I have Weihrauch silencers on both my .177 and .22 Ultras and I cannot fault them, they are really quiet.

The weihrauch is quieter than the bsa - ive got both, but only because my BSA R10 se came with a vc on it - and i have also opened them both up to have a look inside b4 , and i found the fabric packing around the (hair curler) inside the HW to be a bit more denser than in the bsa vc, but there is not a great deal in it sound wise tbh - However if i had to choose between them, the weihrauch wins always, as its also feels more well made than the bsa vc. Ive heard getting, or changing the both inner washer/baffles to suit the right caliber helps reduce sound? but that is just hear say. Good luck m
HW is about as good as it gets for a general purpose off the shelf unit.
I tested the 4 of my 6 different Moderators i have last week when i got the adaptor to add a second one to my FN12.
The db numbers are not super scientifically measured but I did use the same meter in the same conditions at the same muzzle distance. It's a pretty good guideline.
Falcon QF - 98
Swift Stumpy - 94
ECS DeathWhisper - 90
HW - 88
Bear in mind that every 3 db is a doubling of power.
Remaining two are not directly comparable (Daystate Reflex & Falcon Male UNF)
From testing on my MK4 last year the HW does beat out the Reflex.
Only nice thing about the ECS is it's super light and matt finish.
Basically you cant go wrong with the HW - and if you don't like it they sell very well on here; always a good indicator!
Edit - I should point out these are for direct comparison only. The action on the FN12 accounts for the vast majority of the sound measured.
No, in fairness i didnt have a sound meter, i just had the ears of two other people listening, whilst i tested both, and we all thought the hw was a little quieter, thats it. But like i said there's not much in it - ive got no loyalty sway to either of them (but the rifles i own are 2 bsa's & one crosman ratty), i dont know about the A.S magazine tests? (i like this mag), but i just trust mine. I take it u have listened to both also? We shot a sub 12ftlbs rifle round out with one on, then screwed on the other, and done this several times, and found the above - I think maplins do a sound meter for about 20 quid, so it would be a good honest test if somebody on here had a decent range of the most common sound mods in their collection, anyone? I hope there is BETTER out there? as we would all benefit... (whilst i was writing this, the guy above posted - good test btw)
(I think maplins do a sound meter for about 20 quid) - SORRY, No they dont, its £50, ive just checked it - eb*y do them starting at around £20, i knew i seen them cheap somewhere...

The logun carbon fibre job what bar sells is a very effective cheap silencer but what's effective on one gun might sound totally diffrent on another band of gun![]()
The exit hole is essentially just the last baffle.
Reducing the size to suit .177 would certainly improve the performance...
The trouble is that for sub 12ft/lb air rifles there is so little air exiting the barrel that the different is somewhat negligible.
That's the main reason that most companies only off a one-size-fit-all option for air rifle sound moderators
Redesigning the shape of the baffles and air chambers can also up the performance, but there's always a cost; price, weight, accuracy etc.
It's usually a good idea to remember that the popular moderators on the market were designed by a bunch of skilled engineers and optimised for maximum results on a given budget.
I have a HW mod on a HW100, tried a Swift and a Hugget on there and the HW seems quieter to my ear at least. Neither are as quiet as a tiny, back venting mod I had made in the 90's by Jon Harris.
All much of a muchness anyway to be honest as a cheap PH mod will keep the neighbours happy and if it's for hunting then the pellet smacking into whatever you're shooting will be a lot louder.
Put on heading 270, assume attack formation
