Chinese Solvent Trap - will it make a good Airgun Silencer? 

Hi Tony, that's great, I'm glad it helped

Yes mate, very impressed, just ordered 2 more the same, but without the need for the unf thread adapter, and another, also 6" long but 1.5" wide instead of 1" wide, which in theory should be even more quiet! I will of course be testing and making a video 🙂

Thanks very much

Hi Edgar, spoiler alert...... I tried the next size up, same length but 1.5 in diameter, and it was no quieter, in fact, it was 1db louder!?

Thanks for the comment, I know what you mean, I have the hair curler mod in the original shroud of my Artemis P15 and that is quieter than with the standard baffles. Great thing about these cheap silencers is that you can experiment with different internal to fine tune them...... if you're into that sort of thing ☺️

Totally agree dude 👍👍

I did try to record the sound but it didn't come across well on the phone speaker. I will be doing an episode 2 with another "fuel filter" I've ordered which is a wider diameter, larger internal volume, so in theory will be quieter. I'll see if I can get some better sound recording equipment to pic up the differences.

Glad you found it useful mate 👍

Thanks for the feedback buddy. I know what you mean, the hammer is the loudest part of this NP-03 now!

or not hearing it ;-)

Very impressed so far, more testing to come.

Hey, thanks for watching. After testing this a few times now, I can safely say the accuracy was unchanged between using the fuel filter compared to the swift stumpy 👍

You just have to be careful when you drill the baffles anyway they are all punched in the center to help and avoid mistakes.

Totally agree dude, I'm glad they worked for your rifles. I've just had another delivered, same length of 6" but with a 1.5" diameter instead of 1". I'll be testing that to see if it is any quieter, in theory it should be.

Thanks Aaron

Thanks for the comment, don't get me wrong, I love the Swift Stumpy, I was looking around to purchase another, but couldn't find them in stock anywhere, I now know why! So nothing against the Swift Stumpy, it was just the only silencer at hand to do the comparison against.

Sorry for the late reply. I did test the wider diameter one but it made no difference, it was no quieter on the sub 12 ft lb rifle. It might make a difference on FAC rifles where more air is thrown out so the larger baffles can accommodate that extra air...... maybe.

Indeed it is mate

Agreed, they make pretty rubbish solvent traps 😂, I don't think I'll be buying another off the shelf silencer ever again!

Hi, thanks for the comment, it was max power for this rifle, but UK legal sub 12 ft lb. This rifle was producing 11.8 ft lb.

@@k.s.airguns-airgunpestcont4680 thank you for the answer my friend

Hey, none of the ones with the usual baffle configuration come with a 1/2 inch UNF thread as standard, you have to purchase one with a 5/8-24 thread and then choose the 1/2-20 thread adapter. If you follow this link (if it works) it'll take you to the one in this video, you can then choose the 4th option along which adds the correct adapter. www.aliexpress.com/item/1005001869888468.html

@@k.s.airguns-airgunpestcont4680 thanks for your swift reply. So if I get that one I can discard the the 5/8 24 part and just replace it with the 1/2 20? (The part that screws on the barrel).

@@OCDfish no dude, the adapter is just used to reduce the thread on the one end cap that screws onto the rifle, unfortunately it is not a replacement end. I was looking around for one that you didn't need an adapter for, but can't find one anywhere.

@@k.s.airguns-airgunpestcont4680 thanks. I’ve just watched the video again and it all makes sense now!

@@OCDfish cool, god bless RU-vid 😉

Thanks for the science bit 👍

This may be true, but they are for sale in the UK are air rifle silencers, and it was the only thing I had to hand to compare with. Still, it proved the point.

@K.S.Airguns - Airgun Pest Control I'm not slating the silencer, I have one 😉

Hi, I've only ever tried two types of design myself, baffles or cones, like in the video, and one I refer to as the "hair curler" mod, where all the baffles are removed and replaced by a tube of low density foam. I find the baffles are quieter, but the foam can be made to fit any length of silencer or shroud if you're not happy with how effective it is, or even if you want to change the tone of the sound coming from the silencer or shroud.

@@k.s.airguns-airgunpestcont4680 thank you very much again for the answer and I forgot to ask do you use any adapter to install the filter in your kral or just put it in like it comes?

@@hectormanuelmh Hi, yes, you need an adaptor, if you check the video notes there's a piece on what size adapter you need.

I was impressed with it.

Its fuel filter not oil one haha. And its nice to sell them with a hose (suppose for the fuel) on aliexpress :D

Hi Wayne, if you follow the link to AliExpress in the description, that product has the option to choose the adaptor you need, the adaptor you need to choose is 1/2 - 20

@@k.s.airguns-airgunpestcont4680 Is the "20" in the 1/2 - 20 measurement the thread count? And if so would a 28 thread count still work? Thinking of getting this for my flashpup .25...

@@serfillustrated4018 @SerfIllustrated hi, sorry, I'm not sure, I just googled the different adapters and find the one that would fit the standard 1/2 inch unf thread. Doesn't a .25 barrel still have the usual 1/2 inch unf thread? If you order a "solvent trap" with a 1/2 - 28, I think you can get a 1/2 - 28 to 1/2 - 20 adapter.

@@k.s.airguns-airgunpestcont4680 I'm not to sure bud. I get my .25 in the mail tomorrow. I was hoping the adapter would let me screw straight into the end of Hatsans QE shroud where the end cap goes. And then the 1/2 side would thread into the "fuel filter".. Hell, for the price i think ill order and try it just for shits and giggles. lol ..Thanks for the help!!

​@@k.s.airguns-airgunpestcont4680 NO!!! a 1/2 is an air guns size, which is perfectly legal here in the U.S.. 1/2 x 28 is firearm size and runs afoul of the regulations unless numbered and 200 buck stamp paid for in the U.S. I was given one of these by a L.E.O. and I immediately threaded the 1/2 x 28 to 1/2 x 20. Easy, peasy, no adapter needed. However, it was in my possession for a day before I could get to it. Fortunately the LEO is my next door neighbor and could run interference for me if needed. LOL! the little unit now resides on the PP-700 and does a fine job of hush-hush as I use it late at night for scorpion hunting with a black light and 3 mil green dot reflex sight attached to the PCP Pistol.

I didn't have an extra phone clamp to film it, but as you probably know, the difference in the sound rarely gets picked up properly on a videos. I will try to get some songs footage and groupings when I can get to the range. At the 10m distance I was able to shoot though, there was no change in the POI between the Swift Stumpy and the Solvent Trap.

I shall try that configuration with the dB meter, thanks Luis

😟

Hi Andy, yes, the NP-03 certainly does need a silencer, the barrel shroud does pretty much nothing. Thanks for sharing your views 😊

Haha, thanks for the feedback. But why would I make this up, I have no affiliation with the Chinese seller of this product. Watch my other reviews, I tell it how it is! If you don't believe me, spend £8 and see for yourself. Thanks again.

@@k.s.airguns-airgunpestcont4680 no that's ok people are getting in trouble in America buying these things online
