Best / quietest mod for an fx impact m4 .22?

[DMoney]

Looking for a moderator for a new .22.
I bought a cheap buck rail for $50 delivered and it has a distinct ping at every shot.
So... give me your advice please.
I know bigger is quieter but, how big do I need to go?
Shooting 34-40 gr slugs at max setting on a stock gun.

I use a Donny Tatsu on my .22 compact and it is very quiet. At your power level, you may need a Shogun sized mod?
I am running FX Hybrids at 925 to 930ish for comparison.

HUMA moderators have worked the best in most of the airguns I use,.otherwise go for an STO moderator. The website name is Silent Thunder Ordinance

I have found the one that came with mine to be very quiet, I'm actually quite impressed with as quiet as it is considering it's just an empty can!

Utah airguns sells a baffle kit for the Impact "can" made by Impulse Air, called The Fix.
Works well in mine, used on a .22 M3 700mm .
$89.00

If your gun is tuned properly, it doesn’t take much to keep it quiet. None of my three FX slug guns wear a mod longer than 4”.

Do your airguns have active shrouds? That should make a difference.

Just the standard shroud with the air stripper. No additional components in the shroud to enhance sound control.

Thanks Vetmex,

Distinct from direct barrel attachment, is really the point I wanted to make. In the latter case a 4" long mod is unlikely to be enough, unless the goal is just hearing safe.

But your point about good tuning being important is rock solid.
