Donnyfl Fat Boy 2. What are they doing?

You know. This is one of those YouTube vids that made bought the Fatboy that I'm currently, desperate to look for a real moderator to replace it with.

Speaking for the replacement, it seems that the STO is a candidate. Anyone with other recommendations?

Thanks.
You know it's funny, to me, how vendor bashing being allowed on this forum seems to be specific to the vendor, but that's a different problem.

You want somebody to recommend something different you have to tell them what rifle you're putting it on how much power that rifle puts out you and how much moderation you want.

Like I said in my first post in this thread, almost any moderator is a good moderator on the right rifle. That should tell you a moderator is application specific and picking the right one is a hard job.

I can clearly hear what I would deem to be a 3dB improvement in his video at the 20-yard Mark directly in front of the rifle. Over my 70 years these ears have seen a lot of really hard use.

That means that I have evidence from his video of one of two things, either he lied and faked that video 🙄 or that moderator is a real moderator and it does work on his rifle tuned the way it's tuned.☺️

I have no doubt that STO is a fine moderator. It's a very beautiful moderator and any moderator that's twice as big as the next should be about twice as good and should work very well. When you are comparing moderators you need to compare apples to apples.

When you pay twice for one it should work twice as good. Unfortunately what I have seen in the moderator business from my limited experience is that price performance ratio decreases with the square of the performance... 🤔

If it's twice as big and it costs twice as much... You should probably see an improvement.

Hello,

Didn't mean to vendor-bashed or to offend anyone. But I see what you mean. He could have a good tune on the gun for the specific silencer. It's something that I have to work on.

Sorry if you're offended.

I’ll only buy STO from now on but the Huma mod 40 seems to actually work too.

I will add to what oldspook was eluding to. I am not or have ever been impressed with DFL mods when comparing them to others. But….on two of my guns, they can’t be beat. They are what those guns like. But generally all mods that don’t resemble a roll of toilet paper painted black work well. I’ve never had a Huma, Huggett, Weihrauch, or even a good one made by known members here that have standard dimensions disappoint me.

The best I have found thus far are the Huma Air moderators, but I see they have changed their design as well, so I have no idea if their new design is as good or better than their last one. I had the original Fat Bay and was quite disappointed also. My Tanto and Koi were quieter! When it comes to moderators, I really don't believe bigger is better, I think it has a lot more to do with the design and implementation of the baffles.
Agreed.
My favorite is the original Huma (30,,, and 40mm, never tried the 50mm) that's "Kevlar" wrapped. The new "Avalanche", with plastic baffles produce a louder, sharper note.
Also...yeah, my "FatBoy" has just been sitting ! I keep trying in on different guns, with little luck. Seems the lower power that coming out of the barrel, the better it works.
And NO...YouTube has nothing to do with how well it may work...OR not. Even the guys at Donny told me that I have to buy a second section, and the stripper ??? WTH.
Spend more, good money after bad, and still end up with just a barrel weight, NOT...gonna happen ! The DonnyFL boys made out on this one.

My second best to the original Huma is the 0dB muffler. It seems to work well no matter the guns power.
A close second/third is by "Bullysyclone". A poster on this board. He builds a muffler that works well, AND, looks good too. I have a couple.
A couple other people (oldspook for one) make 3D mufflers that work well, but are in third or...place. At least the ones that I've tried.
Then, following up are the baffled "brand named" styles, that...well, sorta work, but, could work better.

And sorry, I don't buy using the...superior $20 meters from Amazon to tell me what dB a gun is producing. After having spent 20 years in the Aerospace Industry, I've seen "very clearly" the difference in worthless hand meters vs testing in an actual Anechoic chambers with real test equipment. Yeah...some sort of difference !

Nobody has mentioned the original design parameters of said moderators ? is the Fatboy Or any other moderator designed to handle high FPE (unless ordered that high ) projectiles that a lot of people mod their gun to do ?
this brings up another question . What if i buy a moderator designed for a 60 FPE gun and put the mod. on a 15 FPE gun ? Are there any unwanted "side" effects ?
 
My Tantos and 0dBs have been very effective on several 17 and 30 FPE PCPs… The Atomic XR barks loudly and is quite muffled with either of the above threaded on…. Esthetically I like the 0dBs…
I had a Tanto and a Tatsu. The Tanto was generally a better performer until I got to about 50 fpe. I have no idea why. Now I've just run a test which included the Tatsu (having sold the Tanto) and it turned in a pretty good result at 25 fpe... beats me. Maybe I should spend a little time figuring that out.
 
I was suspicious of the fatboy from its release, but I have to admit my strongest feeling was a negative one for the aesthetic. I’m never after the most quiet option, I pick the one that gives me the best results on the target.

So far I’ve been successful with one of these
DFL Tanto 22/25
DFL Tatsu 177/22 and 22/25
DFL Sumo 22/25

I did order a Huma mod 30 4/0 25 cal Avalanche this morning to try out in my Notos and P35.
How do you like the mod30 in your notos?
 
Well......I'm glad we have the Airgun community. Some very good points have been made. It's easy to start following the marketing. I also have several moderators and have noticed that they work great on a particular rifle and not so much on the others. more important is the effect on the POI either due to the weight or harmonics. Man wouldn't it be cool to try a product before shelling out hundreds.
 
After all the hypes on YouTube about ppl praising Fat Boy 2 as the next gen of moderator that is caliber interchangeable and the bulky but short dimension seemed to please these YouTubers with the sound attenuation without the tube extension, and the claim that the tube extension would bring the bark down to whisper quiet.

So I bought it with the extension tube.

I was surprised that the Fat Boy 2 without the extension tube produces loud and sharp bark. The extension is heavy and attaching the two does reduce the bark but at a level that is not proportional expected compared to the volume.

I tried to add layers of thicker insulation material to the core in the Fat Boy and use hair curls as the frame to roll the insulation with no substantial improvement.

Do I have a bad luck or it's just what Fat Boy 2 all about?

Anyway, I'm looking for the alternative which able to accommodate both cam 22 and 25, light and no bs bark attenuation and the length should be less than 20 cm.

Please advise.

Thanks.
I am not happy with the fat boy either. I have been using a sumo on my FX impact three and I like it. Compared to my sumo the fat boy doesn't cut it.
