommend is the 18″ Stainless with 15″ Lightweight M-Lok with BCG (bolt carrier group) and CH (charging handle) for $499.

While the lower I would heavily recommend getting a better buttstock that has a nice cheekweld.  The one I have is the Magpul MOE STR but the ACS-L is also great.

The EPT is a nice upgraded single stage trigger while the Nickel Boron 2-Stage trigger is PSA’s version of Geiselle’s SSA-E trigger.  Great when I tried it out on their 6.5 Creedmoor guns (review coming soon).

Possible Upgrades

The PSA AR-10 is a great beginning platform for long-distance shooting.

One of our readers even sent in his build…thanks Derek!

Reader's PSA AR-10 Build, Courtesy Derek B.
Reader’s PSA AR-10 Build, Courtesy Derek B.

He has in his 20″ PSA AR-10:

  • ATI X1 Grip
  • Smith Enterprise Vortex flash hider
  • Radian Raptor charging handle
  • Burris PEPR Mount with Vortex Viper 4-16x
  • Harris bipod

His AR-10 gets 1-1.5 MOA with 165 gr Nosler Ballistic Tip and 1 MOA with Remington CORE-LOKT in 150gr.  I’ll have to try those loads out next!

By The Numbers

Reliability: 5/5

Besides really tight takedown pins…the AR-10 performed flawlessly with 6 kinds of ammo, 2 types of magazines, and hundreds of rounds.  Overgassing gives it the reliability at the expense of a little more recoil.

Accuracy: 4.5/5

OK with the cheapest plinking ammo and decent with PMC Bronze.  But great with Federal Gold Match in both 168 and 175 gr flavors.  600 yards all day long for me.

Ergonomics: 4/5

Handguard feels much better than PSA’s AR-15 models.  Otherwise everything is where it’s supposed to be.  Make sure to get a better buttstock with a wider cheekweld.  Your long distance shots will thank you.

Looks: 3/5

It is what it is…the handguard is a little mismatched in color from the upper and lower.

Customization: 5/5

It’s an AR platform with M-LOK so you can do anything to it.  I easily added in a new trigger, compensator, M-LOK rail, and Atlas Bipod.

Bang for the Buck: 5/5

GREAT deal…especially when the next comparable/affordable maker is Aero Precision and theirs is $1400.  Full review here of that one.

Overall Rating: 5/5

Conclusion

Long Range Testing PSA AR-10
Long Range Testing PSA AR-10

A great AR-10 that didn’t give me the problems of other platforms.

And at an unbeatable price that’s about half the price of the next closest competitor!

There’s some coloring issues in the handguard and you’ll have to deal with it being overgassed…but for the price there’s no complaints from me.

    PSA just dropped their Gen 3. Added adjustable gas block, NiB 2 stage trigger and went with STR stock. $900 as complete rifle or $700 if you buy the built upper & built lower seperate. Based off the site info I can't find a difference between the fully built rifle vs the built upper/lower. Looks like you got a new review to do.

    Excellent article as always, Eric. Lots of us worked hard and long, but for various reasons have a tighter budget than most, so these kinds of reviews are SO helpful. With a little luck and time, sometimes we can step up to something more expensive later but if this is the caliber that's most useful for someones wants and needs, they can get going and get accustomed to recoil, general range capacity, what sights will hold up, etc. Plus, ultimate accuracy has it's place without doubt, but in many scenarios 1 - 2 MOA or so variation won't matter much. Thanks for the review.

    I have two PSA ar-10 one in 308 and one in 6.5 both shoot great 1 moa at 100 with hand loads. the 6.5 came with an adjustable gas block with the 20'' ss barrel. I have seen no need to adjust it so far. The 308 is fixed gas block and I have shot a good bit of surplus ammo from Korea, us, and Israel. no functioning problems and us issue groups are better than some of the commercial ammo. I also have shot and reloaded for an Armalite for the past 15 years. The ar-10 is in 308 with a lightweight rifle barreled upper with a free float handguard and I also have a short heavyweight barreled upper. both of the Armalites are finicky about the ammo they will run reliably and what they will shoot accurately. I have to give a heads up to the pair of PSA

    I have about 13 or so PSA lowers that I have either built on or plan to build on. 3 ar AR10s. 2 are .308 and 1 is 6.5. I buy PSA uppers for most applications. I have 2 uppers from ar15parts.com. 1 is .308 and the other is 6.5 grendel. They build using PSA and DPMS uppers. Have you tried them or even heard of them? I have gotten real good results with their hbar barrels. I do not know who manufactures the barrels.

