Foam filled "suppressors" do reduce the sound. The air that comes out makes a noise and masking that helps a bit. If you fire your empty gun with and without holding your finger over the barrel, i'm sure you'll be able to tell.

oil filter is supposed to work on actual firearms

so on that basis if anything is REALLY going to work

it will be one of those bastards

(google oil filter suppressor)

most suppressors just change or slightly dampen the sound

they are like farts, some are more quiet than others

and love is like a fart...

if you try to force it too much - it will probably be shit

you could a piston brake or silicone pad over sorbo can lower the piston slap...

 often wondered about all those baffles/padding etc...

but it must work of a sort coz going the other way...

Don't buy a daft sound hog or FireHawk tip to become a loud annoying player on the field...

Just cover/tape up a M4/M16 flash hider to make a massive CRACK for no costs at all

So in theory going the other way some sort of "venting" or "slots" as well as the dampening material inside should perhaps dissipate the dulled sound ???

NB: this is just a theory based upon the M4 CRACK you get if you cover the flash hider

(try it - really makes a loud crack)

So if an enclosed hider amplifies then maybe - just maybe a vented sponge might just might be a little more effective too perhaps

Dunno - but I did wonder about all this crap coz most of it just changes the sound of the air, yet most of us still have grindy AEG's making the most sound

The padding deffo does "something" though

if you unscrew one them cw/ccw suppressors, pull out the spring/padding

it makes a friggin' amplified CRACK too...

just wondered if a cheapo slotted or swiss cheesed one would maybe be more effective ???

ignore almost all of this coz I'm just talking crap coz I'm bored atm

You want to dampen the sound?

Unless you have an airbrake I suggest to glue/pressure fit a rubber door stop onto the cylinder head, so that it dampens the impact of the piston head. An alternative would be to use a big fat o-ring in place of the door stop.

Did it on my Striker and it killed the sound so much I can easily run without a suppressor and still be quiet as hell.

On a suppressor there are a few things you can do.

Scotchbrite disks in place of foam and plastic/rubber baffles.

A fart flap helps a lot in lowering the sound but it needs to be done right otherwise it'll just throw your shots way off.

Also, something that most 'softers don't care about is a correct volume ratio for the bb weight.
