[@alaric_]

Although the absolute claim that "no gun can't be silenced to the 'thump' heard in movies" is wrong. Personally having fired a subsonic .22 from long a barrel rifle with a silencer, you would be hard pressed to hear anything similar to a gunshot. Shooting .22 Short from pistol with a silencer is so silent that the sound from the bullet hitting trees is louder than the report. 'Silentness' didn't improve anymore when we fired .22 Short from a long barrel rifle with a silencer. Very lethal but so little powder charge that it fails to cycle the gun (decreasing noise) and as the magazine is for .22 LR, bullets have to manually inserted. With many downsides comes great stealth.. As with everything, it's all about tradeoffs, nothing is absolute. In this case: more damage, firerate and/or accuracy and you will get more noise, quaranteed. Vice versa applies equally. I will grant that the movie-portrayed 9mm or larger caliber guns cannot be totally silent but the fact is that there definately is totally silent guns. The question is who wants to pay the tradeoffs for them.

I'd also like to point out that the decibel scale is an exponential one: An increase in 10db is a 10-fold increase in power. Reducing a gunshot by 50db is therefore a reduction in acoustic power in the order of 100,000. Suppressors then are actually highly effective from a physics perspective, but that's not how hearing works. It is however key to hearing loss, and as you mentioned, very important for indoor civilian use - not to remain unheard, but so you don't deafen you, your friends, bystanders or even the people you're trying to subdue.

[@keithhartless6352]

Glad somebody caught this. -3dB is half power; as you pointed out, suppressors actually reduce noise substantially. Notwithstanding, this is a supper video on the topic.

[@itsapittie]

A small correction... The sale and/or possession of suppressors has never been banned in the US. The 1934 NFA made them a restricted item requiring special licensing and payment of a fee similar to machine guns. Unlike machine guns, the manufacture of suppressors has never been banned. If you aren't a criminal or otherwise prohibited by law, it's perfectly legal to buy or make a suppressor after you pay the $200 fee and wait for approval from the ATF. However, like almost everything in the US, the states have individual laws on the subject and some jurisdictions don't permit citizens to own suppressors. The inclusion of suppressors in the NFA was based entirely upon hysteria and not reality. There's no evidence that suppressors are or ever have been used to any significant degree in crime. I'm aware of only one instance in which a shooter used a suppressor and it didn't keep anyone from immediately identifying the shots. The only noticeable changes that would result from removing the restriction on suppressors are that people would be less likely to lose their hearing and at a distance you'd be less likely to hear the shots of hunters.

In addition to less propellent, the weight of the bullet itself can be increased in order to reduce the velocity to less than the speed of sound. That is, it takes longer to push a heavier object up to a greater speed. A shorter barrel will also help, as bullet velocity increases in longer barrels (to a certain length, based on the ammo) as the pressure is allowed to affect it for a longer period of time. So, less propellent, heavier bullets, and shorter barrels can all help us remove that crack of the bullet.

I am absolutely impressed by how accurate and thorough this video was! I'm very well familiar with firearms, suppressors, and all of their myriad real-world uses. This is one of the only videos I've seen on KZbin that didn't leave me shaking my head. This was really very good work! I don't have anything I really want to critique about it, but I would like to include some additional information in case anybody with the interest to read it comes across my comment! Oh, and thank you so much for not discussing the trend of using oil filters as suppressors. Yes, sure, it can work a little, for a bit. Good luck getting a proper sight picture, though. The suppressed cartridges invented by the Russians were also used in a knife. The idea, I suppose, being that if a soldier was attempting to neutralize a sentry with the knife, but their target turned around, they could then dispatch them with a silent bullet, instead. No idea how well this worked in practice. Another interesting note about those cartridges, and the ridiculousness of our ATF over here in America, is that here, every round would have to be registered as its own suppressor. And to legally own them as a civilian, you would have to pay a $200 tax on every single cartridge. The MP5SD is a sub-machine gun that I really expected to be in this video! It wasn't really needed to explain the potential of an integral suppressor on a firearm, though, since there were other adequate examples. I will say this, though. That particular weapon was known to produce such a quiet report that the cycling of its mechanical components was noticeably louder than the shot itself. Also, while it did still make a sound, it wasn't easily recognized as a gunshot, even at relatively close ranges. Both of these things were discussed in the video regarding other weapons, but hey, if you're new to the subject, and interested in it, the MP5SD is definitely an icon of the suppressed tactical firearm world. Finally... there is even a suppressor out there that fits the minigun. Yeah. The rotating-barrel, ridiculously high rate-of-fire minigun. No idea how well it works, because I can't afford to own either! If you actually read all of this, you're awesome. Here's another bit of suppressor-related trivia for ya, since you're so dang dedicated to the subject! Suppressors tend to push a lot of combustion gases back into the barrel of a firearms. In semi-autos, this can mean increased fouling, increased operating forces within the action, and, maybe happily, in a full-auto it usually causes an increase in the rate-of-fire. This also leads to the user of said firearm breathing in more toxic substances, like lead particles, so suppressors as a means of keeping the shooter healthy aren't exactly perfect!

