SOme of the space marine scouts look like they have silencers on their pistols. Also the scout sniper rifles are silenced iirc.

Look at a laser rangefinder. The light is outside of the visible spectrum--unless there's smoke or just the right conditions.


What I'm trying to convey is that the flash supressor on a rifle redirects the light from the explosion of the gunpowder in other directions than outward.
A las-rifle, on the other hand, has no excess flash because as a laser, the light is focused together.

I'm well aware of how a flash suppressor works, thanks.

The point I'm conveying is that just because it's a laser weapon does not mean that it will be in the visible spectrum, nor that it will be a single continuous beam.

The 'beams' described in the various Guard novels are also noted as being the afterimages of the bolts, implying that they travel much like a bullet rather than a single coherent beam of light(like the Covenant in Halo's "Focus Rifle"). That also, in turn, implies that you could feasibly suppress the flash from the rifle going off.


The bolt itself makes light, but where has it ever been described that the barrel does when fired?


The bolt does not make light. The bolt superheating the air surrounding it is what creates the light and afterimages.

It's the same effect that you'd have to worry about with railguns and other mass driver weaponry. The friction of the projectile superheats the air and creates an afterimage, but you could feasibly muffle that effect by having a barrel that effectively 'devours' the excess heat when fired.

The pistols do not have 'silencers'. Those are just the normal bolt pistols that they've had Scouts using for awhile.

The 'scout sniper rifles' also are naturally silenced, since they're Needle Rifles.

I have read both, and I don't remember gas being mentioned(btb, they're both produced by BL, too, NOT the main GW studio).

Either way, the actual studio books(the rulebooks and Codex) both state that it emits a beam of focused light, NOT a plasma bolt.

3rd edition rulebook: Laser weapons emit a highly focused beam of light. The short duration high energy beam produces such a rapid temperature change on the target's surface that it vaporises in a small explosion.

Lasguns fire with a searing flash of light and the distinctive snap or crack of ionised air, each pull of the trigger firing a single shot.

Rechargeable power packs feed the discharge generator. Power packs usually possess a highly efficient liquid metal core and vary from small internal packs for lasguns and pistols, to crate sized for lascannons and larger las weapons. Most light power packs provide forty shots, compared to the lascannon packs which are good for only one shot. Las weapons can be overpowered with "Hotshot" power packs, providing more power but less shots. Hotshot packs cannot easily be recharged and the extra stress put on the barrel requires much more maintenance. Power packs can be easily recharged by exposing them to heat, or sunlight through solar converters. In an emergency a pack can be placed in a fire and quickly recharged, although this method shortens the life of the pack and can destroy it altogether.

Guys, I think you're all forgetting one key thing about 40k:

This is a universe where huge armies in giant fleets of ships travel across the galaxy so that they can travel down to a planet and attack each other with chainsaws. There's no need for silencers because there's no need for stealth. Everyone gets full battlefield tactical information from their orbiting ships, so there's no way to hide. And, you wouldn't want to hide. The only reason the battle on the ground matters is for purely entertainment purposes.

It's the same reason that most armies paint themselves bright colors. They want to be visible for the TV cameras.

the supressor increaces the amount of friction on the progectile as it leaves the bareel and enters the supressor slowing the progectile down reducing its range thats why surpressors get so hot so quickly

Believeland, OH

Could you really silence or suppress a bolt? The silencer works by slowing a projectile down to subsonic speed while muzzle flash is handled by a shroud. But bolts accelerate AFTER they leave the barrel by igniting their main propellant and I would Imagine going supersonic. So it would stand to reason that once the main propellant charge goes off after the bolt has left the barrel that you would then have a possible visible sign of ignition followed by most likely a supersonic crack.

It follows the description of bolters being quite loud and noisy (why orks used to love them before GW switched them to Shootas). Each time you fire a bolt you should get two loud cracks, one from the ejection charge produced in the barrel and one from the main charge after it leaves the barrel. Quite a racket when firing three round bursts or full auto.

I don't see anyway to hide that, much like the (what is it in this edition) 10 foot tall 800 pound armored monstrosity that is toting it. One handed mind you. I've always wondered what the marines would use for clandestine missions. Even scouts don't seam the inconspicuous when you think of their size and weight. I mean the British used Gurkhas for a reason. Scouts have to weigh 600 pounds and are at least 7 feet tall in armor. You are not sneaking past anyone. You can forget things like climbing of tree branches unless you can find one to support the weight. They would be defeated by rickety rope bridges.

No, they don't. They slow the bullet down as a side effect of it scraping against the inside of the silencer, and it slightly lowers the sound by muffling the expanding gas. There are subsonic rounds used with silencers, some of which can even leave the shot quieter than the action of the gun, but those are pretty rare simply because of the problems such low muzzle velocities cause.

Probably more of a hiss or roar, like a rocket.

