ALG Defense Sidewinder 5.56 Muzzle Brake

sidewinder-angled-ss_2

ALG Defense recently released their Sidewinder 5.56 Muzzle Brake. It features vents angled upward towards the 3 o’clock and 9 o’clock positions to deflect gas to the sides, the vents are also larger at the top than the bottom to help reduce muzzle rise. The most interesting feature of the Sidewinder are the two angled canards in front of the vents that ALG claims makes the Sidewinder even more efficient at reducing recoil. The Sidewinder 5.56 Muzzle Brake comes in both a bright polished and black nitride finish and retails for $75 over at ALGdefense.com.

ALG Defense’ new Sidewinder muzzle brake is machined from 17-4 Stainless Steel and fits ½-28” threaded 5.56mm barrels. Vents angled upward at 3 and 9 o’clock deflect gas to the sides, away from the ground, reducing dust and debris signature when firing from the prone position. The vents also are larger on top than on the bottom which adds muzzle rise compensation to the ALG Sidewinder. Twin angled canards in front of the vents boost the recoil dampening effects of the Sidewinder by increasing the forward surface area while still keeping the slim, minimalistic profile of the ALG Sidewinder.
The ALG Sidewinder includes a peel washer for proper timing and concentricity during installation.
The ALG Sidewinder’s unique design reduces muzzle rise and recoil, allowing the shooter to quickly get back on target for rapid follow up shots. Available in both Bright Polished or Black Nitride finish, Sidewinder is form inspired by function, a unique addition to your weapon system.

    This appears similar, but not identical, to a muzzle brake that I designed (Inspired by the AK-74 brake of course) to make on a manual lathe and milling machine half a decade ago.

    I posted the print on a home gunsmith website, I’m sure this is more of a case of form follows function than anything else.

    If anyone is interested here is the print. I am not an engineer so this is obviously for entertainment purposes only.

      It’s in imperial and definitely not GD&T, so no worry about being confused for an engineer 😉

      Did you try it out to see how it worked?

    The muzzle brake seems cast so not much machining

  • BattleshipGrey

    The uncoated version looks like something that just fell off of an old fire truck. The black version looks nice though.

  • sianmink

    The polished version looks just like some kind of OSHA airblaster safety nozzle.
    I’m sure it would be great if you’re making an ‘industrial’ style AR build, but I’m not sure otherwise.

      I watched a video made by the designer before the shoot and he said the stainless steel one, after shooting and getting hot, will tien into a cool bluish color like a jet nozzle. Also it looks very small, while still having a lot of surface for the gas especially to push on.
      I like it.

  • JumpIf NotZero

    Fwiw, smaller than I thought it would be in person. Quite tiny actually.

    This cast muzzle-brake with little machining should be very economical to produce. I wonder why their business strategy was to market it at the medium-high end of the muzzle brake price spectrum?

  • BryanS

    $75 for a cast AK74 brake?

    ?

    Gieselle starting to bring new designs again after a year or so of stagnation without a head engineer. Good, it looks like it should be effective but probably obnoxious sounding like all breaks.

  • dan citizen

    I like it, especially in black

  • William M Durham

    Great but why no price? It would be nice to at least know what it cost an who sells it.

    The canard flaps are to increase the surface area for the forward flowing gasses. Although I make no claim to be a expert, not to a warrant the accuracy of my post but I believe the idea is that as the forward flowing gasses hit the canards they push forward on the break directly counteracting recoil aside from the usual “vent and redirect” function of a muzzle brake

    Looks like the OPS Inc. Brake/compensator to me; not much really new other than slight design variation.