      Craig, I read in one of the gun mags a year or so ago that PSA barrels are all made by FN, who is just down the road from them do to speak.

        Only the CHF barrels are made by FN, PSA makes the rest of their barrels in-house.

    The distance question is tough. I was @ a 1,000yds class and my sister-in-law was using a Ruger Precission .308 with a 20" barrel. All was good to a out 800yds, then she started running out of elevation on the scope. She hit 1,000, but it took her 6 tries and got the instructor involved. Ammo selection is also an issue. FEDERAL GMM 175grMK got the job done. The caliber is certainly capable of 1,200, but not sure you will get there with that 18" barrel.

    Thanks for the review. PSA always intrigues me because of their deals. I'm also stuck behind enemy lines. Did you order the lower from PSA with the CA-compliant grip factory-installed? If so, was there any surcharge for changing the grip, or any special process to order it like that?

    2 months ago
    • David, PPT Editor

      We added the CA-compliant grips ourselves, PSA won't ship them that way. Best way for CA to get PSA rifles is to get the parts and just build it out yourself. More time and effort, but well worth it!

  • Pascal Roberts

    Would you recommend this over the aero m5? They both seem to have the same level of accuracy. Seems like m5 just has more parts compatibility with other 308 ARs and has a slightly nicer build quality?

    I've been in the market for an AR styled brush/hunting rifle chambered in 300 BLK, 6.5 Creed, or .308. Right now I shoot a Kimber bolt action .280 AI, which is by far my favorite cartridge. Would this be a contender to consider? PSA is only 40 min west of me, so it would be nice to "Buy Local".

    • David

      I think the PA-10 in 6.5 Creedmoor is what you're looking for. 6.5 Creedmoor is slightly better than .308 Win and very close to what .280 AI is like.

    Having never shot an AR style rifle, and being very interested in this particular rifle, I was wondering how they are for left handed shooters? Opinions/experiences? Thanks

    1 year ago
    • greg

      Check out Stag Arms, as they have affordable left-ejecting small and big block varieties. In fact, I believe they slot in between the PSA and Aero the author mentioned. AND have a lifetime warranty which is pretty much unheard of in the industry.

    • Joe L

      While, I cannot speak of the AR-10, I do know that a number of left-hand AR-15s are on the market(both as upper receivers and complete rifles). Beyond that, it is very possible to shoot a right-handed rifle in a left-handed manner. My brother can't see very well out of his right eye, so he has to shoot rifles left-handed. You might need to wear a long sleeved shirt or jacket as the spent rounds will be ejecting towards your support arm. If you end up choosing a right-handed AR(which tend to be less expensive), the main thing you'll need in order to shoot it left-handed is an ambidextrous selector switch. If the rifle doesn't come with one, you can get an aftermarket one for not a lot of money(~$15).

        Doesnt sound too bad. I cant do very much right handed so I have to, and naturally, shoot left handed. Thank you for the info.

    Thank you very much for the great review! Have been eagerly awaiting this one, and breath still held for your opinions on the 6.5 CM and .224 Valk PSA offerings. I’m a major PSA fan, I’m a sucker for great deals. One thing I’d ask; I recently saw an online dealer with S&W free float flat top M&P10s for $700-750. Has anyone on your staff fired one, and can you compare the accuracy/precision, reliability, recoil, and overall value of this PSA rifle vs. the S&W? I have completed my immediate AR-15 collection, with a DMR-esque build, several standard 16” carbines, and a 10.5” pistol. A reasonably priced AR-10 is next on my list. Also, I’d suggest a picture guide on how to install an adjustable gas block on a factory (free float) rifle. All of my PSA AR 15s (and a few much more expensive examples from other major manufacturers) have come somewhat uncomfortably over gassed, but I’m nervous about replacing the existing gas block with an adjustable because I’m not 100% sure what to look out for/pay attention to. Thanks again.

      Hey Connor, I'll ask around if anyone has shot the M&P 10 but I haven't (yet). Good tip on the adjustable gas block install. We don't have a standalone article but it's included in our How to Build an AR-15 Uppper article.

        Is taking the original gas block off similar to how you install one; just take out a few set screws?

    Is that rail a compression=type (only held on via compression from the two screws)? I can't see any anti-rotation tabs on there either. Basically looks like a Matrix Aerospace compression rail, if MAS made AR10 compression rails. If that is the case, that is definitely one area PSA was able to save a bunch of cost.

      Yes, looks like it unless I lost the anti-rotation tabs when I took it off.
