- At the 2025 Thunderbeast Silencer Summit — testing independently conducted by Thunder Beast Arms — the HARMONIX ranked #1 of 22 suppressors at the Shooter's Ear in 9mm in both dB and peak pressure and #2 in dB(A); in 5.56 it placed #5 of 86 at Muzzle Right. All tiers share the same baffle geometry, so the sound results apply across the line.
- The ION is the lightest and least expensive HARMONIX tier ($975); it suppresses identically to the Ti-CONEL and Sentry and is more than durable enough for range, hunting, competition, home defense, and recreational full-auto.
- Uses the Faxon HUB mount interface and ships with a Direct Thread HUB Adapter (1/2x28 for 5.56, 5/8x24 for .30 and .36 Cal); pair with a MuzzLok Plan B compatible muzzle device for quick-detach.
- 6.75″ long and 1.675″ max diameter; full-auto rated across all calibers with no minimum barrel length restriction on semi-auto or bolt-action hosts.

- Made in the USA by Faxon Firearms, an ISO 9001:2015 certified manufacturer headquartered in Greater Cincinnati, OH.
- The ION body and blast baffle are 3D-printed from Grade 5 Titanium for the lightest weight in the line (7.84 oz).
- The .36 Cal bore is the widest, the only HARMONIX bore that handles 8.6 Blackout, 9mm PCC, .350 Legend, and .338 Federal in addition to everything the .30 Cal covers — one can for rifle and pistol-caliber platforms.
- Ships with a 5/8x24 Direct Thread HUB Adapter.
- A larger bore can safely suppress smaller calibers (a .30 Cal bore also suppresses 5.56), but a suppressor must never be used on a cartridge larger than its bore.
