Witt Machine Directional Muzzle Brake

Witt machine has a new combination muzzle device hitting the market. It is a three piece unit that includes a side vented comp that is threaded on the outside (as well as the internal threading to mate to your rifle).

They are CNC machined from 416 Stainless Bar Stock and come in three finishes (Smooth Stainless, Graphite Black, and Desert Sand).

You can fire as is, or thread on one of two additional shrouds. There is both a spiral cut flash hider and a noise and sound directional sleeve.

I was able to briefly test fire all devices at the booth here at Range Day, and I am pretty impressed. The directional shroud did a did a really good job of reducing the perceived sound, and all combinations of the device did a great job of not annoying the shooters in line behind me (nor was it annoying to me to be in line). There was not really a way to assess the flash suppression, but I didn’t notice a huge fireball either… 🙂

It ships with the base piece, a spiral cut shroud, the solid directional shroud and a new crush washer. It is threaded 1/2-28 and bored for .223/5.56. Overall length is 1.75″ and .950″ in diameter (at the widest with a shroud installed). MSRP is $125.

They also are producing a large caliber version threaded 5/8-24 and bored for caliber of choice. Same price but the overall length is 2.25″ and .995″ wide.

Hopefully I will be getting one in to do a full T&E on…

    I think he meant perceived noise to the shooter since it is directing it forward.

    • Doc Rader

      Yep, I did state perceived sound. I’m sure if we put a decibel meter forward of it we’d register the same level

  • Dan

    What exactly is purpose for the spiral cut shroud? Is it merely for looks or does it dissipate sound?

    • Doc Rader

      I believe that is the flash suppression shroud. It was much too bright and the guns were being shot too heavily to test. If I get one in for T&E I’ll try it at dusk.

    Nailed it!

  • gunslinger

    how is the “directional sleeve” not a suppressor? seriously, what is the testing method to determine the noise reduction and classification for the ATF?

    • Doc Rader

      It directs the energy forward. There are no baffles to entrap the gases. And it only reduces perceived sound as far as I can tell.

  • Doc Rader

    They had rifles set up in each configuration. Firing each in sequence there was a noticeable difference. The directional did a great job of not pushing crap back or to the sides and so was not distracting.

    The also had rifles with A2 installed and there was a noticeable difference in muzzle rise.

  • Doc Rader

    Derp. My bad.

    a solvent trap, obviously!
