Questions about: Noise, Barrels and Porting

[famousgamer]

Okay. My goal is to make a very silent barrel/marker. How does one do that? With a silencer, or sound dampener of some sort, and some carefully planned sound baffling, I think.

So, I was wondering a few things that you all may want to help me out with...

- When you got a nice quiet 14 inch carbon fiber or ceramic barrel, with about half its length in parting (making it real quiet) how much sound really comes from the porting? Much at all? If you totally silenced the tip of the barrel, but left the porting alone would it still makes much noise, or is the porting in need of supression as well?

- Would the best silencer filler (in a long PVC tube) work better as a sound dampener (like rubber foam), or as a gas absorber (like steel wool or cotton balls?) Maybe a bit of each? Foam on the outsdide and wool on the inside?

Thats just the start, Im sure. If you have any input into the silent marker/barrel design, please contribute here. Thanks.

I'll leave it to others to go into all the specifics about how paintball silencers are illegal.

[famousgamer]

Yeah, they are illegal in some areas. Cetain states allow them tho. Internationally there are entire countries that allow them. I am in Canada, and I am allow to use a paintball silencer for my paintball marker. Therefore lets not get into the whole legal/illegal thing, okay?

[paullus99]

Well, you should be more specific - since down here, the ATF has said to 99.9% of silencers for paintball.

[famousgamer]

Okay man. You know, there is an entire globe that uses this forum. Like... a whole world of different peoples and governents. This is not an America only forum, and even if it was there is no law against talking about silencers. There just isnt.

You can go online and find plans for bombs, and setting them off is illegal. You can find articles on growing pot, but doing so is illegal. Etc.

Lets move on please thanks.

There is site I'm sure then about making silencers...

If I was to want one for paintball, I'd look for a Barrels of America ie B.O.A /concealer. It has a factory silencer.

When I use to play woodsball back when, a friend of mine made one of PVC, regular cotton and everything was all wrapped up in black duct tape. He was shooting a tippman and with his little homemade invention....I can honestly say it really worked. Don't get me wrong, his marker wasn't totally silent, but it really muffeled the sound and when he picked us off sometimes, when walking back I couldn't tell my other teammates exactly where he was! I just said, "watch out Dexter is close by!".

I recently bought a dm6 and that marker is very quiet. I tried a friends carbon fiber barrel out one day and I must also say that the carbon fiber barrel/dm6 combo is a very quiet set-up! I think the carbon fiber makes a difference because it had similar porting to my barrel but my marker fired way quieter w/ the carbon fiber one but just not as accurate.

I tried finding out how to make my marker as silent as possible also, but nobody really has some solid info. I was even able to buy a dvd on "improvised silencers". It's a great educational tool, and you really understand the concept of it all, but applying it to paintball is something else. If your interested in the dvd....let me know!

I hope the little info. I have helps in someway. You should try to find a scenerio type of forum and I bet there is someone who has tried making what you are looking for, and might have had better success at actually making one. I know how it feels when your looking for info on how to make a silent marker...just don't say silencer because you get all that crap about "silencers are illegal" and blahblahblah...yadiyadahyadah!

From my past experience I use to shoot a 68 automag (pretty quiet), All american barrel 16in, and the PVC/cotton/duct tape type of invention . It worked pretty well for me, but my gun wasn't totally silent...just a little more quiet! Well hope you achieve your goal someday!

[famousgamer]

Thanks dood. I am using the a classic mag myself actually. Thanks for the read and the encouragement. Ill let you know how my inventions turn out.

[master_alexander]

on my z mag i have a really really heavy barrel. it is stainless steel and stuff. annyway its quiet but has a ring to it when you shoot it. lol. still awesome.

also like carbon fiber barrels, something about they way they are ported makes them so quiet.

carpet padding makes a good filler material also making the outer shroud out of a thick pvc like schedule 40 or schedule 80 pvc .... the hardest thing though is makeing the ends, especially if you want to make it so the shroud can be pulled of off to clean or change the filler material.

The BATF has historically confiscated BOA Concealers and has labeled them as Firearm Suppressors.

check out your local ATF because they changed the restrictions on paintball silencers, plus they were never illegal in the first place if you filed the right paperwork

[paullus99]

$200.00 is a lot of money & the paperwork is, in itself, quite a chore for a noise suppressor, for a game....not that I didn't have one back in the day - you can get just as quiet with a carbon fiber barrel anyway.

Just my point of view, no reason to go jumping down my throat -

[Stealth Fighter]

You can do it in the U.S. Just don't get caught.

The change in law implemented for Paintball Silencers was for a suppression device which could not be removed from the gun or barrel (i.e. permenantly attached). Such suppression rulings aren't new, and there are a few Airguns that anyone can buy which have integrated silencers. The refference to the "making tax" paper work is correct, however for most people's purposes going through the legal motions are too much of a hassle.

Also understand that anyone who wants to have a quieter report from their paintabll gun won't see a huge improvement in terms of muzzle noise. Silencers on real firearms only get to around 30db of noise reduction, and when the un-suppressed report of the firearm is well over 140db, that ain't much though it is enough to take the edge off and even save some hearing.

There are/were some sound files of VM68's being fired with regular brass ported barrels and a BOA Concealer. The difference in report was marginal, though the suppressed report deinfately was dulled so it sounded more as a tock rather than a crack.

EDIT: Suppression is greater with sub-sonic ammunition, 30db suppression is taken from a .223REM Suppressor.
