most quiet moderator in real life test ????

I've got a alu moderater that I use on my sumatra.25 cal and it's pretty quiet even on full power which is close to 100 fpe. I bought one from buckrail that is printed. On my .22 cal liberty pushing 52 fpe it's the quietest moderator I heard. You hear the rifles mechanical noise more than the discharge. It does hiss a bit. lol

Previously had a Huma - they are a darn good LDC no doubt but for me, the lower .db of the STO Accipiter in a rig that weighs a feather - 80% less than the Huma - that combination wins every time.

I don't think anything can compare to the basic aluminum can that came on FX guns and add 3d printed baffles with a very tight bore.
With 2 75mm center sections and 7 baffles it made my 132fpe .30 impact sound like one of those silencers you see on TV except quieter. You'd still hear air coming out for a second after the shot. I sold my DFL Ronin within 30 minutes of the first try because the difference was night and day.
I don't sell these anymore but I'll show the pic as an example.
I redesigned the baffles with a steeper cone so that more baffles can be used, reduced turbulence and to delay the air longer.
It's better, faster and stronger to print these in PETG with a 1mm nozzle in vase mode for a single wall.

Nice results! I surprised that 1mm wall thickness can hold up to 132 fpe. Which cones are closer to the muzzle, the steep angle or shallow ones. I wonder would using all steep angle baffles be even better? What is your center hole diameter for those .30 pellets?

I use all of one or the other. The red one is the new design I made and is 38mm diameter for a different aplication. I run the center hole very tight on my own guns and only shot slugs.

^ I use basically the same setup that I originally got baffles from heavy-impact a long time ago for. Or what seems like a long time... time is sort of relative, I suppose. I've since broken some baffles and printed some myself, but it is the quietest design I have used, and I have some of the old huma mods that were the quietest off the shelf mods at the time. I believe they still are. But new ones are a different spec now, and not as quiet.

I've seen using water (sprayed into the moderator) for PB, but never for airguns. And yes, for PB at least, it does make a difference for a few shots. Not sure how effective it would be for airguns or what effect it would have on accuracy. No moderator will stop the crack of supersonic/transonic rounds.

If you know someone to print them you can use my files I only have .25 cal on there but you could use them for .22 as well.

I'm sure there are online services that will print for you.

This is awesome. I would love more in-depth info in messages if you are willing or heck even text or chat?

Almost all of mine are inexpensive printed mods. For me indoors it’s a drastic difference, pcp or springer.
I absolutely could not shoot in the backyard without one.
I was bummed when Airgun Universe shut down. GEO made very effective mods. The thread on quiets my AA500 22 very well at full power.

I made them for you. You only need .177A for a single center section. Use A and B for two center sections. https://www.thingiverse.com/heavy_impact/designs

You may just get me to buy a 3D printer... LOL!
Oops, I see them now... (smile)
Thanks!

For me, the quieter the better for many reasons. Fortunately, the Fortitude and the DAR (both in .177) are/were (respectively) quiet enough for my purposes without adding a moderator/silencer.
In any case, thanks for the lengthy explanation of why water works with PB moderators on an airgun forum... (chuckle)
Sorry, couldn't help myself... (smile)

Airgun moderator function is simple. Disrupt disperse, and delay flow of chairge air (baffles and volume accomplish this). Dispersing and delaying pressure release. The better these 2 are accomplished the better the result. Sound dampening material like felt can also be used to absorb some of the sound waves addtionally. As stated, this can also be aided by tuning the gun to utilize a smaller, higher pressure charge. Reason being that charge volume is going to be less, which means it is easier to disperse. Often this actually occurs inside the barrel before the mod even begins to do it's job.
