Thanks, & great info. I have been using the JTS & they are accurate and seem to fit pretty snug in cylinder.Got my ares mod adapter today and was able to expand my accuracy testing at home. The GK1 .22 was tested at 50y, clamped in a vice, to eliminate the human weak link. Pellets only today. All the JSBs from RS through redesigns. Five H&Ns including FTT and Baracudas. Several JTS and a few other oddballs. The clear winner (again) was Predator GTOs which are staggeringly accurate. The best of the rest were the JTS Dead Center 18.1grain domes. They were substantially better than any of the other lead pellets. Everything was shot at 890.
I joined the party!
Won't get a chance to pew pew tonight...will have to wait til tomorrow

On the back I use the rear sight elevation screw, only longer. on the front you have to remove the dowel pin to locate the shroud. I tried using small vice grip but keep slipping off, finally I clamped it to my milling vice ( gun upside down) and while pulling on the grip I wiggle the grip and it came off easy. I then installed the barrel shroud tight and tapped the slut for M3. Only other issue was torx screw on top of the action, I had mill a clearance hole for it. You can drill it with 1/4" drill and it will be good.
Yeah, it's the mod30.Thats a Huma, right?
What model / size exactly?
Thanks,
Matthias
I’m not sure if I missed it, but what moderator do you have on it? Looks like the sights are unobstructed.Manage to get my Ruger 10-22 Docter sight base on yesterday and mounted advance optics micro dot. Wow I'm loving this more and more. getting 1-1/2" groups at 30 yards with my old eyes, yes I rested the tank on sand bag. Had to repurpose one of my Dewalt tool bag as it won't fit the oem case with the micro dot.

The threads look to be the exact dimension of the specifications for 1/2" X 20 and 5/8" X 11 for the insert, so if your printer prints them out too small, here are some revisions to @subscriber 's files with enlarged threads for printability just in case that proves to be an issue for you. You might want to try printing just the threaded portions of each first to see which one gives you the better fit.@subscriber - thank you so much for sharing your design! I know what's up next on my printer!
I still need to do more testing to verify, but so far it has seemed to me that the longer the suppressor is, the more drop I tend to get irrespective of weight.Got the ARES adapter also. Very impressed by the machining. Used it with the Donny FL Sumo. It decreased the sound level by 10 dB and did not affect pellet velocity at all. On other guns using the moderator increased the velocity.
What surprised me the most, is that it also changed the point of impact on the target. With the moderator on, the pellet was 1" lower and 1" to the right at 10 yards. Was hoping to not have to readjust the sights when putting the moderator on. There is no indication that the pellet is striking the moderator.
Curious what others have observed?

I was actually thinking of printing just a section of the printed threads not only to test fit but also to see how it clocks on my adapter. Then add-in what I would need from a 'shim' perspective so I don't have to mess with sep shims.The threads look to be the exact dimension of the specifications for 1/2" X 20 and 5/8" X 11 for the insert, so if your printer prints them out too small, here are some revisions to @subscriber 's files with enlarged threads for printability just in case that proves to be an issue for you.

Now off to the printer for me too. Thanks for sharing subscriber! ♥

Sumo making barrel droop? Snug the adapter more to minimize any barrel wiggle?Got the ARES adapter also. Very impressed by the machining. Used it with the Donny FL Sumo.

Do you have any interest in an offset 3" printed one? I could modify my 4.25" design into a 3" length easily enough, I'm guessing it would still probably be more effective than a Fatboy, regardless of it only having an endcap baffle and being shorter (I've found with my designs/testing so far, less usually tends to be more when it comes to baffle count). If that is of any interest to you or if anyone else is interested in one that short, let me know and I'll print one off to test.I have a small STO LDC that is 1.3" in diameter and only 3" long. It does a great job of sound attenuation, but and it blocks the front sight. It seems a 1" diameter is the perfect size. I have an older Rocker1 LDC that is 1" diamer and the iron sights are completely usable, but it's 6" long and does cause the POI to drop a good 3-5 inches at 15 yards over a bare barrel!
I'd love to see something that was 1" diameter and no more than 3" long! If it had 3 baffles I think it would still have a decent amount of noise attenuation!
Thank you, but I'm trying to keep it to where it's easy to holster and draw without having to fight with it. A 1" diameter would pretty much maintain the barrel size and with keeping it around 3" long, it would not be as awkward drawing it from the holster as it is with a 6" extension of the barrel. So far I have not found anything commercially available with those specs. I sent an e-mail to Huub at Huma-Air to see if he'd consider making a MOD25, but never heard anything else...Do you have any interest in an offset 3" printed one?

I made my own, cf tubing. 22mm OD and 20mm ID, with 5Maruader cones inside. I machined front and rear cap for interference fit.I’m not sure if I missed it, but what moderator do you have on it? Looks like the sights are unobstructed.
