What They Don't Tell You About Suppressors

[@BrassFacts]

Some people are thinking I am saying a suppressor is useless for the shooter on supersonic rifles. That couldn't be further from the truth. To be sure: Basically all serious rifles probably need a suppressors, regardless of use case. What I (clearly unsuccessfully) tried to say: Relatively performance between cans, in my opinion, in the context of a fighting rifle. Is only one, less important, piece of the pie when compared to all of the other factors (flash, tone, signature etc.) Also, the sound report were filmed with a nice studio grade mic, but absolutely isn't the correct mic for this type of work. There is a reason why I don't say "20%" better. I just used my personal anecdotal experience and notes from that day, which result in "slightly quieter" "functionally the same" etc. Which is the most I can do given my equipment.

[@beardoe6874]

It sounds like I should get a flow-through can for my PCC when I'm getting urban. Then I should wear ear protection for pretty much anything bottlenecked when I need more velocity, penetration or range and I should get a big performance can for my 1,000 yard plus bolt actions when I'm getting rural.

[@RedDawnReadiness]

I mean from what I know it does depend a lot on the round and speed… 556 is hard to suppress as it’s a bullet designed for speed and speed is going crack and make noise… subsonic ammo as I’m going a lot slower, limits range capabilities really the only thing I see a suppressor for is 300bo subs or even 308 subs 556 subs are basically inefficient however if you have neighbors and shoot on your land a suppressor seems logical or even cqb scenarios without ears it’s a mine as well cut down on sound

[@theimmortal4718]

Back in the Iraq war, I carried an M4 with a Gemtech Halo 5.56 can in the streets of Baghdad. A few points- 1. A suppressed rifle virtually eliminates echo in the streets. The sound seems to be absorbed by the surrounding buildings, meaning it's harder to hear a street over. I took shots less than 100 meters from adjacent units and they had no idea 2. It heats the weapon up much quicker. Fine for most contacts, but in a break contact it could cook your gun after 2 or 3 mags pretty nicely 3. It makes a big difference when firing inside a building, especially through loop holes, masking the noise to the target as well as reducing the blast to the shooter

How much would prices tank if suppressors became over-the-counter like they are across the pond? Do you think they'd become lower quality, borderline consumables like Hop alluded to in his Puppy Dog video?

[@BrassFacts]

I think we would certainly have those types of suppressors. The hearing safe act birthed a bunch of companies aiming to do exactly that. But I we'd still have current high end suppressors as well.

[@highdesertdrew1844]

I've worked on/with a number of suppressed designs, the thing in design meetings, is we can make really really good suppressors, but they aren't as durable, or won't last as long as another design. Or they require precision alignment to fit a tight bore, etc etc. Even then, the margins on suppressors is huge. except maybe for the 3d printed cans, anything conventionally machined is going to be fairly inexpensive to produce unless it's made out of space age unubtainium alloys. It's pretty easy to have a swissturn machine making 316 stainless baffles all day.

[@inferninx]

If we don’t have to wait any longer, I’m sure people would buy the high quality ones enough to lower the price on them in general. Scales of economy make things cheaper, but demand also makes price go up if supply is limited, especially if they can’t keep up with it. 🤷‍♂️

Props for discussing the glowing popsicle, while it may be far-from the here&now for this to impact a civilian. It's a clear and overlooked drawback outside of military uses.

[@ExpatriotSilencers]

Our perception of suppressor relative noise level is greatly affected by the frequency tone of the suppressor. We perceive low frequency sounds as quieter, even if they are not. A good example was a 45 cal SMG that had a nice, low frequency report sounded quieter than a 9mm SMG that metered 10dB quieter. That is a big difference.

