    While it seems sensible on paper, is it difficult to align the grooves at the muzzle with those on the flash hider?

    Even with a given twist rate, different length barrels would have their grooves oriented differently at the muzzle. I presume there’s a required torque needed, etc.

      It looks like he’s angling the slots in the flash hider the same as the lands and grooves in the barrel. Flash hiders typically don’t have lands and grooves, they let the bullet fly free. So the slots have no need to be aligned with the rifling in the barrel.

    I dunno, Man. I’m sure they are very effective suppressors and they look great, but matching the twist rate? Sounds a bit hocus pocusy to me.

    Sean; Aligning the groove? That’s too much to take seriously, but I suppose someone will try it. Wearing a rabbit’s foot in one’s pocket will probably work as well.

    Sounds like a major load of garbage as anything other than a novelty.

    So, what’s the supposed benefit to having a twisty slot aligned (more or less) with the rifling rather than a straight slot aligned with the barrel bore? Does it affect external ballistics? Does it affect how well it minimizes muzzle flash?

    Or does it simply effect sales?

      I am thinking based purely on my scientific education thus far that your last statement is closer to the truth than the manufacturer would have us believe.

    They do look cool, and if they hide flash really well then I’m good with them, marketing methods notwithstanding.

    Interesting that it says “patented” but doesn’t list a patent number. That’s weird because you get no benefit unless the number is listed (and is indeed the number of a valid patent actually practiced by the product). Yet more evidence of the “it’s just looks” theory.

      Is there somewhere that the manufacturer states that it’s NOT just for looks? That it was just for looks was pretty much my immediate thought. Followed shortly by “WANT!” Which is somewhat odd because normally I don’t give a damn about flash suppressors…

      PS to Oleg: What’s with the Save the Rainforest captcha thingy? I didn’t take you for an environmentalist…
