A flash hider such as a "3 prong" achieves the same affect with no moving parts, also suppressors can pretty much eliminate all flash and offer hearing protection and additional signature reduction by reducing the db levels and changing the pitch of the noise.

Yeah for a fraction of the cost in complexity, weight and issues with consumables a suppressor does all of what they were talking about and more. The US army is in theory going to a new rifle and issuing suppressors to every (frontline) infantry unit with the NGSW contract.

(We'll see how widely the new system and everything actually gets deployed but it was an important part of the whole program at least)

Why not just build one in? I guess I'm accustomed to assault rifles having flash suppressors because the one that I've actually handled and lugged around and shot with, the Valmet RK 62, does have a suppressor built in, a distinctive feature [1].

I'm not seeing anything about a built in sound suppressor just a flash suppressor which is a fairly common feature on modern assault rifles and their civilian variants. You don't generally build in a suppressor because they're technically wear items as the hot gases will slowly erode the baffles over time. That plus their extra weight and cost meant most militaries only issued them to units that were built for stealth missions in the past.

Ah, when you said "suppressor" I thought you meant "flash suppressor" but rereading I realize you meant "sound suppressor" like the GP.

From the Wikipedia article:

> In addition to the flash suppression, the end can quickly cut barbed wire by pushing the muzzle onto a strand of wire and firing a round.

What an interesting feature!

Possibly length is a factor

A bit yeah though they went from 20-inch M16s at the beginning of the GWOT to 14.5 or less as the main weapon so there was space to slap a suppressor on but you'd give up the maneuverability gains of losing that length. The NGSW winner is pretty short barreled before the suppressor is added and it required particularly spicy (high pressure) ammo to still be effective at that short of a length.

I want to compare the modern versions of suppressions with the old designs of one-way-fluidic valves.

The reason:

Davinciy was cabable of documenting the vortices of variues pulses of fluidicsbut the vortices expecticed creates the fluid dynamics

Hopw the fuck in 400 years have these guys come NOT up with better?

I dont trust a single structural eng.

You’re basically describing “muzzle brakes and flash suppressors, but with more components to refill/repair”

Separately, using the force of the round (either via a gas tube or via direct rearward motion) to propel the action of the firearm isn’t really an AK47 thing, it’s common to all semi automatic rifles and predates the AK47 by quite a while.

I know.

"propel the action of the firearm isn’t really an AK47 thing, it’s common to all semi automatic rifles and predates the AK47 by quite a while. "

Kalashnikov invented the easiest way to manufacture this behavior... This is the reason its the most heinous of weapons.

I am talking about something different. And thats OK.

I am talking about a specific method of funneling muzzle output to funnel through your suppression...

I am talkingabout a hydro-enahnaced flash press which does a certain thing. Please talk about what that certain thing is.

The most environmentally way to reduce muzzle flash. Cloud of water vapor as an expulsion of the muzzle such that it interacts with the blast easily enough to expel the right amount of water vapor through the expulsion chamber as the expression continues through the valve, (barrel) and its in-flame-ant mitigated by the entrenchment water vapor cloud to expel the munition, but still keep other perams in check?

Maybe relevant to your idea, if I'm understanding it correctly: you can put water in a suppressor to mitigate first round pop.

AK47 isn’t the first rotating bolt gas piston carbine with muzzle devices with booster effect, it’s just an evolution of Sturmgewehr concept and one of the first generation assault rifle so retroactively categorized.

I’ll skip over lubed suppressor concept as I don’t know more than Google tells us :p

In all honesty, there isnt much room to improve the actions of modern assault rifles. There are dozens of post-stoner improvements that have bern tried. Millions have been spent on them. They have all been shelved as to complex or cumbersome. The gas-operated rotating bolt is so elegant, so reliable, that fundimental improvements are hard to imagine.

Adding water to the equation? Rust, mud, weight, boiling ... you would need some radical improvements to justify such added complexity.

I suspect there should be a lot of room for improvements, just that we are not able to perceive them without first- or second-world war going on.

I remember reading about importance of a newfangled barrel free-floating construction on carbines, soon after the Afghan war started. The examples used at that time were kludgy top-rail secured things supposedly used by mysterious SEALs guys. Later I saw Crane stock for the pair of chemical lights.

Today, those are slim M-LOK with rail on top and secured to the barrel nut, HEL-STARs, and MOE SL stocks. Oh and Russian Army standard infantry rifles are now cheap AKs with f*’ng buffer tubes, and G36 now has short aluminum mounts to avoid floppy carrying handle issues(“polymer degradation” fiasco).

What caused all those changes were clearly the wars.

Those aren't changes to the action, the core of how the rifle functions.

I don't think muzzle flash is a big problem in today's rifles. Any powder left burning by the time the bullet exits the barrel is wasted energy, so things tend to get optimized pretty thoroughly (this is the field of internal and transitional ballistics). Carbine-length firearms (if they're chambered for rifle rounds) do tend to have bigger issues with muzzle flash. Flash suppressors [1], either integrated or add-on, help and have exactly zero complexity compared to a hypothetical water mister.

Muzzle flash is a HUGE problem with modern ar-15 style rifles. You won't get 100% efficiency until something like 22-26 inch barrels, but that's a VERY long gun to be using (and even those have muzzle flash).

With all the urban combat, there's a push toward shorter and maneuverable. In something short like the 10.5" M4A1 CQBR, flash becomes a much bigger problem (especially in dark rooms where it can be positively blinding to the shooter).

A suppressor helps with this issue, but it also starts adding back length to the gun (somewhat defeating the purpose).

300 blackout supposedly helps the problem (I've never shot it from a SBR) and also has better short-range (esp subsonic) ballistics compared to 5.56, but it too has muzzle flash.

The newly selected Army XM5 rifle and cartridge were designed for super-high pressures and achieving high speeds in a short barrel likely causing even more muzzle flash. Thankfully, this rifle is going to be suppressed for everyone by default. Unfortunately, it's super heavy (and that's without the super-heavy optics), has less ammo per magazine, and despite the goal, is still going to be blocked by higher-level body armor, and is still 36" in a SBR configuration (for comparison, the Israeli CTAR-21 is 30% shorter at just 25" providing rifle firepower in a SMG package).

This was what I was talking about, but failed to articulate.

I think TempleOS started in a similar fashion…