[@Wilfmott]

that's only true if your definition of "quieter" is peak sound pressure, which is a dumb definition. lower frequency sounds in fact will impart less stress and hearing loss on the cochlea than high frequency sounds of a lower dB. they are therefore in fact quieter if the definition of quiet is practical and sensible and not a ridiculous pedantic standard of what a meter can detect

[@ExpatriotSilencers]

@@Wilfmott The only problem with the introduction of frequency into the definition of "quieter" is that it is highly subjective. Two people will not perceive the same noise the same way. The sound meter is not subjective, which is why we use it.

But seriously, don't feel like you'll die if you dont or that you'll magically become become a tier one guy if you do.

[@nick3d155]

Something that is grossly misunderstood in the suppressor realm is also that 3db+ is DOUBLE THE SOUND PRESSURE. So 97db to 100db is double the SPL. it's approximately every 10 db with no change in distance from sound source that the perceived volume doubles. But SPL kills hearing, so saying every 3db increase is twice as loud is true in the sense of hearing loss potential!

[@That_Guy5575]

For the (potential) future video about suppressor covers: One option to look at is a carbon fiber cover. While hella expensive, and I think only made by one company, seems to me that would be the best option. They have models that mount to the rail or to the suppressor, and it allows air flow for the can while still shielding against both visual and heat. Also, since shot show is coming up, check out the Senex Arms guy and his prototype AR(-ish) bullpup in the works if you can. Just watched Hop's video about the bullpups (again) and made me think of it.

Suppressors are for home defense as well. Imagine something goes bump in the night. Next a window smashes, it's real bad guys are coming in. You grab your 556 unsuppressed 11.5 and fire it inside versus firing a suppressed 11.5 556 inside. One you might get some hearing damage the other you might not ever hear again. Suppressors while not hearing safe, certainly better than nothing and certainly will take the edge off in a home defense fight.

[@Enjoyer.762]

These days, despite that more jurisdictions have favorable use-of-force self-defense laws such as the castle doctrine (no duty to retreat in one's home or property), that anti-gun lib district attorney will still politically prosecute you for woke reasons.

[@DaleErnieMichael]

You're not going to go permanently deaf from shooting a gun indoors once, there's plenty of legitimate pros to using a suppressor without resorting to blatant nonsense that a hundred million people can tell you from personal experience is just plain wrong. I've shot tons of guns without ear pro including up to .308 indoors and I have excellent hearing according to my yearly OSHA tests, I don't think my grandpa had literally ever worn hearing protection shooting even when taking CCW classes at crowded indoor ranges, and there's a ton of videos of FPSRussia shooting machine guns and blowing up cars with no ear plugs including a 3000 round belt dump from a minigun. I don't choose to use a suppressor for home defense because it adds a bunch of length to the gun and hassle just to get in the first place, I wish I could get one in ten minutes at a gun shop but I'm not too broken up about not having one for home defense and neither should anyone else be because they're not going to need to learn sign language if they don't have one. Silencers were invented by the son of the guy who invented the machine gun because he went deaf after firing hundreds of thousands of rounds to showcase his cool new gun, that's not a realistic scenario for someone defending themselves who statistically will only ever fire two rounds if any at all.

[@swissarmyknight4306]

I can personally confirm that you won't go deaf from firing a rifle indoors without hearing pro (based on experience, I'm not a doctor, so maybe "probably won't go deaf" since I've never even heard of such a thing). Now I do have some pretty epic tinnitus...

[@p99guy]

Using a USAF GAU-5 in the early 1980’s was my introduction to short 5.56 guns used indoors for CQB. By the 1980’s the Vietnam war vintage moderator, was was supposed to tame the 10.5” firing signature to approximately that of a regular 20” M16, were carbon caked solid on the inside and not disassemblable, so ours were just replaced by a standard birdcage…. Great skycop guns, light&handy as a patrol carbine, carried in an M60 spare barrel bag. But in actual firing, it was subjectively louder than a M60 machine gun. Nobody wanted you next to them on the Combat Arms Range! Including a M60 gun team. It was a good substitute for a flash bang, we joked. We realized why 9mm smg’s will never totally go away ( because they are whole lot quieter, even unsupressed) The only thing these days that Make short rifles, and SMG/PCC roughly equal is the use of .300 Blackout subsonic and a good suppressor.

