    It’d be nice to see them offer an 11.5 inch 5.56 ,.300 BLK or 7.62×39….the latter two would get me to buy one. Or both.

  2. avatar James Banish says:

    I am all for self defense. There is only a question of practically. I love novelty guns, they are a lot of fun. I not on board with it being a self-defense weapon.

    1. avatar Baldwin says:

      OK, I’ll bite. Which of the above described weapons are inadequate for self defense?

      1. avatar Anymouse says:

        A 12″ .308 is a flamethrower, not a rifle. 7″ is a bit short in 5.56 for the same reason. .300BO would be fine at 7″, but they chose longer for some reason.

        1. avatar Green Mtn. Boy says:

          I was having a difficult time understanding their barrel length choices as 300 AAC sweet spot is 7.5 to 9″ and personally I wouldn’t care for a 5.56 any shorter than 10.5″,but that’s just me.

        2. avatar strych9 says:

          They probably figured most buyers would suppress the pistol and SBR it.

          At least that’s what I figure. .308 pistol seems like a bit much for most people. 5.56 makes sense with a 7″ suppressor on the end of it.

      2. avatar Gadsden Flag says:

        None are actually inadequate, but there are many that are better it begs the question: Why?

  3. avatar possum says:

    I’m happy Americans can purchase firearmzz such as these. I myself cannot see the benefits of a short barrel on a ryful based cartradge. I’ve always thought the 5.5sixes claim to fame was it’s speed? Hydrostatic shock @ 2000 fps right, without that it’s just a boolit

    1. avatar Baldwin says:

      If you see no benefits to short barrels for rifle cartridges, then you have not done your homework. Purposely giving up barrel length will provide a number of advantages. I have both long and short barrels…different tools for different jobs. Both have earned their place in the toolbox.

  4. avatar Green Mtn. Boy says:

    Luv me some AR pistols,if overall weight is a consideration the Maxim brace while the toughest manufactured is also one of the heaviest on any said pistol.

  5. avatar Gadsden Flag says:

    An AR pistol. Sigh. A bad idea made worse.

    1. avatar Joel IV says:

      Every deer and hog I kill with mine has the same lament. “He really shouldn’t have used a gun that has had 60 years of refinements. He should have used a totally different, perhaps newer, longer firearm in a larger caliber with a different gas system, because then I would be more dead.”
