The Bersa WhisperTech .22 LR suppressor (Bersa part no. WTB-22) is the rimfire member of Bersa’s WhisperTech line. WhisperTech is Bersa’s suppressor line built on the patented Couvillion solids-separation method rather than a traditional Maxim baffle stack, which Bersa says allows smaller, lighter cans with minimal blowback, reduced muzzle flip and minimal point-of-impact shift. Separating solids from the gas flow is a sensible approach on a .22, where unburned powder and lead are what foul a rimfire can. The line is user-serviceable, and Bersa notes improved attenuation at the shooter’s ear. It suits a rimfire rifle or pistol shooter who wants a quieter, cleaner-running .22.
