Airgun Technologies Agt Uragan 3 compact .22 more silent

I have Agt uragan 3 compact model with 400mm barrel.

Very nice and accurate gun.
But i need get it more silent.

My shooting is mostly for backyard and gun need to be silent.

Short and light gun is also handy and what like use.

I have test stock + moderator adaptor M14x1.25 Female to 1/2UNF-20 + Weihrauh Xl moderator.
Too long setup for short gun and good if can have little more silent.

Also test bare barell + moderator adaptor M14x1.25 Female to 1/2UNF-20 + Weihrauh Xl moderator.
Too much noise.

Today did arrive Huma-Air Modulair Airgun Moderator MOD40 Avalanche moderator and one extra modul
chamber.

It was possible to get it M14x1.25 thread so it can be shorter without any adaptor.
Moderator length can also adjust and it easy to open for cleaning, etc.

With that extra modul it is more silent when without it.
Still too loud, but really nice to adjust that moderator length shorter or longer.

Next need to adjust fps little lower, but not happy to mess up agt factory tunes, because it shoot so well.

Now that stock uragan shoot Jsb hades 15.89gr cal .22 for 930 fps.

I have test more heavy pellets, but they need to too heavy when it is silent.

Target is tune gun for 15.89gr cal pellets and about 880fps.
Hoping that it still shoot precise after that tune.

My other pcp hatsan is tuned to shoot 870 fps and it is very silent.

That uragan 3 can be different to tune what was uragan 2 are.

Is that hammerspring adjusting good way to start for that tune for uragan 3 compact?

Or need to adjust regulator or some else?

I thought my Uragan compacts were loud until I let someone else shoot them. The reason I‘m telling you this is because with all the different things you’ve tried, you think the gun is still loud. AGT‘s are mechanically noisy suckers right next to your ear. That’s why no matter what you screw onto the end of the shroud, the gun sounds the same.

If your gun isn’t quiet with that giant thing you have attached to it in the photo, the mechanical noise the gun makes is playing tricks on you.
 
Thanks for your answer.
Yes i can hear that there is more mechanical noise from uragan what is comparison that Hatsan bullpup.

That Hatsan was also more mechanical noise at stock perhaps for hammerspring.
After regulator install and tune it 130 bar with hammerspring adjusting that mechanical sound did also lost.

Uragan 2 models have that de-ping sound and that was also one reason to buy uragan 3.

With that longest moderator combo it is most silent.
That agt stock moderator is not necessarily the most silent option and it also quite long.

Shooting Fx hybrid slugs 22 grain at 800 fps uragan was very silent.

Fps speed lowering also make dirrerent for sound so i would like to test how good combo for speed, sound and accuracy is possible to get.
Also hoping that is possible to achieve with quite short moderator.

Yesterday i also did test that Huma-Air moderator for Hatsan.
Test was shoot and remove one moderator chambers at time.
Moderator did work very well even there was only 2 chambers in use. Gun was shooting 870 fps.

Top of picture are startpiece for huma.
Below is agt stock moderator parts.
