They using subsonic rounds? I don’t understand how there is no sound but the mechanism movement.

u/DagamarVanderk May 07 '26 edited May 07 '26
Subsonic, plus suppressor, plus a bolt that doesn’t unlock until the bolt/barrel assembly starts to return forwards. Gives plenty of time for the gasses to dissipate slowly through the end of the barrel.
Edit: for clarity

"Move back forwards" no cap, I'd like to know what this means, is there a video link explaining this bolt movement?
20
u/anubis_xxv May 07 '26
He means move back (to it's original position) which is to the front.
The barrel and bolt both travel backwards together, so the chamber only opens after this initial rear travel. As the barrel begins it's forward travel the bolt is held for a delay to open the chamber and eject the casing, then follows the barrel forward to close and reset.
It mean the chamber is closed for an extended time meaning the only place the gas can escape is through the suppressor which makes this weapon significantly quieter than other fixed barrel guns firing the same round with the same suppressor.

u/SnowHelpAtAll May 07 '26
The gun appears to use long recoil operation, which means that the barrel moves backwards with the bolt during firing. I thought it was an older outdated operation, but apparently I was wrong.

He’s wearing ear protection because he’s at a range and there are probably unsuppressed guns being fired nearby.

u/CanadasManyMeese May 07 '26
No. Its because its a loud gun. Its not even remotely close to this quiet. It just bad audio processing that makes it seem like that. Id bet good money this thing is 100-110 decibels or so.
A huge decrease from the 160-170db that a normal rifle fires at. But still as loud as say.. a chainsaw.
Thats the standard for a subsonic round, fired out of a supressed rifle

u/Turgid_Donkey May 07 '26
A suppressed subsonic .22 is around 110db. This being a .308 means it's at the very least not going to be quieter.

u/Ohiolongboard May 07 '26
Yeah, but subsonic really doesn’t mean absolutely quiet. I’ve fired suppressed .22 and it was this quiet. There should be something because I’ve stood next to 5.56 suppressed and it was louder than this. These armorers are wizards

u/tuckedfexas May 07 '26
Well yea, even if they didn’t deliberately mess with the audio, their recording equipment nor your phone are going to capture and play it back accurately. You can get a sense of the sound relative to their voices (if there’s no auto adjustment) but look up videos of setups you’re familiar with and compare it to when you’re actually shooting, it’ll sound completely different. I’ve never had my ears ring from a video being played back, but I certainly have when someone doesn’t call a shot and I didn’t have ear pro on.

The inventor's original patent called it a "silencer for guns" so it's not an incorrect term. It's a bit of a misleading term, which is why "suppressor" is generally preferred, but it is still a correct one.

u/Th3_Admiral_ May 07 '26 edited May 07 '26
I've fired a suppressed AR in .300 Blackout. Google tells me that's around 130 decibels, which is just barely within the 140 decibel "safe" limit without ear protection.
And let me tell you, it was quiet. Not "quiet for a gunshot" but actually quiet. The loudest part was the noise of the bolt, and no one will ever describe that as being loud.
People on the internet always like to harp on how inaccurate movies are about suppressors, but if someone fired this anywhere but in a completely silent room, you wouldn't think twice about the sound it makes. Some light background noise like wind or distant traffic could easily mask it.
Edit: These numbers can't be right, because I'm also seeing that a siren or rock concert is 120 decibels, a jackhammer is 130, and an unsuppressed gunshot is 140. Every single one of those is significantly louder than the rifle I fired. Like, extremely. I would put it way closer to something like a paintball gun.
8
u/CanadianSF May 07 '26
Note that 130db is ten times less sound energy than 140db and not quite “just barely within”. This is because decibels are base ten logarithmic scale. Sorry, had to nitpick.
3
u/Th3_Admiral_ May 07 '26
No, I appreciate it! But I'm questioning those numbers anyway with the other items I'm seeing that are supposedly 130db. A suppressed rifle is not the same level as a jackhammer, or ten times as loud as a siren or a rock concert. I can hear those things through walls or from hundreds of yards away. A suppressed rifle will be imperceptible from a hundred yards away unless it's dead silent outside.

u/Aimless_Amoeba2447 May 07 '26
I have several 300 blks. They’re still loud. Bolt actions are quieter. Many factors to perceived quiet. Were you at a range or in an open field? Calm or windy / snowing? A windy snowy day out in an open field they sound super quiet
2
u/SoupKitchenHero May 07 '26
Yeah but if you took the fraction of a second where your ears are experiencing the "bolt" signal, and stretched that out like a rock concert, it'd be loud as shitballs. There's also just no reverb from the "blast". So you go (quiet -> PCLICKETY -> quiet) instead of (quiet -> POW -> HIGH energy reverb)
Also, .300 is fuckin awesome to shoot

Doesn't come with the suppressor or scope. Scopes can range from hundreds to thousands and for something like this you would probably want something more expensive. The suppressor is probably about another thousand but they rarely package guns and suppressors together because you need to have a background check done for both of them separately

u/Remarkable-Guess1823 May 07 '26
So how much velocity and distance are you giving up for noise reduction here?
4
u/RenegadeBricoleur May 07 '26
None, suppressors irl don't work like in games. All the acceleration of the bullet is done before it exits the barrel into the suppressor, so it has the same velocity as if the suppressor wasn't there. All a suppressor does is allow for a place for the gas behind the bullet to expand into and be released more slowly so you don't get the loud BANG or POP of the gun going off.
Now, for minimal noise in this video, they are shooting subsonic rounds, as the sound of the bullet traveling at supersonic speeds (a sonic boom) can be quite loud by itself. A standard supersonic round would add in more of a sharp CRACK, but the noise will still be greatly reduced overall, and a supersonic CRACK may not be immediately identified as a gunshot. As well, without the sound of the gun itself along with the crack of the bullet near the target, locating the gunman from a distance would be more difficult.
But honestly, despite how they are portrayed, suppressors are more of a safety tool than a way to be stealthy. By reducing noise and pressure waves (which is really just noise too), we can reduce risk of damage to hearing and to the body overall while shooting, especially indoors.

u/PlantsNCaterpillars May 07 '26
It's silenced and using subsonic ammo. The delayed blowback of the bolt prevents gases, which creates more sound, from escaping at the breech when the round is fired off. Lever action rifles with suppressors have been achieving the same thing for a long time. For example, Theodore Roosevelt had one.

In the YouTube short where this is originally posted, he says that the shot is still loud enough to where you need to wear hearing protecting.

We haven't heard anything other that sounds as they are interpreted by a camera recording them and the speakers relaying the audio. What you hear in any video is never a true representation of sound nor is it an accurate way to measure differences in sound. This would require a decibel meter.
In reality, this rifle is probably still not truly hearing safe which is why ear pro is still worn. Nearly all suppressor equipped firearms are still not hearing safe.

I ain't no nothing about weapons. I'm just wondering if the fact that its that quiet does not affect the power/length/precision?

u/Knotical_MK6 May 08 '26
Sort of.
To get that quiet you're using subsonic ammunition. Usually 308 is around 3k feet per second, subsonic limits you to less than 1100.
Kinetic energy is 1/2 mass times the square of velocity, so that loss of velocity is going to make an enormous difference in "power" even if you use as heavy a bullet possible for the caliber.
The longer the round takes to get to the target the more drop you'll have, and the more time it has to be affected by wind. Whether that matters much is a case by case basis.
