  1. 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.

  2. 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 :/

    • 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?

  3. 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”

  4. 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.

  5. 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?

  6. 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.
