principles
A suppressor is a chain: each baffle takes part of the blast and hands less to the next. We design the chain, not the tube.
How we designTesting
Measured,
then published
Sound numbers go online with the method, the ammo, the rifle and the barrel length, or they don't go online.
How we testMaterials

accounted for
Stainless where the gas hits hard, aluminum where it doesn't. The cheapest metal that does each job.

Why we named it Protonic
A suppressor company named after a subatomic particle. Here's the reasoning, and why it isn't a gimmick.

Numbers, not adjectives
Suppressor marketing is full of "whisper quiet." We're going to publish dB with the method behind it, or nothing at all.

Four cans, each named for the job it does. Here's how to tell which one you need.
ReadAbout Protonic Precision
Stable under pressure.
Protonic Precision is two brothers making suppressors from first principles. The name comes from the proton, from the Greek prōtos, "first." Protons push apart with enormous force, the strongest force in nature holds them together anyway, and no one has ever seen one fail.
That's the whole job of a suppressor: hold violent energy in a small space, shot after shot, without breaking. Cans come first. A rifle line designed around them comes next.
What we make
Four suppressors from .22 rimfire to .45-70, the Gluon and Pion mounts that hold them on, and, coming soon, rifles built suppressor-first. Each part of the system is designed to work with the rest.
How we work
Physics is the story; specs sell the product. We publish measured numbers with the method behind them, and we don't publish anything we haven't measured.
Who we are
Two brothers. Like a proton, most of what holds us together is the bond, not the parts.

Frequently asked
Buying, owning and running a suppressor, and what we make.
01What is Protonic Precision?
Two brothers making suppressors from first principles. Four cans, from .22 rimfire to .45-70, each named for the job it does. A rifle line, LINAC, is coming soon.
02Where can I buy one?
Through any licensed suppressor dealer (FFL/SOT) in your state. Black is sold out in every size right now, and Desert Sand and Grey are coming soon. Get a restock alert and we'll tell you the moment they're back.
03Why "Protonic"?
The proton is named from the Greek prōtos, "first." Protons are held together by the strongest force in nature, and no one has ever seen one decay. That's the job description of a suppressor: contain violent energy in a small space, shot after shot, without failing. The full story.
04Which can do I need?
Each can is named for the job it does. Proton Plinker is for .22 and .17 rimfire. Proton Sidearm is for 9mm pistols and carbines. Proton Adapt is the rifle can, from an AR-15 to a .300 Win Mag. Proton Safari takes the big ones: .45 ACP, 10mm and big-bore rifles like the .45-70.
05Do I still need a tax stamp or Form 4?
It depends on your state, and it changed recently. As of 15 Oct 2026:
- The federal NFA tax on suppressors has been $0 since 1 January 2026.
- Since 9 October 2026, after Silencer Shop Foundation v. ATF, ATF says it is not enforcing NFA registration, Form 4 approval or tax-stamp rules for suppressors. ATF also says that position can change.
- Federal law still requires buying from a licensed dealer in your state, with a background check (Form 4473).
- About fifteen states still require a Form 4 under state law.
Read ATF's current guidance and our buying guide, and ask your dealer what applies where you live.
06Can you ship a suppressor to my house?
No. Federal law doesn't allow it. Suppressors ship to a licensed dealer in your state, and you pick yours up there after the background check. Mounts, apparel and swag can ship to you directly.
07Are suppressors legal in my state?
In most states, yes. Civilians can't own them in California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, Rhode Island or Washington, D.C. Hunting with one is also restricted in Connecticut. Laws change, so check a current source such as this state-by-state list, and this one for hunting, before you buy.
