Palmetto State Armory Glock Mag AR15 Lowers


Palmetto State Armory recently debuted their new AR15 Lowers that accept Glock style 9mm pistol magazines. They have completely assembled AR15 lowers in both rifle and pistol configurations available. The new PSA 9mm lowers are machined from billet 7075 aluminum T6 forgings and have a hard coat anodized finish. Palmetto State Armory also uses their own lower build kits, a classic A2 grip, 6 position buffer tube and M4 style stock. The pistol configuration will include a PSA pistol buffer tube and no stock obviously. They retail at just $239 over at

The only downside is they were designed to work with Palmetto’s 9mm AR15 uppers and bolt carrier groups, not sure why they wouldn’t work with other 9mm uppers however. AR-15 lowers that make use of popular Glock magazines are nothing new, New Frontier Armory actually debuted their own billet Glock mag AR-15 lowers at the low price of just $169.99 for a stripped lower and $289.99 for a complete lower a few months back. There was also the Angstadt Arms UDP-9 Glock Mag 9mm Pistol that was shown off at the 2015 SHOT Show in Las Vegas, Nevada earlier this year. And there’s also the Quarter Circle 10 GSF in .40SW that we posted back in April.

    I know glock is the go to brand but to use them as a hunting arm (deer) it must be at least equivalent to a .357 magnum in most states. Why not set it up to use Coonan Arms mags or maybe even Magnum Research mags which would be more versatile. If it must be glock then 10mm or 40s&w should be an obvious choice, otherwise you are marketing a one trick pony paper puncher/defense oriented gun. I understand the “pair it up with your side arm” movement but I want one that could still classify as a sporting arm.

    • BattleshipGrey

      Correct me if I’m wrong, but I think you only have to meet or exceed the .357 magnum bullet diameter (maybe that’s what you meant). Lone Wolf offers uppers in .40 and .357 sig. Aside from paper punching, I think this type of offering would be a great home defense weapon due to the lower pressure 9mm compared to 5.56. I think the AR platform is quickly becoming the rebirth of the subgun and PCCs.

      As for actually making on in .357 mag, I think that’d be sweet. I just checked prices on Coonan’s and Magnum Research’s magazines. DEFINITELY go for the Desert Eagle mags, they’re $40 vs. Coonan’s at $60!

        Some states use a “reasonable caliber”. If the deer is dead, it was a reasonable caliber. Idaho, last I checked allowed ANY center-fire caliber. A 4 inch .25 ACP qualified the last time I checked.

        • John

          “Reasonable” isn’t the same as “humane”, “efficient” or “effective”.

          Actually using .25 ACP on anything larger than a rabbit–for anything other than immediate self-defense or post-apocalyptic hunting–is incredibly stupid

          • Kivaari

            I wont use a .25 for anything. Idaho allows any center-fire round. Washington state, last I checked used a “reasonable” standard. Before that a .25-35 Win. rifle was not legal, but a .25-35 pistol was. A .45 Colt wasn’t for long time, until they instituted a testing program to see if your ammo met the threshold. It became simply stupid. Now, well 9 years ago when I left, it was the “reasonable” standard. After all a man with a .357 he just killed a deer with, certainly had a reasonable caliber he used to kill the animal. A hit with a .357 is better than a miss with a .44 magnum.

    • Kivaari

      Because using the Glock magazines means more people will buy them. There are a handful of Coonans on earth. There are millions of Glock 9mm pistols everywhere. Most people wouldn’t consider hunting with them. A carbine or pistol in 9mm would work for deer in a crisis. I doubt many people would buy these as a hunting arm.

    • boardsnbikes

      Your “sporting arm” purpose might be satisified because Quartercircle 10 Glock-compatible small frame lower receivers support 9mm, .40 S&W, and .357 Sig while the large frame lower receivers support 10mm and .45ACP.

    • Griz

      Just curious why you wouldn’t use a rifle upper for deer? With 300 Black, 6.5 grendal, 6.8, .450 bushmaster, .50 beowulf, etc… or if you want to hunt with a pistol AR why not use a 300 black out with 9 inch barrel? Not saying a pistol carbine wouldn’t be fun in the woods but in the world of AR there are lots of options and you only need to pull 2 pins.

