Although it’s heresy to even think it and could get one burned at the stake (or at least on the Internet) in some circles by the self-styled wound ballistics priesthood, that’s a question I first asked myself decades ago.

When reviewing the research published by Marshall and Sanow on how specific handgun cartridges and loads varied in their effectiveness at stopping attacks, I noted that the most effective loads also tended to produce the most muzzle blast. One that comes to mind was the Federal 125 grain 357 Magnum Hi-Shok load (and which I still have an ample supply of). Causation or correlation? Who knows? But a similar psychological principle is involved in the use of flashbangs by SWAT teams and military hostage rescue forces like the British SAS that initiated the practice. They make bright flashes of light and loud noise. The disorientation that causes provides enough of a tactical advantage for bangs to be commonly used despite their disadvantages.

Of course, no sensible person would risk seriously advancing such a notion about firearms effectiveness, so I certainly won’t.

They were damn lucky the ATF never classified that device as a silencer. It is basically a single chamber silencer but is considered a flash hider by the ATF.

This. It’s basically a 1 baffle suppressor if you take one apart.

I can't find good pics online, but it appears the KX3 and KX5, are just flash cans, like this: https://www.kakindustry.com/kak-industry-flash-can
(But since they bear the Noveske name the KX3 & 5 just cost more)

If so, it's just a cone inside a tube, and nothing like a baffle.

Now, this one:

Seems to be more like a "single baffle."

Is Noveske stuff expensive, yes but you’re comparing CM stainless steel to the aluminum construction of the KAK. Does that make it almost four times as expensive? Probably not but I’d rather have steel right there at the exit of all that hot gas.

The testing that they did on a 16" rifle in .223 the aluminum baffles held up fine. They showed some erosion but it was painfully obvious the difference barrel length made. So I'd say you are fine with aluminum on 16"+ barrel.

The aluminum model likely will be OK for the average shooter on a 16" rifle, mainly because the average shooter may only put 1K or 2K rounds down a given AR over the course of their life. For those of us who shoot rifles enough to wear out parts, the steel model will be better.