The bolt shell in a silenced bolter is different from standard ones...
From what i have read about lasguns they make a cracking sound when they fire which is apparently the gas being released when they fire (not entirely sure how they work to be honest) a silenced lasgun would presumably have some kind of gas-suppression-system or something...

For silencers to really work you must fire sub-sonic ammo out of them. I mean you can fire ammo that is over sonic speeds, but it wears and tears the silencer a ton.

Eye of Terra.

I guess I don't have a handle on how bolters really work.

When I was in the military, I had a suppressed side arm that we called a 'hush puppy' that fired ammunition with such a low charge that it was subsonic. It fired with a definate 'pop', but you could still hear the 'slide' over the noise. Anything that would break the sound barrier is going to be louder than that.

Now, to silence a LASER I have no idea. A weapon grade laser would generate tremendous amounts of heat along the length of its beam. It is this heat that causes deformation in the atmosphere which in turn creates sound. This deformation occurs along the entire length of the beam. So how this would be silenced I have no idea.

Maybe the laser weapon in 40k isn't really a Laser at all? Maybe this is just a generic 'laymans' term for the weapon?

The Dark Heresy Core Rulebook talks about silencers for autoguns and snub pistols, so they ARE used. However, if you REALLY want to be silent, you have needle pistols and needle rifles. I guess silenced autoguns fill a very small gap between "sophisticatedly silent and deadly" and "military-grade 180dB firepower" for people how can't afford the needle stuff.

PS: Or for someone who is up against armored enemies, since needlers are crap against armor. Silenced autogun with man-stopper bullets is quite a potent weapon in the Dark Heresy ruleset.


Correct. Silencers in Dark Heresy aren't perfectly silent of course, bnut they're arguably better than the ones we have. They're pretty much standard equipment for most DH groups.

Silencers don't work on bolt pistols, however, due to the multistage nature of the weapon-- the rocket stage is damned loud. You need special ammunition for boltguns to become silenced.

That depends on if it's caseless or not. I think it's a bit more advanced than autogun technology obviously.

OP. You know what, you could write an entire dissertation on this subject. This question is too vague! Do you mean silencers, suppressors, or flash guards. There are so many different weapons in 40K, which ones are you interested in, bolt, ballistic,melta, plasma, shuriken,,,etc.

I can provide you with a complete explanation for it all if you want, all it takes is knowledge of the 40K universe and knowledge of how weapons work, I have both.....it will take a half page at least. Can you define your question better? Is there something specific you are looking for or do you want the entire shpeel?

No, they don't. They slow the bullet down as a side effect of it scraping against the inside of the silencer, and it slightly lowers the sound by muffling the expanding gas. There are subsonic rounds used with silencers, some of which can even leave the shot quieter than the action of the gun, but those are pretty rare simply because of the problems such low muzzle velocities cause.


It depends on what you are talking about. silencer, suppressor or flash guard. For a ballistic weapon that to be silent it must do two things.
1 Reduce ignition report.
2 Reduce speed of projectile to subsonic, as a supersonic ballistic projectile creates a sonic boom which will make lots of noise. Hence sonic boom.

Problem: most guns fitted with a suppressor still produce the sonic boom from the round breaking the sound barrier, they only muffle the explosion of the propellant. As a result, "silenced" guns are still extremely loud, just not as loud as an unsilenced one. The frequent ban on silencers stems more from the fact that a silenced shot no longer sounds like a gun shot, and general public ignorance on how big an effect silencers have.

For a shot to be subsonic it has to use specially designed ammo or reduce the pressure in the barrel, which with a sufficiently small round and a silencer can produce a shot that's quieter than the action of the gun, but is generally still over 100 decibels.

Sorry, I thought it would be easy to answer but the more I wrote, the more I realized definitions have to be defined and weapon types are so different. I mean really you could write pages. So instead of just throwing it out there with incomplete info I thought I would ask if there was something specific. As it appears there is not even a general consensus, here at least about what a suppressor, silencer or flash guard do and how they would affect each weapon. REALLY DIFFERENTLY is the answer.

I think suppressors and silencers and flash guards are very different objects and fulfill separate rolls. But after some research America and England have different definitions (Truck/Lorry, Rubber/Eraser) of the two pieces and some believe it synonymous.

I didn't want to impose a definition yet without more research. So I asked for a better question.

@Platuan4th- Ah, sorry I missed that somehow Platuan4th. I try and make sure I read every post in the thread before I respond on most occassions so I don't repeat unneccessarily.



Still, I don't think you can silence a laser. Silencer is an archaic term in the military at least something to be heard in an old "James Bond" movie, lol. We called them supressors, most were 'tunable' as well.

As to the supressors on GW's figures they must have some function or they wouldn't be there. They are figures representative of 40k fluff and fluff trumps all logic.

Lasguns can't be silenced outside of fighting in a vacuum. The crack of instantly superheated air and all that.
