Palmetto State Armory .308 AR-10 Lower Receivers

Palmetto State Armory has finally released their new PA10 AR-10 .308 stripped lower receivers. The retailer known for their budget priced AR uppers and parts kits actually showed off their new AR-10 rifle at SHOT Show 2014 earlier this year. They also showed off two new prototype 1911s at SHOT Show that they’re working on as well. The new PA10 lower is made out of forged 7075-T6 aluminum and is hardcoat anodized. It has an integrated trigger guard and accepts SR-25 type magazines. They’re retailing for $159.99 but Palmetto is currently only allowing customers to order a maximum of two lowers. Just a note, because I know this will be brought up in the comments. If you do order one be prepared to wait a little while, although Palmetto State Armory is known for their killer deals, they do take a little while to ship out. Check them out at

Made using the most advanced aerospace manufacturing technology to produce the industry’s finest forged .308 lowers, our receivers are machined on an automated multi-million dollar manufacturing system which enables us to produce a product of unequaled quality and value.

These forged lowers are quality made using 7075-T6 aluminum. The finish is black hardcoat anodize per MIL-8625 Type 3 Class 2. Additionally the receivers include an integrated trigger guard, and are designed to use AR15 fire control groups so your favorite AR class trigger can be used. These are developed for use with SR-25 pattern magazines – which are commonly available in metal or polymer.

  • That’s an LR-308 not an AR10.

    • Renegade


      I am under the impression that AR-10 is a generic description, an LR-308 is a DPMS product, and the PA-10 is the PSA product. I see a PA-10 stripped lower pictured above.

      • This lower does NOT use the armalite AR-10 pattern so calling it that is completely false. This lower uses the DPMS LR-308 pattern which is why I called it that. I don’t think PA is calling their product an AR-10, only the writers here are.

        • Anonymoose

          We’ve been over this before. There are a lot of companies that still call their .308 ARs “(company designation)-10” to differentiate from their “(company designation)-15” .223/6.5/6.8/etc models. This has only led to confusion among consumers, and it would make more sense to use “-25” for rifles using KAC/DPMS mags, like Remington does with their R-25 series. The “AR-10” currently manufactured by Armalite doesn’t resemble an original 1950s vintage AR-10 at all, and is basically just a copy of the SR-25 (which started out as an AR-15A2 stretched to use .308) with proprietary mags. The LR-308 was the next really successful .308 AR platform to come out, and is basically just a cheapo version of the SR-25, which almost every other company making “-10s” copied. Bushmaster used to make the BAR-10, which takes metric FAL mags, but they sold the patents to Rock River who still makes them as the LAR-8.

          • Rusty Shackleford

            I remember the Bushmaster (Windham) BAR-10. Since the AWB has been lifted it just doesn’t make much sense now for RRA and has been an incredibly slow seller. I wish RRA would upscale their LAR-PDS platform for the .308 cartridge and have it accept Pmag/Sr-25 mags. Now THAT would be a nice competitor to the Scar-17/HK417/Sig716 especially if it is at a better price point.

          • Stan Darsh

            Great, now you’ve got me drooling at the thought of a Rock River Arms LAR-PDS in a .308 chambering.

          • LilWolfy

            The BAR-10 was always RRA’s design. They licensed it to Bushmaster since Bushmaster had capacity to make it. Its magazine arrangement was also totally based on Clinton AWB arbitrary restrictions, and it became an irrelevant solution the moment the AWB expired.

            I think RRA could be sitting on gold if they wipe the table clean, and design a new AR10 with their bolt catch assembly, using SR-25 mag compatibility. Shorten the receivers up significantly like the GII and Colt 901, cut that beastly weight and horrendous length, and you have a winner.

        • dan

          Remember when there was an article about a .308 lower and then all you nerds could talk about was what pattern it was? Seriously? You want to be “that guy” bad enough to flame the author over his what is very common mistake just so you can appear smarter. If I wanted to buy the lower I am not going to jump right to their website and blindly buy it without figuring out if it is what I really want. If I did then I deserve to end up with the wrong part.
          You people are the reason I hate gun people you are like trekies say one wrong thing and bam! Flame war. Just shut up and get over yourselves.

        • LilWolfy

          It’s an AR-10 lower. Nobody makes an original, authentic Hollywood or Dutch ArmaLite AR-10 lower, upper, BCG, barrel, handguard, extension tube, LPK, buffer, charge handle, or other parts associated with a “real” AR-10. The closest to come to that in recent times was an AR10 being developed by Saber Defense before they were shut down by ATF. It had the original pattern BCG, which was shorter, an original AR-10 pattern large diameter extension tube, but with modern design for the upper, LPK, etc.

      • John

        Nah, up until recently I thought the same too. The .308 ARs are a surprisingly whole different world than the lego-style mix and match AR-15s. There are big, incompatible differences between brands and larger swings in quality.

