A. §921(a)(24) The terms "firearm silencer" and "firearm muffler" mean any device for silencing, muffling, or diminishing the report of a portable firearm, including any combination of parts, designed or redesigned, and intended for use in assembling or fabricating a firearm silencer or firearm muffler, and any part intended only for use in such assembly or fabrication.

Numerous paintball silencers tested by the Firearms Technology Branch have been determined to be, by nature of their design and function, firearm silencers as defined in 18 U.S.C., Section 921(a)(24). An individual wishing to manufacturer a firearm silencer must receive prior approval from ATF by submitting an ATF Form 1 and paying a $200 making tax.

Gun silencers are really easy to make...

But aren't paintball guns quiet enough anyway?

Maybe I'm not understanding it.

• The barrel/shroud combination is unquestionably designed to quiet the report of the marker. "Quieter operation was one of the design goals for the Stealth Barrel and how it got its name."
• The design is probably legal for the following reasons
• The additional length probably has as much to do with the sound reduction as anything else. (Longer barrels use more air to get the ball out, thus utilizing the excess air pressure that is responsible for the report of the marker.)
• The porting can not be taken off of the barrel and put on a real firearm.
• The shroud is the only part where the legality of this system can be legitimately questioned, but the following should be considered.
• It is unlikely that the shroud, designed specifically for this marker, could be installed on a real firearm.
• If it was installed on a real firearm, it could not possibly provide a silencing benefit unless the firearm barrel was ported* to release expanding gasses from firing into the shroud.
• If a real firearm barrel was ported in such a manner, it is unlikely that the plastic shroud (if of similar quality to the standard ones I've examined) would survive the experience of firing.
• Finally, the very description offered in the article brings into question if the shroud can actually help quiet the marker at all. Remember that porting quiets the report of a regular marker by allowing excess gas to escape gradually as the ball travels down the barrel as opposed to exiting the end of the barrel suddenly and expanding with a loud pop. Now consider the following statement: "The interior support walls of the Stealth Barrel foregrip are of a smaller diameter than those of the short foregrip, and the Stealth Barrel has a smooth polished outer finish, rather than bead-blasted, so that it can fit snugly into the foregrip.  The fit is so tight, in an effort to prevent air – and sound – from passing between the chambers, that the Stealth Barrel ships from the factory lubricated with grease to make installation and removal easier." It sounds as if the tight fit of the shroud would defeat the purpose of the porting. (If the air can't escape the chambers, the back pressure would prevent the ports from operating at full efficiency and you would still have excess air coming out the end of the barrel.) If I would have to guess, based on the information provided, I would say that this barrel is probably quieter due mostly to it's extra length.

My purpose-less post was uneeded, Kaybeck owned this one.

Nice to see Kayback posting again.

Anyways, for the guy on the last page, the A-5 stealth isn't advertised as being any quieter. The "stealth" line of markers are geared towards sniper wannabees, so they used a catchy phrase. They aren't saying the gun is any quiter, since a flatline is usually louder than a normal barrel.

Again, if silencers are legal in your area, for the proper tax stamp you can own one. Most things are legal if you have enough money.

Supressors on rifles, or anything with supersonic ammo do hide the source of the shot well. In a few weeks you're going to experiance rounds going over your head while you're pulling targets in the pits, you'll understand how your hear the noise coming from the bullet itself and it's not really traceable.

Try it. I can't tell if you are being sarcastic or not. Sorry if my joke meter is out of whack, but it's not the ball's friction that makes the sound, it's the higher than atmospheric pressure propelant gas exiting the barrel that creates a pressure wave that your ear interprets as noise. Cutting a barrel will INCREASE the report of a paintball gun. You could, if you were a better mathematician than I am, build a "silencer" for your paintball marker by INCREASING the length of your barrel. How farI have no idea, but you'd need to drop the propellant gas down to the same as the atmoshphere, where ever you are playing. As I said I've no idea how long this barrel would have to be, but you don't need any porting, or shrouds, or anything. Just a hell long piece of barrel :p KBK Jesus, it was a joke.  I knew it would make it louder and wanted some  "sniper" to try it.  I figured it would be rather funny, him trying to be all stealthy and what not sneaking through the woods only for his gun to be super loud.

Too bad the smart ones know better-- >:-)

i just realized when snake posted how old this thread is....why would you bump it?

and why do paintball guns even need silencers? who cares how quiet the marker is?

It seems people on this board really hate the words "Silencers" and "Suppressors", and go on and on about how illegal they are. The construction of one these days revolve around fitting a shroud to a ported barrel.  This concept has drawn a lot of hostility from people who claim that even posting such information is related to illegal activity. That being said, how do all of you feel about Smart Parts Stealth Barrel kit?  How is it that a ported barrel with a shroud is illegal but, yet, SP is going the distance in making sure people know about their new stealth barrel kit? Do you think it's jsut a matter of time until the ATF comes along and shuts them down, or is all the hoopla about about paintball silencers (ported barrel w/shroud design to be specific) jsut a bunch of hype? Don't know what I'm talking about?  Click http://www.warpig.com/paintball/technical/paintguns/smartparts/sp8/stealth_rails/ - here . Keep this discussion civil please. have you ever heard or shot an sp-8 with the "suppressor barrel" for it? it does not silence the gun at all, i find it just as loud as the shorter stock sp-8 barrel.

But that's just it....it's not ALL THAT LOUD....after listening to the reports of an A-5 sounding off, for example, the SP-8 is a whisper in comparison....yes, it still makes noise, just somewhat subdued.....it works for me.....so unless folks around here wanna send SmartParts a mass e-mail campaign, tell 'em that they're full of beans, and have them put the cards on the table and show tangible proof of said silencer/supressor capabilities,  I say "Who Cares??!!??" 

I just wanna play.
