You say your .223 suppressor is as follows:

The Mystic-X that I’m waiting on the ATF paperwork to come back on, is 8" long, 10.3 oz, and has an OD of 1 3/8".

There are four factors in play here - length, weight, thickness and overall size (volume). So let's compare them...

Length - yours is the same length as this one.
Weight - yours is 16.5% heavier.
Thickness - yours is 27% larger in diameter.

Volume takes a second to figure, but not overly complicated. It’s (Pi x radius x radius x height)

Volume of your 8” x 1.75” unit = 76.97 cubic inches.
Volume of the Mystic-X at 8” x 1.375” = 47.52 cubic inches.

And 76.97 was a buttload bigger than 47.52 when I went to school. And percentage-wise, it’s a massive buttload bigger; 62%

Volume - yours is 62% bigger.

So in no dimension (length, width, weight, or volume) does yours do better, so that kind of answers everything except the “5-10X” cost aspect. I’m going to assume we’re talking about doing this legally; just building it yourself, so that means the $200 tax stamp cost is unavoidable no matter what else we do, or where else we reduce cost.

My total cost on the Mystic-X was $950, including both the $200 tax stamp and sales tax. One-fifth of that would be $190. One-tenth of that would be $95.

How do you make that math work? Your highest-estimated cost is less than the cost of just the tax stamp alone, so even if there was zero production cost, it still can’t be done at even your highest “one-fifth” claim. The “one-tenth” thing is obviously even further into the realm of the impossible — again, assuming we’re keeping things legal and paying for the mandated tax stamp.

A person can certainly build their own for less than what this one cost me, but they can’t build it for less than one-third the cost, much less one-tenth. And they certainly won’t build a lifetime-warranted one for that.

And the commercially-available one also has a “repair or replace, free of charge” lifetime warranty, which imo is certainly worth something in the equation.

Fwiw, not saying it's a bad idea to make your own or that it can't be done and done cost-effectively. Just saying that there's no way to (legally) do it at one-fifth the cost of a manufactured one, much less one-tenth; and pointing out that "manufactured" doesn't mean "big" or "heavy" either one.

For that matter, for another example - the commercially-available suppressor that I use on my 9mm pistols and camp-9 carbine is right at the same size and weight of what you describe for your .22 suppressor. It's 0.98" by 5.7" long, and weighs only 3.3 ounces; 5.3 oz or so if I go to the trouble of grease-charging the artificial-environment aspect of it.

JMD - you still haven't answered the simple question.

And once again, no answer...

So to recap:

Your math is blatantly wrong. Wrong to degree that should be obvious to a fourth-grader.
Your design is substantially heavier.
Your design is a whopping 62% larger.
Your design has to have its internals rebuilt every few hundred rounds, or any time it’s disassembled for cleaning.
Your design basically sucks by 21st-century standards.


Congratulations. You have the best 1950’s tech, kitchen-table built, short-life-expectancy suppressor design still around.


(Want a hint as to WHY there are no others like it still around…? Think “Mayberry technology”; because most of us have left the 1960’s and 70’s behind us.)

John, can you please stop confusing the issue with facts?

I'd just like to know how to legally get one of these awesome sub-$200 suppressors I read about. Because I'd do it in a heartbeat...
