Just curious if the above would be effective. I have a Sparrow suppressor and yes it is legal. Wondering if I could use it on a air rifle. Since legally suppressors are registered and not gun specific I was wondering if it would be effective at suppressing an air rifle's noise. I know the suppressor is a 1/2x28 thread and most air rifles are 1/2x 20 but there are adapters.
Just wondering if anyone here still dabbles in firearms still and might know. I have tried to search but have found little on the subject.
I am a powder burner myself. Yes it will work, but they function a little differently and you will get a lesser amount of reduction. Here is why. A good suppressor functions to take the heat from the initial explosion and diminish it outwards inside the suppressor, usually by way of first a metal mesh that retains the heat and then the Hot air goes into the baffles.
An airgun suppressor, however, functions not by removing heat but by dampening the fast air right behind the pellet. It does this by sometimes using acoustic materials like sheets and foam, but primarily by chambering the air. This is why you can have unconventional shapes and size moderators and still have them be very quiet, as the best moderators usually have larger chambers Sound reducing chambers (Sometimes in opposing direction of the projectile).
hope that helps.
