i have this one.
i always wondered what the differences are between the shroud vent sizes. mine blows a pretty decent amount of air per shot. noticeably more after putting a moderator on.

i always wondered what the differences are between the shroud vent sizes. mine blows a pretty decent amount of air per shot. noticeably more after putting a moderator on.
From what I have heard/read, having the shroud with the vent towards the back reduces the noise a good bit. I wanted to get a CF shroud when I got my first K1 but I'm not paying a few hundred $ for a shroud
Nº 98 (Former Nº 109) · Complete Barrel Shroud for Huben K1
This is the complete shroud for the K1's barrel. Available both in carbon fiber or aluminum and for both calibers (.22 and .25). The Huben shroud covers the barrel and also provides for sound suppression.

Btw guys don't forget that NSA makes .223 ammo as well.
.223 | 36.0 gr | 215 Slugs | $0.084 /rd
Our ammo is only for use in Air Guns. Our air gun pellets/slugs are swaged from soft lead to give excellent expansion for effective and responsible hunting. This is a hollow point nose with a flat base. This slug is .223" diameter and not typical size for most airguns. Make sure your airgun...

I’m not a fan of venting lead dust towards my nostrils. I do not understand the logic in this design. I prefer the vents away from my face and using a moderator.From what I have heard/read, having the shroud with the vent towards the back reduces the noise a good bit.

When I decided to put a moderator on my .22 K1, I thought about it and figured that the holes in the shroud would be counter productive. Why let air out before it passes through the moderator to be "moderated"?
So I built my own "baffle stack" out of left over Marauder baffle cones, by taping them together after cutting one shorter to get the correct overall length, and then wrapped the front and rear ends of the stack with enough electrical tape to cause enough of an interference fit with the shroud that air could not get past and thus the holes in the shroud were effectively blocked off.
Even though the stack was sub-optimal (because it was a smaller diameter than the shroud, thus left dead space that could have been used for expansion) the new home-made part resulted in a quieter shot cycle than the stock baffle stack. As an added bonus, accuracy was a bit better too . . .
Then even better than that, I found on here a 3Dprinted all in one custom baffle insert that did the same thing as mine without the wasted space, plus it was made with a bit of "Tesla Gas Diode" tech too. It proved even quieter than mine, and kept the same accuracy benefit too. Unfortunately, that member no longer lists them for sale . . .

Interesting, I figured someone by now would've had either a 3d file for it or made another one. I haven't been able to find anything.

Yes, I can't find it or anything like it either. The old post on it is gone, but that member is still here - I can reach out and see if he still makes them, or has the file on it . . .
Unfortunately I don't have a picture of it (I used to just direct people to the thread that had it), and I don't have time to pull it out now as I am getting ready to leave on a trip. But it was about 3.5" or so long and was a snug fit to the bore of the shroud, and it was directional in terms of air flow (obviously, given the baffle design). Sorry I can't help with a picture . . .

No worries, if you can get any info from the member or tag him on here that would be helpful

@JaceSpace1369 Nail on the head my friend. After your post, I looked at old invoices and I found out that I bought these AVS slugs when I bought the rifle. I just got around to shooting them. Thank you.

@JaceSpace1369 I only shot them out to 40 yards to notate a few holds. They shot well. I did notice that they don’t seat (move) much at all when inserting them into the mag. Even putting more pressure at the base of the slug with a seating instrument pushing them in they don’t move much at all. As a result, they can slide back when I tilt the rifle up. I used a half of a q-tip to attempt to seat them. I’m not sure if this is more of a length or diameter thing. I’ll have to take more time with them, chronograph them, take some measurements, and pay closer attention to their length in relation to the length of the chambers.

it's a diameter thing, if the slug isn't wide e ough it won't engage with the grooves. The peanuts don't even engage, but the 3rd band prevents then from falling too far and jamming.
I ended up putting a slug backwards on purpose to see what would happen and it goes in about 1/3 of the way and then just sits.
You could try the same thing and actually push the slug in to seat snug and then push it out and measure the size.

@JaceSpace1369 and @Ezana4CE,
I contacted Jake on the insert and he is still making them. Here is the link to to his posting on it. Don’t know why I could not find it before . . .

I should be receiving his shroud insert sometime this week if the post office in CA gets their act together. It's been floating around the facilities since last Tuesday. I am also receiving a .218 sized Huben Magazine from Kelly on Tuesday so I will see how the .218 slug and .217 slugs fit and measure them, then test them throughout the week.@JaceSpace1369 and @Ezana4CE,

let us know if the inserts make a noticeable difference. i ended up making a silencer for mine and it makes a world of a difference. if the insert can bring the sound report down as much as the silencer i made, i’ll use that instead. i wanna keep the k1 as short as possible

i don’t have a meter to measure the decibels but it’s definitely quieter with the moderator on. im shooting 36.8gr nsa at around 930fps and i can hear the slug swishing through the air into the distance. i think it’s quieter than my notos.

Here is what I found on my gun with Jake's insert a few years back, copied and pasted form an old post:
Here is what I got in dB levels as measured in my finished basement with the phone about a meter from the muzzle (with lots of potential echo sources, but over carpet). The Huben is a .22 shooting JSB 18.1 grain pellets at 920 fps, and the LDC is a Huma Compact .30 cal (oversized for multiple uses and best accuracy). Of course the values below are only good for comparison to each other, and probably don't represent a "good" number of the actual loudness, since it is just a smart phone app and also was not done in the open. But they match what I hear on a relative basis.
Factory baffles, no LDC: 115 db
New Insert, no LDC: 112 db
Factory Baffles, with LDC: 107 dB
New Insert, with LDC: 102 dB