[@cliffisfree100]

I own suppressors for hunting. The movie industry is why i have to pay the Gov $200 to have one to save my ears. In England, where they have the most strict gun laws, they are sold over the counter and its rude not to use one for hunting. In America, the gov gets rich off of tax stamps for each one.

The only part he really missed was that one of the primary methods to drop rifle calibers into the subsonic realm is to increase the mass of the projectile(measured in grains). Rounds like 300 AAC Blackout have projectile weights ranging from around 120gr to about 220gr. The lighter supersonic rounds carry more energy because of the squared relationship of velocity and kinetic energy but they produce a very loud supersonic crack even when suppressed. The lower velocity 220gr still carry a fair amount of energy down range but sacrifice the range and energy of their lighter counter parts. This can also be balanced by switching to even larger rounds like the 9x39 and the 458 socom which can sling significantly heavier projectiles down range and carry more energy while still being below the speed of sound. Otherwise, he pretty much nailed it. Good on ya Simon.

[@harrkev]

Is there such a thing as a "one size fits all" barrel twist rate that can stabilize such a wide range of bullet weights?

That works for pistol calibers too. Standard 9mm target rounds are 115 grains and NATO military standard 9mm rounds are 124 grains, both are supersonic.

To suppress something is to remove it from perception. To suppress sound is to remove the sound from perception, also known as silencing. When you suppress a rebellion, you don't remove half the rebels and leave the other half fighting in the streets. When you suppress the truth, you don't execute half the dissident reporters and leave the other half around. Etc. It's like people who think "accident" means "couldn't be prevented", when it has actually meant, for like 600 years, "something bad that happened" and, for like 100 years, "not on purpose". And, oh, how they'll "correct" you when you use the term correctly.

[@geodkyt]

One correction - the NFA didn't *ban* silencers in the US. It bans the possession of one that isn't properly registered to the lawful owner and hasn't had the proper taxes paid (which were set in 1934 as roughly equivalent to half the cost of a new automobile, specifically to discourage use).

[@TheWeeJet]

Really that's what a ban means in terms of guns. Really nothing is banned if you have correct licences. For example did you know that following the same rules you can own just about any type of gun in the UK. But its commonly thought that anything more than shotguns or bolt action hunting rifles are banned in the UK. Basically when you need anything more than the basic licence it's seen as banned to the general public. Also fun fact in the UK silencers are not banned as is often actually recommended if you are going to get a rifle licence as they are very easy to get. I don't actually personally know anyone that has guns who does not own one.

