So my understanding is that an integral suppressor is basicly a ported barrel that is ported the whole length and has the ports covered up by a suppressor. When fired bullet travels down the barrel dumping sound waves into each baffle as it passes them then exits. Would it be possiable to subtract one baffle from the end, thread the barrel, and attach a second suppressor onto it? AE instead of 16 inches of supressor you would have 15 first +8 second, giving a MUCH quieter report? Would the shooter essentially have 2, 30 DB reductions of report and have around 80 total sound(loud conversation)? (cuz Im thinking about doing this if it would work.)

I think you're oversimplifying the physics.

If there is a reason you havent seen it before, u answered your question.

Integrals come in all types of designs. What you outline above is one example. What you propose is usually done as a one piece design like MP5SD without extra threading.


ETA:

Sound reduction is not linear addition - 4 30db cans in a row does not yield 120db reduction.

Unless it is a subsonic projectile it doesn't really matter at all anyway.

Pick up a copy of Al Paulson's books on Suppressors. While the suppressors discussed inside are way out of date the technical aspects about sound are not.

Exactly. There's only so much you can do to reduce the expanding gasses and still move a bullet down the barrel at a reasonable FPS. You can't just make a can twice as big to double the sound reduction. You meet a point of diminishing returns, which is pretty close to what is on the market today, and the reason you don't see an integrally silenced barrel with a thread on silencer at the end.

Another thing to keep in mind is that it's a 2 stamp gun at that point. Why would someone want to pay $200 more dollars to add a second suppressor when you could just make the first, integral suppressor, much more effective?

Good question, I had wondered the same thing myself.

Not even close to true, unless you do not think 30db reduction doesn't matter.

And most integral BBLs, which is what OP is talking about, prevent supersonic flight, especially the highly ported design the OP mentioned.

I'll assume you mean the reduction you get with full power loads - of course it matters but it'll never be "quiet"....

and I understand this....

the video shows the difference between the two.... as unscientifically as I could get it.

AAC Honey Badger uses two suppressors, an integral and a detachable.

Depends upon your definition of quiet.

When I fire 5.56/7.62 rounds suppressed in my backyard, nobody in my house hears a thing. I fire them without suppressor, they and anyone within a mile or so, hears everything.

Some good points have already been made.


Needless to say, I'll add that a thread at the end of an integrally suppressed barrel is a good thing. You could use a flash hider in conjunction much like the appeal of the Saker.
