The Thunder Beast Silencer Summit fires every suppressor entered on the same gun, on the same day, with the same equipment. Atom22-Lite was measured in 1 test. Figures can only be compared with others from the same test, so each one links to everything else fired on that gun.

Manufacturer claim
- Full-auto rated for .22 LR only. Echo Zulu Defense advises against rapid-fire sessions with .22 WMR or .17 HMR and says suppressor temperature should stay below 900F to preserve the titanium construction.
- A 3.5-inch rimfire suppressor built by Direct Metal Laser Sintering with a conical clipped baffle stack, which the company says optimizes sound suppression and delivers low first-round pop with a smooth tone.
- Titanium construction finished in High-Temp Cerakote, a ceramic-based coating the company says withstands the heat of high-volume rimfire shooting while resisting corrosion, solvents and scratching.
- Sealed and non-disassemblable, which the company says means no baffles to misalign and no end caps to lose; cleaning is by soaking or ultrasonic cleaner with no tools required.