@@TheWeeJet A ban that exempts people.who manage to get licenses for professional use (for example, in the US, licensed manufacturers of machineguns, who are permitted to make new MGs for police, the US military, and US State Department approved exports; note they don't have to have an actual sales contract to build guns, which is where "post-May dealer samples" come.into play...) is not at all the same as a system where any law abiding adult citizen can have something, provided they fill out the paperwork and pay a tax or fee. Silencers (like "pre-May 1986" transferrable machineguns) are not banned by the federal government, just highly regulated. ANY law abiding citizen age 21 or older who is permitted to possess even the least scary type of gun (say, a single shot .22 rifle or .410 shotgun) can lawfully buy a silencer (note, their state of residence may absolutely ban them, but that's a different issue) - it's just a lot of paperwork, a one time $200 tax per silencer "transfer", and a wait of many months. The federal government *literally* has zero discretion to disapprove the transfer, provided the buyer doesn't have a statutory disqualifying factor (criminal record, etc.) *But*, a silencer that was *imported* after 1968, or a machinegun that was imported after 1968 or manufactured domestically after May 1986, that private citizen is legally prohibited from ever owning - the only route for anyone except a government agency to legally possess one is if they are licensed to work in the business of silencers and machineguns - and those licenses are only authorized for you if you are actually conducting the business of making or selling thise devices (there isn't even a "theatrical" license like many countries have for prop houses - every Hollywood prop house that has a license of this type is actually a licensed manufacturer, seller, or importer, who *must* do business in that field to keep their license.) Thus, "post-1968" imported NFA items (silencers, MGs, "sawed off" rifles and shotguns, "destructive devices" like cannons, etc.) And "post-May 1986" MGs are *banned* - the only private citizens allowed to own them are those who have government licenses to conduct business in those items. There is a "loophole" for "post-1968", but not "post-May" MGs, "dealer samples" for the licensed NFA businessmen *if* they were a "sole proprietor" business (not a corporation or a partnership) where they can keep possession of the dealer samples that aren't "post-May" MGs when they go out of business.

Suppressed rifle calibres, like the .300 Blackout, operate on the principle of using a very heavy-for calibre bullet/projectile, with a very fast twist to stabilize it, so that sonically it will leave the muzzle below the speed of sound, yet carry enough inertia to damage it's target, and be ballistically aerodynamic to have practical useful range. In the case of the .300 Blackout, they use a 220 grain or heavier bullet, with a phenomenal ballistic coefficient ( aerodynamic profile, to keep the bullet speed as high as possible over the distance of it's flight to target) and a rifling twist rate of 1 turn in 7 inches, to spin the long bullet fast enough to keep it flying true. The subsonic round then benefits immensely from the suppressor at that point.

I have an adjustable gas block and silent capture spring which have allowed me to make my firearm very quiet. Yes there is noise but it doesn’t sound like a gun shot. I like my suppressors because of the decrease in noise pollution as well as being another step of hearing protection.

Correction on your correction. The ATF doesn't require a $200 tax for each wipe and a wipe isnt considered a suppressor itself.

Same reason oil filter suppressors are not popular, once the original oil filter is used up it's back to the manufacturer for replacement you can't legally just buy a oil filter at the auto parts store and replace it yourself, the only way you could do it yourself would be to pay the 200 bucks for another stamp for another serialized filter which I doubt any dealers would do.

I didn't know the science between a gun silencer/supresser, but I knew a gun supresser didn't "silence" the gun and I'm glad you showed the science behind the how and why.

[@AleksandrKramarenko]

@@BareSphereMass I was pleasantly surprised too. He nailed it... almost. Right at the end he got it wrong on suppressive fire. He said it's a big deal when you can't hear the gunshot, but this is false. Suppressive fire effectiveness is mostly decided by how loud the supersonic crack is and how close you can get the bullets to impact next to the opponent. It's actually more intimidating when you hear the crack nearby, you see the impact nearby, but you cannot figure out where the shot came from. Also, US Marines are introducing suppressors to regular troops. This indicates it is a good idea to use suppressors for regular troops. The only real down side is logistics (another thing you need to manufacture, ship around, maintain, etc).

[@3-gunjack368]

Appreciate the honest information given! I will add that it's relatively easy to achieve "Hollywood quiet" gunshots using manual action 22lr rifles and commonly available subsonic ammunition like CCI Quiet. The tradeoff however is you're firing a bullet so small and slow that it's effectively an up-jumped BB gun. I know I can say that sport shooters like myself would all be grateful if suppressors were deregulated, because hearing loss is a major issue, especially amongst hunters who can't wear hearing protection and still hunt effectively.

I've heard that when the lawmakers we're drafting the NFA, they only included silencers because they didn't want poachers to be as effective. Considering this was during the great depression and people were starving...they obviously didn't have their priorities straight. But I also heard they put in silencers.....without even discussing silencers. No reason whatsoever.