    • Anon. E Maus

      Because Glock 33rd magazines are very reliable and easy to find.
      Not all 30 round 9mm magazines are reliable or readily available. Also, think of it like this, if you already have a couple of stick mags for your Glock 17, you wouldn’t have to buy new magazines for one of these.

      I imagine you could take deer with a 9mm AR if you have a long barrel and have a really hot and heavy load. It’s on the milder side though.

  • Cymond

    I think this is huge. We have yet one more competitor in the Glock-mag-AR market, driving down the price. I made a list of Glock-mag carbines a few years ago, and it was a short list (not the highest quality, either). I’m thrilled to see the field expanding.

    Seriously, a few years ago, there were only a few PCCs. Now it seems like they’re everywhere!

    • USMC03Vet

      I wish this was the case for AK 9mm versions. Good grief are those things expensive. AR guys got it good with calibers.

      • KestrelBike

        Needs more bizon clones/magazines.

        • DW

          you meant Vityaz. Bizon uses helical mags and proprietary handguard; Vityaz uses standard AK handguards and “gastube”(not krink)

          • KestrelBike

            Vityaz is hot for sure, but I dig the helical mag of the bizon. In fact, I bet Magpul could copy/produce such a magazine if the wanted to (although it’d be such a niche product as to make the idea pure fantasy)

      • Anon. E Maus

        Yeah, the AKX guns are amazing, but they’re just ludicrously expensive.

    • Cal S.

      Still not a huge fan of PCC ARs/AKs. I’m of the bent that if you’re going to go to the trouble of a full-length and full-weight rifle you may as well fire a rifle cartridge. That’s why I’ve got a Sub2k…

  • Kivaari

    I like it. An SBR would be a nice package. As a pistol, not for me.

  • ozzallos .

    Dat buffer tube.

  • DIR911911 .

    and they’re out of stock

  • Old Gringo

    Great idea…..I had a marlin 9mm campers carbine and it would shoot 1/2 inch groups at 50 yards, beyond that they would yaw and by 100 yards groups were like 6 inches…but for coyote calling or plinking or just fun a 9mm AR with a suppressor would be great….my Marlin used SW magazines which was a plus…the Glock mags are cheap and the Asian made copies are dirt cheap and they work well so this is a grea idea..can anyone supply a link to buy the complete 9mm upper with a threaded barrel?

  • John

    Excellent. Now there’s a reason to own a 33-round Glock magazine.

    • Nashvone

      I thought pissing off the anti-gun people was reason enough.

    • Vizzini

      Owning even a Glock 26 is reason enough to own a 33-round Glock magazine!

    • notalima

      Having just finished my New Frontier Glock lower build I happily found that a 33rd mag and 17rnd G17 mag consume one box of ammo quite conveniently 😀

  • Nicholas Chen

    Interesting. I just finished building a 9mm AR for a trade. And I liked it so much I am thinking of doing it again but this time Glock rather than colt mags.

  • schizuki

    I wish someone would make a side-loading upper receiver so you could have a 9mm with a standard lower. Seemed to work well enough for Bergmanns/Stens/Sterlings.

  • I’m not sure how these Glock 9mm receivers will work, but I have had excellent success with PSA upper receivers and products. I’m excited that PSA has entered the 9mm carbine market. They make excellent products and incredibly affordable prices.

    PSA has a contract with fellow South Carolina business resident FN to make barrels for their upper receivers, and the results are outstanding!

  • Koh

    Do these have last round hold open like the Quarter Circle 10 Glock mag lowers?

    • notalima

      With some cosmetic differences these look (functionally) like the New Frontier Lowers (Have not seen an ‘above’ shot so I am not 100% certain). The New Frontier does not. It requires a special upper for LBHO to work. And I don’t know exactly how that works.

  • Christian Hedegaard-Schou

    Would be nice to have a large-frame glock mag lower so you could rock 10mm mags.

    There’s enough custom upper manufacturers out there that sourcing a 10mm upper is easy. The lower is the difficult part.

    • Cal S.

      TNW Firearms has a 10mm carbine; one of their Aero Survival Rifles.

  • thomas

    Now if this was 10mm I’d be on it.
