sound suppressor

Not all sound supressors are illegal. As i have said ones used by wildlife control purposes can be purchased for this use. Alberta has a store that sells them.
There are criterions that make some sound supressors legal.
I have already explained this previously on this forum.

I would think that DFO & Conservation officers would also be able to possess & use suppressors in their line of work due to their Fed/Prov. enforcemnt affiliation.
From I read of the Firearms act/Criminal code, us Civilians are sh*t out of luck as far as owning/using suppressors.
SKBY.
Which store is that the only people that are allowed to posses Suppressors are Licensed dealers, Law enforcement agencies ,Military unit it does not allow individual Members either Law Enforcement or military to purchase them. By definition any device that alters or reduces a firearms report is considered a Prohibited device ,Ownership by the General public is Illegal and carries a mandatory prison sentence.Provincal Conservation Officer's I believe fall under LEA's in most provincesNorcyaddict762 said:

These guys have the right idea about suppressing heavy machine guns.
I knew a Canadian who had a .22 rifle with threads on the muzzle ... His new wife was French and she kept a few of her first husband's gun things (he'd died young). The nice Canada Customs officer was inspecting their household goods - his coming home from a European posting and hers as settler's goods. 'What's this?', asks the Douanes person, holding up a cylinder about 1"x8". My friend says, 'I think it is a silencer.' 'OK', says the Customs Officer and goes to the next big box. So there is at least one legally imported silencer. And I really don't remember the man's name or much detail .....
I was however curious on an intellectual level and tested various BB, Short, Long, Long Rifle and High Velocity .22 shells to advise him on the gun's performance. The slower the bullet, the softer the coughing sound. The slowest bullets did not cycle the action. When the action did cycle, it was the same click and snick as dry-firing or hand cranking the parts. The accuracy was about the same with or without the suppressor.

I posted this a while ago on the old board.
Its a Norinco .22 with sub sonic amunition.

And for comparison a 22 magnum shot a couple of minutes later in the same spot.

We cleaned the silencer before we used it. It had been in storage and looked like it had'nt been cleaned in a few hundred rounds. It was simple to clean. Unscrew the end, take out the baffles(they look like washers) give them a quick scrape and wash, then slide them back in and you're good to go.

BTW this was in NZ where its legal to use supressors on ALL calibre rifles.

Why are they illegal?
Because the vast knowledge of the ruling class is obtained by watching Chuck Noris films. If they would seek the advise of experts, or anyone who has ever owned a firearm, we would have laws that make a shread of sense.
*not to slag on Chuck Noris or nothing*

Blasphemy!
A suppressor will always sound quieter in an open field than in an enclosed area like a room. The bullet will still make a sonic crack if it's going faster than the speed of sound wether it has a can or not, but the location of the shooter will be very hard to pinpoint by anyone within earshot.
OH my GOD! Nobody called me ?
OK, here goes. There is very little concensus on EXACTLY how silencers work but at a basic level, every suppressor is a kinetic energy trap. That is they trap and then release kinetic energy in a slower manner to reduce the magnitude of the energy available to produce sound that we hear as a "bang".
There are hundreds of different silencer designs that all work in a slightly different manner. Depending on the beliefs of the designer. Personally I think there are a number of factors at work inside a silencer and they are all affecting the noise reduction. These factors include but may not be limited to: Expansion, trapping, reflection, turbulence, heat absorption and resonance.
CRAP! Muzzle blast is muzzle blast regardless of where the firearm is fired. Inside a room, the muzzle blast and sonic crack are reflected back towards the shooter making it appear to be louder. In a field the shooter never hears the sonic crack cause it propogates away from the shooter's position. If you put a sound meter on both cases, it would show the same peak noise level.
True. Steel wool probably works more from the point of heat (energy) absorption. Steel wool is not the best material to use cause it can burn.
Pretty close. Keep in mind video cameras limit the noise of the shot and are not a good comparison tool.
CRAP! A silencer is classed as a "Prohibited Device" the same as lots of other prohibited devices and carries no level of punishment greater than any other prohibited device. To my knowledge there is no such thing as a "mandatory" prison sentence in Canada. Not to mention most LE/legal types have no idea how to properly sound test a silencer to determine if it even is a silencer.
Depends on the can, its construction and the caliber. The majority of rifle caliber cans are essentially self-cleaning and tend to be of sealed steel construction these days. Pistol caliber cans are more often made of aluminum and do need to be cleaned on a regular basis.
In general, a steel rifle silencer should last the life of several barrels meaning they are pretty much maintenance free. No parts touch the bullet so there is no need to replace anything.
If you want to learn more about silencers, how they work and what exactly is inside them, buy the books, Silencer History and Performance Vol 1 and 2, which are available from Amazon.ca.

Otherwise, go to the Silencer Tests website http://www.silencertests.com and troll through the Images Gallery. There are lots of pics of internals to see.
MMMMMmmmmmmmm .................... O .... K ......... If you say so.
Otherwise, not something any of us should be discussing, here or anywhere. However in some parts of the world these sorts of things are not criminal. Here is a pic of a pop bottle silencer adapter.
You are refering to the infamous "Hush Puppy". Wipes are not commonly in use in the West anymore due to some stupid laws but they can still be found on Combloc silencers.
In this pic the plastic disks are new wipes, which will typically last 20-50 shots.
Yes, ALL silencers are illegal for civilian ownership in Canada and NO, there is no store that sells them, anywhere in the country. Any government agency may purchase silencers, this includes, the military, law enforcement, provincial and civic government agencies.

Interesting topic. I always thought the wipes would have "flaps" that opened - I didn't realize they started out as a solid piece.
Anybody have a cut-away view of an integrally suppressed barrel? I assumed that they just drilled holes in the barrel, added some stand-offs and then wrapped the length of the barrel in sheet metal (creating a void to bleed off fps, cool the gases, and mufflle the sound), but that's just a wild guess.
I'm still holding out hope that someday we'll have a government that doesn't pass laws based on what they see in the movies.

Not everything uses K or Z baffles. The Surefire cans use flatish, stamped baffles, the SWR cans use something called an Omega baffle, B&T and Knights both use a slotted or crimped cone baffle and the SRT uses a highly modified cone baffle called the #####. So there are lots of baffles out there that are neither a K or Z.
As to the "bevelled diversion passage pairs", those are a highly specific structure in one type of baffle used by one company. They are not at all common.
This is a Mickey Finn designed, modified K baffle that is commonly used by B&T. It does NOT contain bevelled diversion passage pairs.
Sometimes they do, I just couldn't find a picture of that type. I'm sure there is one of the Hush Puppy can on Silencer Tests, I just couldn't find it.
The only real difference between a muzzle can and an integral can is the barrel porting. Most modern integral cans use similar types of baffles as a muzzle can. Integral cans are quickly becoming dated as muzzle cans almost always outperform them with less complexity.
