I will be in Germany next Summer.
If you can wait till then, I can put a shipment together. 👍🏼

*Whoa!* Thanks for the kind offer Matthias, will touch base with you just before then, if we don't find a way sooner.

thanks again

[JungleShooter]

Hey, I just searched online for an HW unit and found Wolf Airguns in Poland(?) and they ship to the U.S.

Seemingly cheap prices as well... and only $9 shipping (per unit).

So I ordered TWO (2) Weihrauchs - a standard model (210mm x 30mm) and their "High Efficiency" version which is just a bit thicker (210mm x 35mm)

The total came to $126 ... for BOTH Weihrauchs including shipping.

Will let y'all know how it goes when they arrive...(they say shipped in 5-10 days)...

Links if anyone wants to check them out, they have all KINDS of LDCs, not just Weihrauchs:

Dang, those suckers are 8" long!  I bet they work though.

Yeah Donny that's so's if ya miss you can still beat'em to death!

That's the norm in Europe, most units are 30mm diameter and 200mm long. Marksman is 38mm x 225mm and that one is really quiet.

I can imagine how much More quiet they must be on 12 FPE guns. You guys are lucky to be so spoilt for choice...

There was a question about what the different LDCs weigh since that may become a factor in POI shift if heavier, so I thought I'd better go weigh mine.

In order of lightest to heaviest weight:

GEO (ebay)      = 1.7oz

Diana (factory) = 2.8oz

Rocker1           = 3.3oz

ZERO db          = 3.5oz

Tanto              = 3.8oz

Sumo              = 5.7oz

Huma 40mm    = 7.6oz


It should be noted that:

the 40mm Huma comes in a 30mm diameter as well, plus its several sections can be screwed on and off to suit the airgun application at hand.

the Rocker1 is available in different custom made sizes and formats

the ZERO db I have is their shorter length model (110) while a longer (160) version is available.

Donny that's what She said last night (and then I woke up, dang it)

It may be a good idea to include the length and diameter of the LDCs along with the weight for better context.  The Huma is a bit of an odd ball in those respects too, because you remove sections and even remove the damping material from sections too.  I currently have the damping material removed from the first section of mine to allow for a bit more air expansion.  I really couldn't tell much difference between the sound with the material removed on the first section, but I've been too lazy to put it back in there to retest,lol. 

I will say I experimented with the materials on the Sumo when I had it.  I had some foam I used to tame it a little bit, but I never could get it to be as good as the NC or Huma.  I would love to try out one of the STO LDCs, but I wouldn't even know how to get one.  I sent them a message about a week ago, but have gotten no response...

Wow, some of those are pretty light. For comparison, the total weight of the "fuel filter" type I happen to have hanging around is 16.4 oz! But that thing is huge too: 2" diameter and 10" long. The weight the breakdown is as follows:

• 5.9 oz total for the end caps and spring. These are heavy chunkers.
• 7.6 oz for the cylinder (no end caps or filter)
• 2.9 oz for the filter alone. It really is a paper filter cartridge, so that will have to go sometime in favor of something more appropriate.

  would you bet that the mass helps absorb sound, though?

and Donny, what is STO? 

[Rallyshark]

STO = Silent Thunder Ordinance.

[scion19801]

A good filler material that I found was weather stripping felt for doors and windows.

[Long_Gun_Dallas]

I have both 30 and 40 mm humas.  The 40 is substantially heavier.  While the 30 is still extremely effective.

The most balanced config for effectiveness/length/weight on the 30mm moderator is 3 40mm long modules and 1 20mm.  6.4" and 4 oz on the dot.  When hunting I only use 2 modules for 2.8oz, and 3.9" length.

Thanks for the STO info Dallas and Donny.

Dan, is that insulation like a dense foam rubber, and some come with a peel-and-stick side?

[scion19801]

No adhesive at all I guess it's more for doors than windows. But looks like this. Comes in different width I believe. I also used stainless steel screen with small gap pattern to keep it held to inside of can and to help it from being blown out the end.

Cool, thanks Dan. Might be something to consider once I start blowing out all the stuffing in mine...