[@TheMinutemanArmory]

Have a Surefire SB2 and AEM5 for my 5.56 rifles and Sandmans for my 30 cals and 6mm. Cans optimized for the cartridge fired significantly reduces the flash signature, but using universal or larger bore for smaller bullet cans will produce fireballs. 5.56 SBR's will always have a lot of flash. I've yet to shoot my SB2 at night, but on my 14.5 Geissele SD it is extremely pleasant to shoot even without ears. The AEM5 is the best, but optimized for longer barrels. The reversion chamber over the barrel plays a major part in reducing the fireball as well as the minimized bore on the front of the suppressor, but the downside is mounting it and needing absolutely perfect bore alignment. Ask me how I know.

I'm currently at the point of indecisive craze when it comes to suppressors. I've been trying to pick one for purchase for almost 6 months now but some kind of information or contradicting statement will come out about this or that...

What would you recommend best for my situation? I almost decided upon a 5.56 surefire suppressor but then a buddy of mine said I should only stick to flow through suppressors only.

I'm considering picking up a 9mm can sometime this year; I'd like to have something for my subgun and carry guns.

@davidnuxoll7074 5.45 lol. Shooting 4x per week lol. Even if this were true, what do you think you're accomplishing other than excessive lead levels in your blood? There's a point of diminishing returns. You even complained about developing carpal tunnel syndrome. Hit the gym 3 to 4 times per week and range 1 once per week. The average civilian defensive shooting is 87% of the time between 3 to 5 yards.

[@Kenposhinobi]

I’m a PewScience Nerd and reference it for all of my purchases and then cross reference it with mounting,length, weight flash suppression etc. my most recent purchase was the new CAT WB QD in Inconel and the CAT ODB QD Ti. The Inconel WB is 0.8in shorter then an RC2, is at muzzle and flash suppresssion levels of of the RC2, backpressure/shooter’s ear level of suppression equivalent to the FLOW762 and Velos LBP. It will be replacing my CGS SCI SIX on my main squeeze 12.5 mid gas, and my SCI Six will go on my backup 11.5 LPVO Setup. I got the Ti ODB to go on a 8in 300BLK build and my 20in 6.5cm AR10.

I've had my SureFire SOCOM 7.62 since the Obama years. It took a year and a half in those days to get through the ATF bs. I love it with my piston guns, but it gets my DI guns filthy fast. I wonder if the new pass through suppressors would be better in this area.

[@lipidi1542]

21:41 ONEPIECE MENTIONED! Are flowthrough supressors still a rarity in the US?

[@goawaybaizuo]

I'm really excited about additive manufacturing with advanced plastics and polymers. Ivan made a video explaining the basic thermodynamics of plastics and why they don't melt into goo like people think they would. Also, I'm sure Griffin would love to get you some cans. Even if you're not an 07. They may be able to help! My HRT 556 is phenomenal for flash. From what I hear, they have some cool stuff in the works.

[@Soloong_Gaybowzer]

From what an old SF veteran told me when I was in the Cav, suppressors reduce muzzle flash and report enough that it makes it harder for the enemy to pinpoint your location past 300yds using standard ammo. And for anything within 200yds you need to use subsonic ammo. Keep in mind that the standard firefights the grunts ran into were at ranges of 300yds or more.

[@williamflowers9435]

Midnight Brutality also demonstrated the value of a suppressor when shooting at night, with or without nods and with white light.

[@formulafist3681]

The main issue using one value to report suppressor performance such as dB is like @brassFacts said the human perceived audibility of the muzzle report is very dependant on the frequnecy content produced by the suppressor. Human hearing follows a dBA curve where the human ear is much less sensitive to low frequency compared to midrange frequncies. Also perceived loudness at the shooter and positions around the shooter are highly dependent on the geometry of the can muzzle causing variation in the directionality of the sound propagation. Also as you pointed out the sound drops off much quicker when further from the shooter compared to near the shooter. This is due to being in the far field vs the near field of the acoustic source. In the far field the sound level drops by 6 dB every doubling of distance. In the near field this is usally closer to 3 dB. If you ever plan to do a future video simular to this there are pretty simple apps and or software to analyze the frequncy content of the audio recording. It would be interesting to see if there was a correlation to your preceived loudness to the tonal content.

