If its attached it ain't if its detachable it is...

In a time if you pee behind a tree your likely to be classed as some kind of terrorist, I highly doubt they will allow PB silencers in any way shape or form in any near future.

I had to do that dance the one day with a cop friend. I disassembled the one I had planned to swap between markers as it was detached and just did the same thing to an old cocker barrel I had laying around. Same silencer but suddenly legal.

I personally don't get how my pvc pipe and foam contraption could lower the report of a firearm...as it would most likely melt. It's not like we have to slow the projectile down, all we have to do is absorb the excess gas exiting the barrel.

So what paintball manufacturer will go out on a limb, make a marker with a fixed and unchangable barrel just for a stated >8dB change in sound?

I can only assume that the change affected on the .22 would be similar to that for a paintgun.

We will see?

So if you make a silencer and attach is to a paintball marker barrel with one dot of JB weld, does that count as permanently attached? (seriously)

Where is the defining line for permanently attached? Also does the barrel have to be permanently attached to the gun as well as the silencer or just the silencer?

A one shot firearms silencer would still be considered a silencer, even if it melted right after the first shot. In fact, I suspect you could make a very effective and cheep disposable silencer, perhaps from a coke bottle or something along those lines. How many shots do you need to commit murder?

Don't forget, there are also other sounds to deal with as well. You have to think of the firearm, or the paintball marker, as an entire package.

If you really wanted to you could make a relatively quiet paintball marker, without having to skirt the law. I've seen a few low pressure markers with nicely ported barrels that were relatively quiet.

Pay the $200 fee to the BATF and you're good to go.

Because that supressor operates under the same principles as any other supressor does for any other application. Consider this:

Firearm noise comes from three places.
1) Action - Hammers and other mechanical noises the gun makes during the firing cycle.
2) Expanding Gasses - the *KaBOOOM* sound that guns make when fired
3) Ballistic Sonic Boom - Noise generated by the projectile traveling faster than sound.

The first source there isn't much to be done about without re-working how most firarms work and the noise generated by the action is so minute compared to the rest of the stuff that happens that it isn't generally a problem.

The second source is where the supressor comes in. Through a series of baffles, layers of material, and even puddles of oil or water, expanding gasses are captured, cooled, and allowed to exit in a more controlled manner. This is where most of the noise generated by a firearm shooting subsonic ammo comes from, the same is true with paintball guns, internal combustion engines, etc.

The last source is generally dealt with not so much by designing a supressor to slow a projectile down (though they do decrease muzzle velocity) but by simply shooting subsonic ammo. There are certain supressors which require hypersonic ammo to work correctly (the MP5-SD comes to mind) because the baffeling system in the supressor ends up removing the vast majority of the propellent gasses from behind the bullet making a round which might normally fly at 1400fps only move out at 900fps. Firearms, such as the AR-15 which use a .223 REM round equipped with a "can" generally see a reduction in report on the order of 20-30db. This however still means that they've very loud because, while that reduction is significant, they still have the report of a ballistic sonic boom which weighs in at around 140db.


Finally, in order to make a supressor for a paint gun w/o actually paying the BATF (you still need to do the paper work and file to even consider making one of these, if the device is proven to be sufficiently unalterable then you get the device back and your $200) you need to make the supressor part of some other portion of the paint gun such that disassembly of the gun prohibits the supressor's use with a firearm either by physically disallowing the insertion of a firearm, rendering the supressor useless while the gun is apart, and making it such that any attempt to remove or alter the supressor from the paint gun renders it completely unusable.

If you afix a supressor to any barrel (welded there or not) the barrel can be cut off or simply removed from the paint gun and used to muffle a firearm. If you weld the barrel to the gun, again, the barrel can be cut-off and used in the manner described in the second post.

The biggest problem I'm seeing is the caliber of the projectile we use. Since it is such a large caliber it means that pretty much any firearm is going to be small enough to use it. This however isn't the case when it comes to certain pellet guns which feature integral supressors because, first they're small caliber and second they can afford to have a complicated disasembly because they don't need to be taken apart all that often in the first place.

If someone came out with a paint gun which featured an integrated supressor you'd be looking at a design which will largely, and most likely, be something along the lines of a Tippmann with a cast reciever in halves. Even then I can see ways to make the supressor work on a regular firearm.
