Damage Industries AK Muzzle Brake and Projector Sleeve

All the muzzle brake blast shield/diverters we’ve posted previously were for the AR15, here’s one for the AK47 shooters out there. Damage Industries has a version of their Four Slot Vent AK47 muzzle brake with outer threads for use with their Projector Sleeve. Just like with the other diverters on the market theirs directs the muzzle blast and concussion forward and away from the shooter and others along the firing line. Their Four Slot Vent Brake retails for $34.95 and the Projector Sleeve retails for $34.95 as well.

    Doesn’t this entirely defeat the whole point of using a muzzle brake?
    (that being to use the escaping gasses to counteract the recoil)

    • Budogunner

      I agree. I don’t see the benefit over a target crown.

      The only possible reason I can think of four manufactures to do this is to set up QD silencer mounts. Many silencer owners choose break mounts over flashider mounts because the break itself can serve as a sacrificial, replaceable baffle.

      If these companies don’t offer a matching suppressor, I’m at a loss.

      • BattleshipGrey

        That is the purpose of brakes, however IIRC, the idea of the sleeve is so that if you’re shooting in confined spaces or near other people the gasses are forced forward instead of to the sides. It allows you to choose which direction you want the gasses to go based on where you’re at and what you’re doing.

        • TechnoTriticale

          So this allows you to “switch off” your brake without having to remove it.

          I suppose there’s some modest market for something like that.

          • ostiariusalpha

            It still does some recoil mitigation since the brake diverts the blast into the cup. What comes out of the cup is diffused in energy and direction.

          • Squirreltakular

            Bingo. If I was running shoothouses often and suppressing wasn’t an option, I’d definitely want one.

      • John Yossarian

        I’m certain that these shrouded brakes and blast directors (like the Krinkov or Bulgarian 4-piece) do more to send the blast downrange than just a bare muzzle. But I would still put a target crown on the muzzle before adding the brake, just because I like over-engineering so much 😉

    • kyphe

      Not really no, most brakes do not actually divert gas to the rear which is needed to offer a counter force, instead most simply divert a decent volume of the gasses that would normally go forward and add to the recoil pulse. the sleeve does reduce this effect but the diffused gas pressure is still less than it would be.

    • Ben

      It largely does negate the effect of the brake. However, it allows for more polite shooting experience at a range, where you have other shooters next to you. When you are taking a class or on private property, blast away with that brake concussion.

  • Edward M

    The cool part about AK’s is its so easy to index different muzzle devices. Just make a linear comp in 14×1 like they do for the PAP. That looks heavy. Cool idea….in theory….more practical on AR’s.

  • BattleshipGrey

    Can’t believe its reasonably priced. All the ones for ARs are $100+.

    • sam

      Yeah, my first thought was “woah, reasonably priced”.

      I like the lines/cuts/material too. I mean, hard to say what’s better or worse since I’ve never used one, but it looks like serious business.

  • Sam Schifo

    I hope they make one for AR-15s at the same price point.

  • gunsandrockets

    I would think that firearm blast diverters would have a tendency to increase rearward thrust from exhausting muzzle gasses, just as the bell nozzle of a rocket engine contributes to an increased thrust from the exhaust plume.

    Still worth it.

    • Paul Epstein

      I don’t think a rocket engine is a good comparison to make. The gases are first deflected sideways, and then expand through the space between the brake and the diverter until they hit the walls, and only then do they start leaving through the front of the device. So you have the combined effects of the energy that’s dissipated by hitting the baffles and diverter wall, the decrease in velocity compared to the gas leaving directly from the muzzle, and the delay in it’s recoil compared to the recoil of the bullet and the gases escaping directly behind it.

      I can’t say with any confidence that those would decrease recoil, but I certainly can’t imagine they’d increase it compared to a bare muzzle.

      • Bruce

        The real bonus here is in the field vs firing line use. Put the diverter on to make you friendlier to others on the firing line, enjoy reduced recoil when shooting by yourself or on the field course.

  • gunsandrockets

    Bit off topic, but…

    I’m not up to speed with the current marketplace of available AK brakes. Does anyone import actual AK-74 brakes or make an accurate copy? The AK-74 brake I know of disassembles and has a chrome lined interior expansion chamber.

  • ASterisk

    I’d really like to see this set made for the m92 PAP threads

  • All the Raindrops

    What is the exterior thread pitch?

    Crap or Lies…you choose.
