Huma-Air Mod30-1/2 Moderator test 2, muzzle dB

[Montana_Airgun]

This review and testing video of Huma-Air Mod30-1/2 moderator for a second time. I conducted the test video with a HatsanFlash .22 PCP that was used on my previous test video. Now the dB measurement devise is one letter paper away from the muzzle.

DB readings were as follows:
Control group:
82,4db
82,1db
82,1db
80,2db
82,1db
avg = 81,78db

Huma-Air Mod30-1/2:
80,6db
80,5db
80,7db
80,6db
80,5db
avg = 80,58db

Can you try it without the felt or plastic extra baffle inside the different sections. Curious if the added volume helps. I pulled the felt from mine and it seems to work well, I just don't have a sensor to measure.

What I found out is that its more guiet with the felt in. Its also sounding nicer to have the felt inside.

I usually test them in my basement and coudn't really tell a difference. Thanks for giving it a try and reporting back.

If you get one of the new Mod30s with the Avalanche inserts, you can take them out and use hair curlers with felt wrapped around.

I must have 5 Mod30s and 3 Mod 40s. On a higher power rifle, sometimes I leave the first section empty or with an Avalanche in it. That allows for greater expansion than if that section is filled with felt. The rest of the sections can be felt - has worked great for me on .25s and .30s.

I believe that Huma will even sell you the old “curlers” and felt inserts if you request it from them.
