    If I was buying an AR-15, which I do on a regular basis, Astra would probably be at the bottom of my list.

      What is the issue with them?
      (This is not the Spanish Astra, BTW)

        Ok, I thought this was Astra. Poor choice of name then…still not buying.
        I walked passed their Booth at IWA just due to…you know what.

    I just saw STG4 out of the corner of my eye and got excited, thinking someone had taken an STG44 and modernized it. Alas, another AR15

    I’m sure it is a very fine rifle though.

      No it’s not.

        What’s wrong with it? I’m sure you have extensive hands-on experience.

    So when is the lawsuit from Magpul going to start? Look at that stock, it is clearly a CTR knock off.

    • Vitsaus

      Probably as soon as it is established which parts have a patent on them and whether that patent reflects a significant departure from other designs. Also whether this design represents a major mechanical imitation of the Magpul rather than simply looking like it. Believe it or not, a lot of AR 15 stocks have a lever that you squeeze to move them back and forth on the buffer tube.

      • jnortham

        The placement of the friction lock is mostly what I am talking about. However the whole adjustment lever, friction lock and lock pin are EXACTLY like a Magpul CTR. Regardless of how it looks externally, Magpul owns the patent to the mechanism. I know a thing or two about ARs.

  • Vitsaus

    Oh look another AR15. Game changer.

    • El Duderino

      Neva ben dun befoe.

      Stock slightly different than every other stock + grip slightly different than every other grip = NEW RIFLE.