    • Christian Hedegaard-Schou

      Yup. I’m surprised a firearms writer would get this wrong. AR-10 is trademarked by Armalite and used to denote their own .308 Stoner/AR variants which use different upper receivers and magazines from the rest of the industry.

      And while AR-10 has become somewhat of a colloquial term for any Stoner rifle in .308, it’s still wrong.

      LR-308 or AR-308 is the term that’s generally correct to use to refer to a non-armalite AR/Stoner rifle in .308, especially if it accepts DPMS/KAC pattern magazines.

      • It’s just become common usage these days.

        • Lee

          These gun nerds like to whine about the most minor of stupid details.

          • John

            I remember on MAC’s channel someone demanding that Tim refer to his rifle as a Colt 6920, not as an AR-15… or the countless demands to refer to AKs as AKMs or AK-74s

          • rdsii64

            Colt lost the trademark on the term AR15 because they didn’t defend it. Just as any company can build a 1911 type pistol and call it a 1911 for the same reason. Cold didn’t defend the trademark. With the popularity of both of those guns, that was a mistake on Colt’s part.

        • BattleshipGrey

          Kind of like people calling tissues “Kleenex” or the South calling every soda known to man as “Coke”. When someone says AR-10, we know they’re talking about .308 ARs.

          • rdsii64

            EXACTLY!! Now if you really want to hurt their brain tell them that the DPMS REPR and the LR308 are more faithful reporductions of the Stoner design than todays ‘trademarked” AR10. These purists seem to forget that Todays SR25 was desined by Eugene Stoner while he worked at KAC. While your’re at it, remeind them that todays Armalite isn’t the same Armalite from 1957 which was a division of Fairchild aircraft. If you are feeling really mean, remind them that todays trademakred AR10 isn’t the same rifle as the Stoner original.

      • LilWolfy

        Only problem is that Colt actually owned the patents on the AR10 that they bought in 1959 from Fairchild-ArmaLite, and then Colt immediately began tooling up to manufacture their AR10A before being told to stop and tool up for the AR15, after potential foreign customer feedback heavily favored the AR15.

        The Colt AR10A had an angled magazine like the Mark Westrom 1996 AR10 later introduced during the Clinton AWB. The post 1996 AR10 is actually heavily modeled after the 1993 KAC SR-25, with major deviation only being in the magazine, and minor design changes in the BCG.

        SR25’s use the original ArmaLite magazine and receiver interface, since Stoner designed the SR-25 himself when working in conjunction with Reed Knight II.

        The only reason the new ArmaLite used M14 mags was because of the Clinton AWB. They could no longer make more than 10rd capacity mags for civilian sales, so they had to use surplus mags already in existence if they were going to offer standard capacity. ArmaLite also used the KAC SR25 upper/lower angle cut and fit. Their rifle basically is an SR25 that feeds on modified M14 mags.

        DPMS totally deviated from any receiver commonality with the LR-308 by making an AR15-style radius cut in the rear, while using the KAC SR25 BCG and magazine well design in 2004.

        In the end, these are all AR10 variants, and Stoner would recognize them as such. The argument that the Eagle Arms/Mark Westrom AR10’s are the exclusive .308 AR’s of that nomenclature is rather silly, especially since the BCG’s and barrels can interchange between all 3 designs.

        • rdsii64

          AMEN BROTHER!!!

      • rdsii64

        If todays Armalite were the same company as the oringinal division of Fairchild Aircraft that would mean something. in 2014 armalite is a completly different company. For what its worth, the modern SR25 rifle (not todays trademarked AR10) was designed by Eugene Stoner himself while he worked for Knights Armament Corperation. Todays trademarked AR10 is Not a Stoner designed rifle but designed by todays Armalite. Todays trademarked AR10 is also different from the original Stoner designed AR10. So actually what is correctly refered to as an LR308 or an SR25 pattern rifle closer to the Stoner design than todays trademaked AR10. Refering to large format AR rifles as AR10’s is akin to calling any tissue a klenex or using the word xerox as a verb. Not technally correct but you know what they are trying to convey.

  • Renegade

    I’ve had success with PSA’s AR products. I’m gonna have to consider this.

  • hking

    Until they start selling LR-308 pattern barrels and bolts this wont matter much. You can already get a Aero 308 lower for the same price (with a much nicer finish) or a Aero upper/lower combo for $300. If they can produce decent BCG’s for under $200 and barrels for sub $300 it would be a great start.

    • CA.Ben

      These lowers are actually made by Aero and rollmarked PSA. This is an Aero lower.

      • hking

        While the lower itself is produced by Aero, Palmetto has a different finish applied. The Aero finish is darker and smoother sort of glossy, the Palmetto finish is rougher and lighter sort of matte.

    • Stan Darsh

      I’m sure they will be releasing BCG’s and barrels shorty.

    • LilWolfy

      They do have complete uppers now, but I personally have a very difficult time taking an AR10 seriously at these price points, simply for the fact that it tells me no engineering, testing, or extensive vetting of the product has taken place, and it seems that these are relying on fitting together only.

