Hey all, I’m looking for some mod recommendations for the Huben GK1. I’ve got mine tuned for 1 mag, ~45 fpe and the buck rail mod I’m using currently isn’t really up to the job at this power level. Width is an issue here to not block line of sight, length not an issue at all. The combo of short barrel, high power, and shroud instead of direct barrel attachment makes this tricky, so I’m all ears to any advice. Thanks!
Quieter than quiet GK1?
- Thread starter LayeredOgre
- Start date
There was a 3-D printed design from a member here, "subscriber" that handled the problem with the front sight by being asymmetrical, with a larger volume below the centerline. Baffles were designed in such a way as to minimize asymmetrical airflow experienced by the pellet, a pretty well thought out design. It must be in one of the GK one threads here, I will look for it and if I find it post back here later. Perhaps @subscriber will be online here and chime in. There was another member who was printing these designs for a fee. Reports on their performance were all very positive, and they are available in several different lengths.

Go to the Gateway to Airguns forum look up Rocker1, and PM him for a LDC like this one in the video

I'm using a subscriber offset design that lets you see the front sight. I use a red dot on my shorty .25.

Also have a smaller design by subscriber that you can see the sight. Might need them printed 100% infill I'm set at 25fpe .

I have heard that the GK1 is extremely Quiet if you do not move the trigger at all
(sorry just could not pass opportunity up / maybe to much coffee this AM ? ) )

Well you’d think that! When I’m not moving the trigger it actually still does make noise from my jaw hitting the ground after seeing the groups and chrony strings. Seriously the only thing I don’t like is the noise at its current tune which is inevitable I suppose.I have heard that the GK1 is extremely Quiet if you do not move the trigger at all

I have printed many moderators from mono, to all sorts of baffle designs for my air guns. Petg is best with 4-5 walls and 40% infill. I will be printing “subscribers” and excited to see their capabilities.
From the reports, these are better than what I have tried and that is fantastic.
For now, The impulse air 350 is the best I have used but requires a dif sight. I am using holosun 507c so no biggie. If you want to tame it further you can add an extra baffle or two. My DonnyFL tanto and fatboy 2.0 are nowhere near as good as the ia350.

Doesn't anyone like the original Huben moderator? It had a unique baffle system inside and works decent for quiet the pistol. With a moderate tune, my .25 is fairly quiet shooting heavy 34 grain pellets at 810 fps.

It’s just that the impulse air is much quieter and modular which is what the op was asking for.

I have a Huma Mod 40 in .22 on mine. It is the quietest of the moderators that I have tried on the gun - including a Falx High Flow. Obviously it does not work with the Huben sights, but does fine with the red dot. It is the quietest gun that I have.

Thanks to all for the advice! I need to give a huge shoutout to subscriber who set me up with his STL files and print specs. It might be a bit until I’m able to try my luck at printing them but will certainly share the results here.

Subscriber was kind enough to share his files and they are currently running on my printer so they will be ready to put through the paces when i get back home. I am very excited and love how this community shares. Very cool.
