Anybody try one of these moderators on their sidelever?

Been looking for a moderator for my 48 for a while now. Came across this today.  A bit pricey once all is said and done so please post other options if you know of any in addition to comments on the diana model linked above.

For some reason when I put it in the cart, united states is not a shipping option. Huh. I thought we were past the airgun moderator restrictions. Any other retailers sell this?  Anybody else able to select US shipping for this item?

Krale doesn’t ship moderators to the US.

As I recall, they stopped shipping these items about 3 or 4 years ago.

Knibbs Airgun Spares has no scruples shipping to the US.

Unfortunately, they don't sell the moderator for the Diana sidelevers

Give Buck Rail a look and or a holler: https://buck-rail.com/.  You might find what you are looking for or maybe Terry could whip something up for you.

Please note that those "SchallDämpfer" are for "F in Pentagon" rifles.

Spring-piston airguns are not noisy per se. MOST of the noise the shooter hears is vibrations transmitted through the stock to the skull directly.
Get a padded cheekpiece and you will notice the difference.
For the sidelevers, there is ample space to make "reflex" moderators. No need to screw stuff at the end to make a compact gun too long.

HTH, keep well and shoot straight!

Asked him a few months ago. He had made something for another member once, but didn't have the specs anymore.  Too much work to figure from scratch with so much busy going on right now.

I just removed this from an HW PCP that is getting a proper Reflex one:


It is a proper SchallDampfer:


It is designed for 16 mm's barrels and has no grub screws for fixation.

To fit it to your 48, we would need to either make a pressure bushing that occupied the space between the 16 mm's and the 15 mm's and press it into place, OR
make a more relaxed bushing and drill grub screw holes in the device so as to ensure a good grip (6 holes).

Because the seating depth is much larger (available space is 51 mm's, but the first chamber needs to be reduced from this), vs 12 mm's that the DIANA muzzlepiece seats into, you may need to cut the shim and sleeve, or replace both for a CF fitted sleeve.

So, this would be one solution, but it would cost a lot more than the US$100 of a US landed device from Krale.

If you are interested, let me know.

Thanks for the thought, Hector.  That's more work and cost than I'll put in at this juncture.

Late to the party, but I've mulled those Diana over-the-sleeve moderators over, from time to time. Loudness is the biggest single disadvantage springers have, and a substantial chunk of that is muzzle report, especially on guns with proper guides and lubing.

Contrary to endless claims, moderators do work on springers, from the tests I've done, using 'civilian observation' as well as game animal reactions.

The problem with the Diana (and Weihrauch) over-the-sleeve moderators is that they are long and heavy, which makes a heavy sidelever gun even heavier, a well-balanced sidelever gun barrel heavy, and a compact sidelever gun a long gun.

First I heard that these moderators are F moderators, as well. That's a serious extra issue. Off the cuff, I'd assume an F moderator would have the same shell but lesser internals than a moderator for full power guns, and could be modded for higher specs.

The reflex moderators Hector brought up seem like a really good solution, if the home manufacturing can be realized, hundreds of dollars of total costs not being seriously considered for a gun that cost about the same or less.

Thanks for your thoughts, Duke. I wish there were some sort of adapter for the front sight of the sidelever that would allow for a standard threaded airgun moderator to be usable.

[Struckat]

Are you trying to keep the front sight and add a mod? If not take the front sight off and put on an adapter and screw on your mod?
What am I missing?

I just bought an adapter and mod from Airgun Capital. His new metal mod is very well made and works well.

Ok, I see in one of your other posts that you want to use the front with a mod.

Does the front sight just push on to the end of the barrel? If so, remove it and drill it out the front so it is the same size. You should be able to push it back further on the barrel which would allow an adapter in front of the sight.

I did this with another brand and it worked well.

Curious about your observations, Duke.

I have measured the SPL of springers under the proper scientific procedures (perpendicular to the muzzle, at the same height, and then varying distances), and for the most part, at least when using reasonable power levels and not exceeding the sound barrier, beyond 18 m / 20 yds, the SPL goes below the 70 peak dB's in the "C" scale (that is the SPL of a normal conversation between humans).
At closer distances, it CAN be higher, especially in 0.177".

So, as far as humans (neighbors) are concerned, it is my experience that anyone beyond the 20 yards line, will not even care. A nailing gun/power stapler will make more noise.

Animals have super sharp senses and, sometimes tuned to things we do not think about, like deer to the "hum" of a bowstring as it is pushing the arrow and thereby anticipating even the release of said arrow. Personally, I have never experienced any animal reacting to the "sound" of a pellet shot from a spring-piston rifle (others have relayed me differently, more on that later). For ME, they do react when they feel/hear the pellet "zing" by too closely, but for the most part they just stay there wondering what is happening . . . till the next pellet finds its mark, LOL!

Reflex silencers are better than muzzle screwed ones because they are not cantilevered, so any "bump" in the field does nothing, while devices that are attached ONLY at the muzzle, are sensitive to mishaps.

Just recently, a good friend was suffering because his Daystate Huntsman was not shooting well at all after a small drop from the shooting position onto the bench. We were shooting side by side on the practice range and when he asked I suggested he remove the front cap of the LDC.
¡BINGO! groups were back to their customary precision again.
The LDC had moved and the front cap was "clipping".

Yes, well built things cost money, that's the way of the World.



The top is a "k" version of the AM03 with a muzzle mounted LDC
The middle is the same model rifle without the muzzle piece.
The Bottom is, again, the same model with a reflex.

Shorter, quieter, and sweeter.

Was it really needed? Didn't initially think so, and I tried to dissuade the customer he, however, wanted it...

Later feedback clarified why:

He shot at bait stations. So, for the "sound" that travels ALONG the bore's axis, there seems to be a definite usefulness.

Those are my experiences and that is why I am interested in hearing yours.

THANKS!
