The Bersa B22 rimfire suppressor (Bersa part no. BS-10001) is a modular, hard-use can built from 6AL-4V titanium and 17-4 stainless steel with a high-temperature Cerakote finish. Without tools, it switches in seconds between a compact 3.41-inch, 4.5-ounce setup and a full-size 5.8-inch, 6.4-ounce setup for maximum sound reduction. Bersa rates it for .22 LR, .22 WMR, .17 HMR, .17 WSM and 5.7×28, and for full-auto use with .22 LR. A replaceable thread adapter system fits a wide range of host muzzle threads, and the titanium baffle stack cleans with solvent or an ultrasonic cleaner. It suits a shooter who wants one durable can for rimfire rifles, pistols and 5.7×28 hosts.