[@Johnny_Cash_Flow]

I'm at 13 months waiting for the release of my suppressor. It took half this time to get my TS/SCI, which I've held for over 20 years.

[@WearilyCorrect]

What are you thoughts on a 10/22 pistol with a suppressor? Mine is stupid quiet and reliable with bulk. Even better when i use the good stuff.

[@baddadjokes9330]

4:33 I appreciate the graphic utilizing the army men figurines.

[@je-rc2cl]

Thought on signature... picture needing to shoot a boombox speaker in the dark. Would it be easier to hit a visually dark speaker emitting a loud noise or a more quiet, but still perceptibly noisy, speaker with a blinking light on it? Good flash supressor > silencer for me, especially at a fraction of the cost, less maintenance and no paperwork.

[@crowsbridge]

308 with a brake on a 12.8" barrel, I'm fine. Hey, at 13:43, what watch are you wearing?

[@iFixRandomThings.]

You are correct on night vision picking up the report due to combustion/heat seen in the gas exiting the barrel-night vision devices like yours can detect low into the IR spectrum, hence the higher report under NVGs.

[@loneczgunner6562]

I buy cans that take dead key mo. Its what all my rifles have for muzzle devices and I think they work great. I don't do mag dumps though mostly just shooting prone. Works for me and I enjoy them and keeping my hearing while still enjoying my hobby. Nomad L is stupid quiet on a lot of guns. If your barrel is 16in or under, nothing will make a huge difference. Just my experience.

[@luggnutz]

MP5SD, old school I know, is a unique weapon in that you use super sonic and the weapon is designed to scrub the speed off the projectile thereby reducing the speed to subsonic which make it decently quiet. I can also attest that a large can reduces flash and sound by quite a bit. I fired a Remington 700 in 5.56 modded by LaFrance with a super long can that was both threaded at the front of the muzzle and well down the barrel which helped to reduce the overall length of the rifle with suppressor, when shooting non-subsonic you could hear the mechanics on trigger squeeze and you'd only hear the projectile as it was headed down range, basically it only sounded like a supersonic air rifle.

[@randyreviewsit]

I noticed my ears were not ringing this year after shooting during deer hunting because of a can which I will take as a win. Also, the other people in my hunting party didn't hear my shots.This was using a 11.5 5.56

[@basherboy2977]

Does the lightsaber glow effect under NV of the Flow 556k give you enough pause to not buy again? That can is probably top of my list right now.

[@BrassFacts]

no. But it does mean I probably won't buy a second one. I want my other rifle to have a large double walled can

[@coreyperez13]

Always good content. I'm happy with the performance of my Sandman L and my RC2. I use my Sandman L on 30 Cal's (and have a 556 end cap if I stray), with the 300BO Subs, it is amazingly quiet.

[@Merril_39]

One thing ive been trying to figure out. Is it better to put a full size can on an 11.5 or put a K can on an 18 inch? Or is it the only winning combo a full size rifle with a non k can?

[@evanacey1414]

Ammo selection has as much to do with flash suppression as the suppressor itself, if not more so. I keep my 12.5” middy loaded with Hornady’s Black 75 gr Interlock HD SBR load, and with a Sandman K & 556 flash hider end cap I get ZERO flash after the 1st round at night.

[@METALLIFY16]

There really isn’t any downsides of using a suppressor though. Sure it adds weight but like… workout. You shouldn’t only be good at shooting, fitness is important. It’s easier on your ears shooting suppressed, makes communication with teammates easier, masks your signature more, the list goes on.

