Looking for a Neighborhood friendly Silencer for the Huben GK1 .25

[dmeenzer]

Hello together,
i want to buy a GK1.
But all i know is, that is a very loud Air Pistol, without an Silencer.

Is it possible to silence the GK1 at full power in .25 so that it is suitable for use in the neighborhood?

Which silencer do you have on the weapon?
I find it very difficult to imagine that the original Huben silencer with 26mm/132mm makes the weapon quiet enough.
I am curious to see what kind of silencers you have on the GK1 and whether you can use them to make it suitable for use in the neighborhood.

Thanks in advance!

Kind Regards
dmeenzer

Don’t shoot in your backyard with a full power GK1. That’s a 80 foot pound mistake waiting to happen. Unless your neighborhood consists of acres in between neighbors, the range is better suited for a full power gk1.

If worried about sound level, that means I have already resolved my “Backyard” power level by choosing 5-7fpe

If the gk1 is as air angry as my leshiy 2 was, the only thing that seemed to silence it was the bohemoth. Great silencer for the money, and you can add or remove sections to tune for how much, or how little noise you want.

80 FPE YIKES! how many shots would that power get ?

I don't know how quiet you can make an 80fpe quite. I have a gk1 in 177 with a custom carbon fibers shroud moderator. It's so quiet you could be standing right next to the shooter and you wouldn't know that it was a gun and went off.

Thank you very much for your Answers.
I'm not interested in always shooting at full power, I'll rarely do that, but it would be cool if you could shoot at full power and not bother anyone. A silencer is currently being built based on my idea for the GK1, let's see how the performance is. I'll report it if there's interest here. But I will mainly use the GK1 with significantly less power, I don't want to have to constantly refill the Huben GK1. Let's see, maybe I'll buy the Huma Regulator, so I can experiment with it. Quick question if someone has installed the regulator, is it still possible to use the power screw in the handle and use it to additionally regulate the power?

I have the .25 with a Donny FL TANTO - 1.22 x 5 Inches

.22/25 1/2 x 20 It does help with noise, but border line back yard friendly.​

I'm using a subscriber bore test .22 ldc on my .25 gk1 shorty amazing how well it works and pretty dang light.

The gun does more than 80 fpe the hugget mini makes is neighborhood friendly sounds like a nail gun sort of with the moderator

Yes, you can silence a .25 for backyard use, but you do not need to shoot with energy levels higher than say about 40 lbs. If you adjust the power to about 700 fps, you can shoot one full magazine (17) starting at 300 bar and end up with about 220 bar left, which will give you 17 rounds at a very consistent velocity. I then recharge the gun back to 300 bar from a bottle in about 10 seconds. Do not shoot the gun without a pellet, because of the way the valve system works as the muzzle report is much louder. On another point, I make my own silencers and I use a much smaller moderator bore size than most commercial moderators. That makes my moderators quite a bit more quiet than commercially sold mods.

Huggett Standard/Snipe worked best for me soundwise, but I found that all disk-baffled moderators are almost twice less accurate at distance compared to the Impulse Air 1200 with 2 extra baffles (6 in total), I think because it has connical baffles. IA-1200 +2 baffles is almost as silent as the Huggett, "almost" doing a bit of lifting here - you can live with it and its acceptable. The problem with the IAs is that its impossible to get extra baffles in the EU, you have to buy 2 IAs and combine them, and just the one moderator with plain 4 baffles was way too loud. I suppose the IA-1350 might work slightly better but I have no experience with it and I can't compare them.
I check moderator alignment with a carbon rod from a 5mm (or was it 5.5mm) bow arrow, with scotch tape wrapped around the end that goes into the barrel so that it fits correctly.

Accuracy issues with the use of moderators on GK1s can exist because the moderator adapters also clamp the shroud to the frame. If the shroud is not perfectly square to the frame, barrel bore misalignment may occur. I wrote about this issue in earlier posts. It is the primary reason most commercial moderators use a much larger moderator bore than really necessary as it reduces the chance of clipping. Just another reason to always use an alignment rod every time a mod is mounted on your air gun.

Had this one made for doing bench work and a super anal permission that doesn't want to hear anything louder than a snap.

I have a GK1 V3 in .22 and added the Huma regulator. Yes - you can still adjust the power with the screw in the handle. I have the regulator set at just over 100bar as it was delivered. I haven't tried to wind the power up very much. I was more interested in shot count. I'm shooting just over 20joules - about 15fpe and get 3 mags full with consistent power. I have DonnyFL moderators - the Yokozuna and Ryu - both are equally effective.

Phil,

Thanks again!

Matthias - one thing to be aware of is - unless Huma have updated - the gauge they supply can't cope with 5000psi. Doesn't stop you filling it to the full pressure but the gauge goes off the scale - so I rely on my compressor gauge to know when to stop!
