Modular Airgun Silencer or Moderator, MOD40-4/0 pre-assembled with 4x40 mm. modules (Standard)


This silencer, or moderator, consists of a start chamber with fixed female treads (available in several sizes) three extra 40 mm long volume chambers and an endcap.
All these four 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.

This is probably the best moderator available on the market.
I have my American Air Arms Evol 30 HP unbelievable quiet now.

Best mod/LDC/silencer on the market today. I’ve had them all and this is well made, adjustable in length and quietest of them all. Excellent customer service and fast shipping.

Now that spring has finally arrived there has been ample opportunity to use my M40 Moderator.
I find using 2 sections it out performs the original moderator on the Huntsman Regal XL 25 caliber; making the rifle near whisper quiet.
With 4sections in use the outrageously loud Seneca Sumatra,25 caliber, long rifle no longer requires hearing protection, and is almost urban back yard friendly. (On high power)
I have found no impact on the accuracy of either rifle.
Fit & finish are excellent, and the design is very well executed.

This is my second HUMA moderator”
I have a FX Crown in 22 cal, works great & looks good on the rifle! Just bought the 25 barrel kit and hope to get the same success!
HUMA & FX can’t be beat”””

I have to give it up to HUMA again for making an outstanding ldc that not only works, but looks good. The functionality and finish make this an overall top choice. This is my second unit and I will buy more in various calibers. Sound quality from this ldc is incredibly good. Very quiet. I highly recommend this Modular Moderator. Thank you Huma!