      Correct function, balancing of the gas and recoil systems, balancing of the ejector and extractor assemblies, correct reaming of the chamber for a gas gun, total quality management of the critical dimensions of the BCG, heat treating, materials science, etc. all come together to make a reliable gun.

      Companies that spend the money to accomplish this price their rifles at 2-4 times these price points. The receivers themselves should be ok, provided a corresponding lower parts kit will interface with them correctly, but the critical pressure-bearing parts and operating system parts need to be engineered, not cheaply copied with AR10’s.

  • big daddy

    And what compatibility does it have with uppers? The PSA upper is also being sold and what compatibility does it have with barrels & BCGs? PSA doesn’t say on their web site. They being all the companies made a huge mistake with the .308 AR type rifle in not having a standard like the AR15 family. It could have been a HUGE seller on the market but this has held it back and will continue to until they come up with a standard and stick with it.

    • Rusty Shackleford

      True, although The SR-25/LR-308 is as close as the industry has come to a standard. Hopefully the DPMS Gen II will become the new standard.

    • LilWolfy

      There is no standard for AR10’s, and there never will be. There is no TDP that manufacturers can look at or copy, because there are so many different designs.

      It is in a company’s best interests to be able to keep control of the design, parts, and magazines of their rifle, since anything else is out of their control. Once you try to be compatible with everyone else, you need to open up a call center to handle the endless complaints and trouble-shooting requests you are going to get, and that’s a total waste of money, as you have no control over what deviant parts customers smash together, expecting miracles.

      • big daddy

        It looks like there are more and more companies following the DPMS pattern. Right now as far as I know DPMS, Bushmaster and CMMG are all in spec with each other to be able to use their parts interchangeably. DPMS and Bushmaster are the same rifle as far as I know. I’m seeing more and more parts for the DPMS pattern. In fact because of the modularity of the design it is in the best interest of a company to make parts that fit one pattern. There have been some problems with PSA stuff as far as I know. I suggest you go to forum. For that reason of parts interchangeability and modularity the industry will pick one pattern. Probably the DPMS since it is supported a small amount by the military and a big company like Magpul who makes magazines that fit. Even though the magazine is such a small part of the overall rifle cost dictates that the difference between a $20 magazine that works and scrounging them having to modify magazines makes a huge difference in being able to market any rifle. If the .308 is going to be accepted for the tactical aspect you need parts that will work consistently and be 100% reliable. More and more people are looking to the AR in .308 to take up where the 5.56mm leaves off. Next year I am going to try and put together an AR in .308 if parts become more available and it looks like they are and in the DPMS pattern.

        • LilWolfy

          I’ve been tracking the AR10 before the SR-25 came along, when all there were on the market were original Dutch ArmaLite pre-86 guns and parts kits.

          DPMS actually took a big departure from the 1993 and 1996 offerings by KAC and Armalite by making a deviant upper/lower fit, with a different upper receiver thread pattern for the barrel nut.

          DPMS no longer exists as the company we once new, and the brand name and assets were sold to Freedom Group as you know. Freedom Group has actually done the best thing for the AR10 market with the introduction of the GII this year at SHOT. That rifle design just made all the 1993-2013 designs obsolete in terms of receiver and BCG size.

          Having felt, handled, and shot the Dutch ArmaLite’s, I always wondered why the modern guns don’t feel as well as the 1950’s guns when looking at balance and weight. The GII feels better than the originals even.

  • PatrickHenry1789

    If I’d known I was going to start reloading i would’ve bought a 308 instead of a 30-06. I’d love to build one of these.

    • iksnilol

      If it is a bolt gun then you can shoot 308 from a 30-06 chamber. At least you can do that with Mausers.

      Search around though, I could be wrong.

      • LilWolfy

        Nope. That’s a disaster waiting to happen. Both .308 and .30-06 headspace from the shoulder location to the bolt face, and they are drastically different from each other. If you were to light off a .308 in a .30-06 chamber, the gases would escape back around the case into the action at tens of thousands of psi, since you don’t have a good seating of the shoulder anywhere near the neck area.

        • iksnilol

          Theoretically, it can blow up. True. Practically? It has never happened so far. I don’t do it, but I have seen some people do it.

          Then again, we do call the 308 casings without neck “.30 caliber idiot”.

          Reason it works in Mausers is because the casing is held by the claw extractor… or something. I am no Mauser guy.

  • Noel

    Can anyone tell me if this lower takes the DPMS barrel?

    • LilWolfy

      There is no interface at all between the lower receiver and barrel or barrel extension. The upper receiver is what the barrel is mounted to, and the upper attaches to the lower. From customer feedback, the PSA receivers are not compatible with DPMS receivers, so you need to purchase both PSA upper and lower to have a rifle that fits together.

  • rdsii64

    The new DPMS GII puts them all to shame anyway!
