Yet Another Torture Test: This Time AR-15 Pistol

Capture

BigDaddyHoffman1911 is the latest YouTube channel to hop on the “torture” test band-wagon, albiet this time I would consider it a legitimate test of a product. BigDaddy and his clan put the KAK Flash Can, an aluminum blast-forward muzzle device through a heavy battery of fire to see if its aluminum construction can handle some hot 5.56 loadings. 300 rounds later, the gas tube is red-hot and the KAK is in good shape.

Hit the video below to see the extent of how the aluminum device held up to the 300 round duty-cycle. While not a definitive or exhaustive test, I personally would have no issue putting it on the front of one of my rifles. The lower weight is even better!

    Haters going to hate… Wonder how many holes are in the roof of the shed behind the left side of their backstop… pretty impressive for 300 rounds

  • Rob

    So, explain blast forward devices to me…wouldn’t redirecting the gases forward just counteract any compensator you have on the muzzle?

    • Anonymoose

      I’ve wondered that myself, but because it is first redirected to the sides I think the recoil forces are dispersed before blowing forward with the flash/bang.

        There doesn’t seem to be enough room in the device for gas to go sideways or to the rear enough to matter. It’s not a great comparison, but in playing with an older .50 BMG precision rifle the muzzle blast from the brake is noticeable yards to the side and rear. It would drive spotters nuts trying to find exactly the right spot to be in to avoid it and/or send range cards flying. Granted, a 5.56 isn’t going to be that severe.

        • iksnilol

          .50 BMG and 5.56 have similar max pressure(!)

          I still think the blast of 5.56 from a short barrel with a muzzle brake is going to be severe.

  • Bill

    It looks like a direct copy of another company’s device. The original was way too pricey for me.

    This was “interesting,” but without seeing how well it suppresses flash at night, and/or some decibel readings from the front, rear and back to compare against a stock hider or comp it only tells me that it will hold up to sustained fire, which doesn’t mean much in the civilian world.

    • Greg Johnson

      The “other company’s device” produces back pressure to aid in cycling poorly gassed shortys. My rifle is gassed properly so the KX5 caused issues.

      On the line, the flash can is definitely more pleasant to stand next to than an a2.

  • BrandonAKsALot

    Sooooo what was the weight after it was cleaned? Obviously there was build up on the device, so weighing it after cleaning would give you an actual result.

    • thedonn007

      I was thinking the exact same thing. So, clean it and then weight it. Also, I would have been nice to actaully see the KAK flash can on the scale before they started using it.

  • Don Ward

    The new terminology is “Enhanced Interrogation Test”.

    Thank you.

  • thedonn007

    The ammo they blasted through that thing cost more then the KAK Flash Can.

    • Don

      Not for the guy running the test, he got the ammo for free he said.

  • DataMatters

    Turning ammo into Youtube views. I wonder if the fools who make these videos ever break even. Honestly, what is the point except redneck street cred? There is nothing remotely scientific about any of these torture tests. Everyone knows an AR type rifle will break if you shoot it a lot without letting it cool off. Not…rocket…science.

    • Don

      He said that Blacked Out Arms supplied the ammo for their test. Most of the guys who make these videos who have high viewer counts are given the products to test and most of them also get the ammo for free as well. So they get the best of both worlds, they get free ammo and they get to try some cool new toys. The same thing goes for the guys / gals that test bike equipment, camping equipment etc… Some times they are given the products after their tests are complete and their videos are uploaded and some time they have to return the products.

  • Rob

    Hmm…so it’s a muzzle device of an entirely different vein than I’ve heard of before. At first I was think it might be like the AKSU can, but that’s for an entirely different purpose. Ugh so many things in the gun world .-.

    • Ben

      Well in terms of primary design intent (to ensure reliable operation of an SBR by capturing gas at the muzzle) they aren’t that different, and use the same design elements (a cone and a tube) just structured differently. The muzzle device on the Vietnam era carbines has the same purpose and broadly same design as AKSU flash-hider.

      The cone flash hider design is one of the earliest I know of. The earliest rifle I know of using it in service is the SMLE #5 Jungle Carbine.The KX3 (which was patented 20 years ago co-incidentally) just uses a wider cone to manage the gases differently.
