Modular Airgun Silencer or Moderator, MOD40-3/1 pre-assembled with 3x40 mm. and 1 x 20 mm. modules (Compact+)

This Mod40 moderator on sale has a slightly less finer structure than our normal moderators due to a different method of sandblasting. 
As we prefer the finer structure on our moderators this batch will be sold with an extra discount.
Also these moderators have a fraction smaller bore as the current production.
All parts are new and unused and have normal warrenty.

This silencer, or moderator, consists of a start chamber with fixed female 1/2UNFx20, or M20x1 treads (used on several FX models) three extra 40 mm long volume chambers, one 20 mm volume chamber and an endcap.
All these four 40 mm chambers are filled with wired metal inserts wrapped with our special Kevlar ® enforced ballistic fibers to minimize the sound.
This system allows you to configure your own silencer in term of lenght, caliber, volume chamber size and content of the internal silencer chambers.

Optionally you can add or remove volume chambers with different length, volume and internals.
By mixing these variables you can influence the frequency and output decibels of your silencer and adjust them perfectly matching your rifle.

The benefits of the Huma-Air Modulair Airgun Silencer:


  • The possibility to make the silencer rifle specific, will allow you to reduce the output noice 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.

I got this for my Crown Continuum because the moderator that came with it is just an empty can! This thing is amazing! I own several different brands of moderators and this one is the only one that allows you to configure it for your power needs. It's super quiet and the build quality is exceptional. I would definitely recommend it to friends, in fact, I already have!
