    “… or similar low powered ammunition.” .22 magnum AR-15?

  • AK™

    “..low-cost”..yeah to them. For the consumer? probably in the neighborhood of $400.

  • MrMaigo

    Is it really different enough to patent?

  • Jusuchin

    Maigo: I agree. What makes it different? I mean, there is a whole slew of manufacturers out there making ARs and whatnot.

    @MrMaigo,
    I don’t think they’d try to do it if they weren’t confident they had a shot. Read the patent, that should answer any questions you have.

    Why is the magazine in the patent picture backwards?

  • Kyle

    Whoops, never ming, i just looked at the picture again and saw what I thought was the barrel was actually the buffer tube

    @Chris: They’re trying to take advantage of the current state of the patent office in the US. They are granting patents for things that should never have been accepted. This patent application should be denied for nothing more than previous art.