[@meanman6992]

Something for people who intend to build an AR for suppressor use as in leave the can mounted on that rifle, forever, should consider IMO. Is ordering a barrel WITHOUT a gas port drilled, then have a competent gun smith bore the gas port UNDER sized. Just my two cents, it’s. It hard to increase an undersized gas ports size, hard to make it smaller though…. Though there is a couple companies who offer non adjustable solutions there where it’s effectively a captured bushing between the gas port and gas block that restricts the gas ports diameter. Just thought I’d put that out there as no one likes gas to the face.

[@Enjoyer.762]

Until you need to run it unsuppressed, now you might have to deal with short stroking.

[@scottzagger]

Why would you use it unsuppressed? That would be silly.

[@aktideracer8710]

I’m going to have to get one soon, do a lot of hunting up here in AK and my ears have payed the price, actually building a 6 ARC for coyote/wolf/deer and plan on running a direct thread can on it

[@tylerfrogley1227]

thank you for acknowledging the suppressor use with supers

[@jnichols959]

How much does the muzzle device used to mount the can affect flash suppression? Some muzzle devices are described as providing a "sacrificial baffle" before the can itself, and some are obviously designed to hide flash when used without a can.

[@ToastbackWhale]

Depends a looooot on the design of the can. A recent Jay Situation Podcast episode talked about this.

[@marcondespaulo]

Garand Thumb made a quite long video on "being shot". Quite interesting and adds a different perspective

[@mrfunswitch]

thanks alot for this amazing video. I got a question regarding NV glow. if you put a very good cover on the can, like a libertys defense straightjacket for example, will the cover itself start glowing after 3-4 mags or is this only the case with the can itself because it's made out of metal?

[@BrassFacts]

it will hide it 100% Or at least enough to not matter. But you run into issues where the shroud keeps the can hot, and begins to melt and such. A issue when these things cost 100 bucks per. I keep one on hand for exactly that but I don't typically run it. More of a emergency thing

[@tylerhall6455]

Love the video! Great job on those down range signature comparisons. Unfortunately yea you called it, still confused on what first suppressor I should buy lol. I tell yea I would have already bought one, because usually im OCD on research and can definitively narrow down the "best" or "best for money" of anything. Suppressors I still have no clue. I was for a few weeks leaning toward the oss flow ti, but shit, will the signature be bad? Was told they just have to burn off for a couple hundred rounds then their fine. Just want a 308 can to start, for a dedicated dmr, then a dedicated 5.56 on a 11.5" Ar.

[@BrassFacts]

get a duty sized can, with a good QD system, that isn't monocore.

[@jonathanrogers9961]

I have been able to shoot a SBR with 2 different uppers and the same suppressor. A 8in 300blk, and a 11.5in 5.56 with a silencerco omega 300. My experience, both were surprisingly quiet. The suppressor is longer than I would personally want. and it fouls the guns insanely quickly to an unreasonable level. I would like to get a suppressor and sbr some day. It will be some kind of flow through or reduced back pressure system, as i want to reduce the excessive fouling as much as possible.

[@Hiraeth91537]

Are flash cans/forward blast diverters/jacketed muzzle brakes/linear compensators (whatever you want to call them) actually worth a damn for medium to long range signature reduction (at least, to your sides and back) if you live in a jurisdiction where you can't get suppressors? Or is it better to just stick with a flash hider?

[@DD-hz3ts]

It ONLY exists to somewhat reduce blast to you as the shooter. It actually enhances the flash and increases how far the sound travels to those in front of you. If you cannot own a suppressor but can buy other devices, get the EFAB, it's the best non suppressor device you can buy.

[@ivaniuk123]

When I first got into suppressors I went with the full size because I was chasing decibels. As I got older and fatter I realized that I don't want my rifle to be as long as a musket and shooting supersonic the rounds are still pretty loud so I switched to the k can. I don't know which version of the sig can the army adopted for the sig spear but if it's not the k can then I believe they made a mistake.
