Palmetto State Armory 9MM AR15 Pistol Kits

A few months pack Palmetto State Armory released their 9mm AR15 rifle uppers and build kits. Those were cool and all, but what I and I’m sure many others out there want is a pistol kit. Well Palmetto State Armory must have read my mind because they just recently released their new pistol kits. Starting at $549.99, their build kits include everything needed to build an AR15 9mm pistol minus the lower and magazines. They even come with the second generation Sig SBX Brace. Check them out at

  • Oh, man, I’ve been looking for a 10.5″ 9mm upper for my DDLES build. Hopefully they’ll release a upper-only version soon!

  • Ralphie

    It figures someone would come out with a reasonable priced AR in 9mm after I just completed my AR 9mm build. This caliber is a blast to shoot in an AR platform, just don’t expect dead nuts accuracy at long range distances like would expect with a rifle round.

  • thedonn007

    Is the bolt ramped? Also, they need a version with a 4.5″ barrel. I do like the fact that this barrel has been nitrided though.

    • Vhyrus

      4.5 seems a bit short. 7 or 8 would be awesome though.

      • thedonn007

        I am not sure what happened to my last reply. However, I had stated that a 4.5″ barrel is a good length for use with a suppressor to keep it subsonic.

        • Ethan

          Even without a can that would be a useful length. Same approach as a micro-uzi: smaller is better in some cases.

  • All it needs now is a LAW Sidefolder and you’ve got a handy little blaster.

      That’s the 16″ version

    Looks tasty

    I’m sorry but just about the only thing I can think of that would be sillier than an AR-pistol would be a pistol-caliber AR-pistol. An AR-pistol is simply a way to have an SBR without the obscene tax stamp and even more obscene paperwork, but when you make it in a regular pistol caliber all you have is an enormous (and ridiculously expensive) pistol that doesn’t handle worth a darn.
    Just my opinion — feel free to flame all you want.

    • Ethan

      Not flaming, but you do understand what a submachine gun is, don’t you?
      Yes its not FA, but the concept is still very effective. Small, light, easy to deploy, easy to shoot, better precision than a pistol with greater capacity.

      • Tom Currie

        You do understand that a submachinegun is a TWO HANDED weapon and the FA capability is at the heart of its usefulness. Yes, you can use two hands on an AR pistol (and most of us do even though apparently we are legally not supposed to) but still a pistol-caliber AR pistol combines all the negatives of a pistol and a submachine gun without any of the positives.

        I guess the world has come full circle because I can remember being handed an AR in 1969 and thinking it was a halfway decent machinepistol (while cursing the idiot who decided to have it replace a real rifle).

        • Ethan

          We are allowed to use the AR pistol in any way we see fit – shouldered, two handed while doing a back flip if you so choose. What the ATF considers it I don’t particularly care.

          FA is the best, but a decent trigger (read anything better than the standard Mil-spec) puts rapid semi-auto at a close second. Proper training can largely make up the difference.

          I won’t try and say a 9mm pistol is the best SMG alternative, but there isn’t a lot of good options on the market right now.

          If someone wanted to make an UZI with a Sig Brace, or the CZ EVO3 comes out, I think that will be a better alternative, but until then this is a good option for all the reasons (except FA) that SMGs exist.

  • Grindstone50k

    Oooooh, the wife would be really interested in that

  • echelon

    Tempting…but now that they announced the CZ Evo I think I’ll wait. By the time I bought this and another lower and all that I’d be in it for about the same money and I’d have *another* AR…

    • Ethan

      Both sexy options, but I have to agree – The CZ EVO3 takes it by a significant margin. Cheap mags, great ergos, and the potential for a fire-while-closed side folding brace put it firmly in the WIN column.

    Believe Jesus Christ is your savior for your sins. Jesus Christ is God Almighty in the Flesh. This is the Gospel, believe Jesus Christ shed his precious blood and died for you and all of your sins on the cross, he was buried and he rose again from the dead three days later from God’s Power and you will be saved, you are a Born Again Christian and you will go to Heaven forever. All have sinned and fallen short of the glory of God to where we all deserve death, destruction and judgement in the Lake of Fire from the wrath of God to where we need a savior to save us for our sins forever. By receiving Jesus Christ’s blood sacrifice as full payment for your sins you will be saved forever. It matters not how much you have sinned in the past, in the present and in the future. Once you are saved you are saved forever no matter what. Good works will not ever save you and no one and nothing else will. That is the Gospel and if you believe in the Gospel you are now a Born Again Christian and you are now saved and you will go to Heaven forever and that is the whole truth. Spread the truth. All glory goes to God forever! Praise God! Amen! (John Ch. 3:16, Romans Ch. 3:25, 4:1-6, 5:9, 1 Corinthians Ch. 15:1-4, Ephesians Ch. 2:8-9) The Authorized King James Version Bible.

    Why is that a deal breaker? I’ve beat the ever living crap out of Magpul polymer rails and not had any issues…don’t see why the ones on the Evo would be any different unless CZ uses inferior material or something, but I’m wouldn’t be too worried about that being that CZ has a reputation for making quality products.

    To each their own I guess! Good luck with your build if you find something. I personally have never seen an AR pistol with a barrel shorter than 7.5″. I could be wrong but I believe it has to do with energy to cycle the bolt. But I’ve not done much, if any, research on pistol caliber variants so maybe with a blowback style 9mm the shorter barrel would be ok…

  • Tom Currie

    Who needs double tap? Oh yeah, I forgot, we were talking about 9mm, so I suppose you do need to double tap.

    • Ethan

      So you’ve gone from complaining that it can’t shoot fast enough to complaining that you’d have to shoot more than once….