[@ZE0XE0]

ive heard that the very very first drafts of it were going to be targeting specifically pistols and nothing else. And then everything else evolved from there. That's why short barrel rifles and shotguns and AOWs (Any Other Weapon classification) were added to the title 2 firearms list, along with the initial intent to ban handguns, it was part of an attempt to stop drive by shootings from prohibition era gang violence. Why the politicians decided on the minimum barrel length for rifles being 16" and the minimum for shotguns being 18", likely nobody will ever know. Why they arent either both 16" or both 18" seems like the most bizarre thing of the whole law. It makes absolutely no sense for there to be different length rules... And to add another detail to the anti poaching comment, the lawmakers were largely misguided in that endeavor as bullets from most rifles and pistols move faster than the speed of sound, so even without a silencer, the bullet will impact the target before the sound from the muzzle reaches the target. So regulating silencers to stop poaching, was not a sensible thing.

[@shawnwillis7561]

@@ZE0XE0 nothing about the NFA makes sense. The reason they set the tax at $200 was because the Thompson cost $200. Back then that was like buying a car.

The NFA of 1934 didn't outlaw silencers/suppressors in the US. It regulates and taxes their sale. The $200 tax in 1934 was a decent deterrent to sales. In the 2010s and 2020s, the $200 tax is not such a big deal.

[@northgeorgiaclearing6982]

It bugs me when channels that present facts get details wrong. I watch a lot of Simon’s channels but when he covers topics I know well I often find inaccuracies.

[@LazyPervySage]

The $200 isn't a big deal anymore but the ridiculous 7-12 month wait time for the application to be approved is. So you pay depending on the caliber of the can anywhere from $300-1200 plus another $200 then fill out and sign paperwork. It gets mailed off to the ATF to then wait months for it to arrive to an agents desk for review and approval. That's if there is nothing filled out incorrectly or in the wrong box. If there's something wrong it's sent back and you correct it and try again. That is why it's not widely used here in the US hopefully this Efile system that was added for form 4s actually cuts down on wait times but it's still going to take longer than it does to buy the actual gun you attach it to.

[@croe5357]

He didn't say it outlawed their sale. He said it outlawed their private sale. Which it did. In the state that I live in, I can privately sell you any of the guns that I own without getting an FFL involved. However, if I were to sell you any of my class 2 devices, we would need to involve an FFL that is authorized to deal with NFA items.

[@PrayingPanda]

Well that's just not true. The law reads that they are banned EXCEPT /UNLESS you go through this very particular process. 7 states outright ban them regardless of what the federal process is and most states (all but 3) ban them unless you go through the federal process. Suppressors Before 1934: shall not be infringed. Suppressors after 1934: illegal unless you get permission...but only in certain circumstances and certain areas. Also it's pretty elitist to say $200 is no big deal. Sure it's not the 4k that it would be if it was adjusted for inflation but 200 is still quite a bit. The cost is one of the big3 reasons why there isn't more adoption of NFA items.

[@azmodaiNO]

The reduction in recoil and muzzle flash is understated here. That is a significant advantage for snipers and hunters.

[@Cybrludite]

And for police raiding meth labs.

[@raletky]

It depends on the gun and caliber that is being suppressed. I've fired my AR15 suppressed. With standard velocity ammunition, hearing protection is still needed. Standard velocity .45acp suppresses very well and .22lr sounds like an air rifle.

[@alandoesstuff.1254]

Using subsonic ammo with a quailty gun and suppressor is quiet. Heck, a 22LR rifle with 22CB ammo (and no suppressor) is about the same loudness if dry fired or fired with ammo. The snap of the hammer alone. I also think you are wrong about soda bottles as improvised suppressors. It provides a place for much of the gas to slow down before exiting the bottle again reducing the sound. Hell even oil filters work. The trick with any improvised suppressor is it much attach with out leaks to the host weapon.

[@SgtGigawattz]

[@cesaravegah3787]

Short answer: Yes Long answer: Even the best ones only reduce the noise and flash by a fraction, for supersonic ammo the noise reduction is not even a thing since the bullet makes noise itself with the shockwave through the fly, not only with the initial detonation, even so, silencers or supressors can be useful under some circumnstances, particularly, as implied, with subsonic ammo.
