    I’m seeing an AR pistol that takes glock mags, not a Glock receiver.

    1. avatar Kevin says:

      I agree! I was expecting an upper that slides onto a Glock 17 frame.

      “FM9 Glock Small Frame Billet FM9 Pistol Lower Receiver” is a fancy way of saying, “It’s an AR pistol that takes Glock mags.”

        “I was expecting an upper that slides onto a Glock 17 frame.”

        Now that would be a great thing to see.

    How long until the ATF re-rules these as forbidden?

    1. avatar L says:

      If the ATF ruled pistols as forbidden they’d start the third American civil war.

      1. avatar Joel says:

        Was the second American civil war written out of the history books or something?

        1. avatar Simon says:

          2nd Civil War, commonly known as the Civil War. The 1st was the Revolution.

        2. avatar L says:

          Simon is correct.

      2. avatar Rusty Chains says:

        L, not use to seeing Lincoln’s war described that way, but it’s an interesting way to look at it.

  3. avatar MouseGun says:

    So, is it a chassis that makes a Glock look like an AR? Is this so you can operate while you operate?

  4. avatar Defens says:

    Until I looked closely, I assumed that the lower receiver perhaps was AR compatible on the outside for the grip, but had internal Glock parts somehow. But nope, standard AR safety, trigger, hammer pin locations.

    So other than Glock mags, what’s so Glock-ish about this? It isn’t even blocky and generic looking – actually looks kind of nice.

    1. avatar TruthTellers says:

      Not sure, but the lower receiver may be polymer.

  5. avatar Texican says:

    Wait, the whole enchilada is only $549?! Shut up and take my money!!! Only thing that would make it better is 10mm!

    1. avatar Alex Waits says:

      Flightlite “MXR” is what you seek for 10mm AR pistol

  6. avatar john says:

    I wish TTAG wouldn’t post this stuff. What is a “Glock framed” lower? You don’t even bother explaining. It just looks like an AR pistol with Glock mags :/

    1. avatar Joel says:

      I think what makes this different is it’s designed from the ground up as a 9mm AR pistol maybe? That’s my best guess.

      Most of the 9mm ARs look funny to me. Mag well is extremely disproportionate to the size of the mag etc.

      If it’s really under $600 then I’d buy one.

      EDIT: it also looks like it’s blowback operated. Is that true for most 9mm ARs?

      1. avatar Mall_Operator says:

        Yes, the majority of 9mm ARs are blowback operated.

  7. avatar possum says:

    I too believe these will be BATFE targeted firearms .I’m beginning to apprehensively fear that much tolerance and acceptance is going to be needed to retain ones life and process firearms in the near future. … ” Your perception of an unjust law is just that! It’s your ‘perception’ of THE LAW as unjust”

  8. avatar New Continental Army says:

    Liar liar pants on fire.

  9. avatar FreakinPeanuts says:

    meh… i dont want a large 9mm pistol unless it folds. and can fire from said position.

  10. avatar Sora says:

    BS! PSA has been selling PSA-9 for a long time.
    Just another AR with Glock Mag openings. Better to get full AR with adapters for different mags.
    Only thing new here is side charging handle. But that’s an upper thing.

  11. avatar Ironhead says:

    I want one. Put a brace, buis, mrds, and a light on it and it’s perfect.

  12. avatar Mideastbeast says:

    Why why why hasn’t Glock seen the obvious demand for a “Glock Carbine” yet? And we thought they were dragging their feet on producing a 9mm single stack….

    If Glock made their own carbine for an MSRP of <$700 or so it'd be an instant hit. Just look at the Ruger PC carbine.

  13. avatar Ardent says:

    Misleading marketing much? I get that they want to differentiate this from something manufactured as a ‘rifle’, but a “Glock lower receiver ” this isn’t. It’s an AR pistol that accepts Glock mags without modification…but it’s purely an AR lower just the same. By this logic an AR factory built to accept M14 mags would consist of an “M14” lower and a proprietary .308 upper.

    Part of the beauty of the AR system is that the two ‘halves ‘ of the weapon are separate, facilitating not just unparalleled modularity, but a whole paradigm of ‘upper’ and ‘lower’, which has lead to some interesting derivatives, such as this…why deny this in the marketing?

  14. avatar rt66paul says:

    Actually, buying into firearms that may be NFA items in the future could be a profitable idea. If the supreme court says that they can not take them away, you could get grandfathered rights and the value would go up.
    Not a scenario I want, but if I wanted it, I would buy it and use it and not worry about what could happen.
