You can suppress the hot gasses from the combustion. If a bullet is going over the speed of sound that part can't be silenced unless a certain attachment is used that decreases the bullet to below the speed of sound. A silencer in certain cases can actually increase performance (by how jsr said) and increasing the barrel length. (If the barrel length is optimum it could also increase suckback I suppose, but that would be a realllyy long barrel).

If the barrel is long enough, you don't even need a suppressor ;)

who [female doggy] and moan about everything that gets in the way of their soap opera

Hehehaahahahah!
About supressors themselves, Ive never seen a supressor (for a Spud gun) that uses baffles instead of cotton lining on a barrel extension. The only one ive seen is a little pistol made by JSR. Are they worse? Or just hard to make.

A bullet traveling at supersonic speeds does not generate that much noise. If it happened to pass you, you would hear a not-too-loud snap followed by a buzzing noise that receeds away from you IN TWO DIRECTIONS. And yes, silencers can and do affect accuracy. ANYTHING that affects the bullet during or after it's exit from the barrel will throw off accuracy. Otherwise, they'd be standard issue for every combat role in the armed forces of every country in the world. Instead, they are used ONLY for close-quarters missions where stealth is an absolute necessity, and only by soldiers who have been trained in their use.

@twizi: You can make them out of anything at all that is semi-enclosed. The most important part is the volume be large.

@Daltonultra: I am not going to claim to be a firearms expert, because I am not, but what I have learned from everywhere is pretty contradictory to what you just said.
First off, the crack from a supersonic bullet is quite loud, and for that reason, they suggest that you always use subsonic rounds with a silencer.
As to accuracy, yes, adding anything to the end of a barrel will change how the projectile flies, but not necessarily in a bad way, and not necessarily in a manner that couldn't be corrected for. As previously stated on countless other threads about silencers on this forum, a some silencers may even increase accuracy, because it reduces the muzzle blast that knocks the bullet out of line.
The other major issue, why I assume they are not used in normal combat situations, is for them to be effective, they have to be of a considerable length, which would reduce the gun's maneuverability, especially for quick deployment from vehicles and all.
Also, they have to be all the larger for automatic firing, as they tend to get 'filled' and lose effectiveness.

Not 100% sure of all of that, so correct me if I am wrong.

BMX Pegs would be a good idea, but if a suppressor is removable it's illegal, so if u do make it attach it to your launcher permantly, baffles are the way that the gamo whisper suppressor works.

just be safe and not make one, unless you want to go through the long process with the registration.

Wow, spudkilla, did you even read any of this thread? You are wrong. The legality of suppressors has little to do with whether they can easily be removed. For our purposes, they are completely illegal, no questions asked. Just read this thread and all others to get the details.

Daltonultra: mate you obvoiously don't know very much a .308 is in fact a 7.62 nato round and um guess what... I'm a an ex service man from australia. I've served 6 years with the navy reserve as guess what? A bosuns mate with a navy marksmans rate.
Ok if you lash a silencer or even a suppressor onto a .308 as you put it. It would make 5 times the noise of a .22 have you ever been around one of these bad boys going off? I've hurd everything from a M16 to a AUS88 styer in 7.62 and 5.62 with and with out suppressor and silencers and there is no way there quiet. you might quiet down the gasses but you cant shut the bullet up.

Scilencers and or suppressers DO NOT effect accurcy and in a fact the australian navy AUS88 styer is fitted with a supresser on the muzzel. I can put 10 shots into the bottom of a coke can at 500 yards. if it so greatly affects accurcy how is this possabe? second to the fact. i have seen my uncle put a head shot on a turkey at 100 yards with a scilenced .22 a turkeys head is no bigger than 2.5 inches.
My friend time to go back to school. my previouse statement stands.
Rank amatures.

another thing if you have been around fire arms as long as me and my family you can locate a suppressed shot by ear up to 1 km away.
and yes there are quieter ways to kill someone I like your mag light idea lol. but their is always the trusty old shang hi or even a tribushe. you dont get blood on your hands that way.

I think we can all agree that supressors are a very touchy subject here, but most people are ignorant of the facts, and seem to go off of what they see in movies, worse when they defend their false beliefs to the grave.

Yes, dude, I frakking know what a .308 is. It's the Winchester round that came out 2 years before NATO adopted the case as the 7.62x51mm, so STUFF NATO nomenclature. I also know that you meant to say Steyr AUG F88, not "styer AUS88".

BTW, you haven't heard either an M16 OR an AUG F88 in 7.62, because neither was ever made in that caliber. And WTF is 5.62 other than sloppy typing?
The Steyr AUG is made in 5.56, 9mm, and .22, but not 7.62.
You MAY have heard an Armalite AR10(doubtful), or much more likely, an AR or M-forgery uppered in 7.62, but the M16 was manufactured EXCLUSIVELY in 5.56x45mmNATO.

NO I meant to say AUS88 styer is actually the designation for the Australian version of the AUG. it stands for Australian 1988 issue, and lithgow small arms aka BSA adapted it to a 7.62 20 years ago.
it also had a barrel increase from 16 inches to 24, as it replaced the SLR (self loading rifle and my all time favrot.) it also being 7.62, why down grade when you can engineer to suit. the 5.56 you mention is on the SMG version of the AUG and has a 4 inch barrel with 40 round mag. my 7.62 had a 30 round mag with select from 3 round burst to single shot to full auto.
It is Australia's front line combat rifle. Just like the M16s that came out here, it has two actions one being 7.62 the other 5.56. in Australia where upgraded them to suit our already in service cartrages. this is so we can utalise fallen enamys ammunition in our own fire arms, eg vertnam war battel for Long tan, Australian soldgers used ammunition taken from dead VC's AK 47's, in there australian issue SLR's, and won the battle.

The cartridge you mention 7.62xi51mm has never been sold or manufactured in Australia.
7.62 or .308 same cartridge.

Oh yeah so sorry my finger sliped when typing 5.56.

I know my fire arms I used when i served and i knew what ammunition was required to operate my fire arms.
I'm not going to further this argument as i can see that you are very very un informed. My advice go back to school get some knowledge under your belt and some experience. It has been shown from your lack of rebuttal on the other issues that in fact you do not know what you are talking about. Don't belive everything you see on TV and the movies.
The whole reason you have these places is so that you can talk to people who are in the know and have done things before. consider your self educated.

Good luck
