Huma Mod 40 Standard

The benefits of the Huma-Air Modular Airgun Silencer:

  • The possibility to make the silencer rifle specific, will allow you to reduce the output noise to an absolute minimum.
  • The precision machined volume chambers are screwed into each other making it very easy to switch or change the setup.
  • You can ad or remove 40 mm or 20 mm long volume chambers to the setup.
  • The internal parts of the 40 mm chambers consist of a metal wired sleeve with Kevlar (aramid) enforced ballistic fibers around it to reduce the sound.
  • You can also choose to use maximum volume, without the standard inserts in the volume chambers.
  • The system is caliber specific in a combined .177 /.22 version, a .25 and a .30 model. Of course you can use a .25 model also for .22 and .177 too.
