The Whisperstrike Lifesaver 22 FDE suppressor pairs a flat dark earth Cerakote finish with a design aimed at the shooter who wants a rimfire can that can handle more. Inside the tube is a serviceable 3D-printed titanium monocore that threads directly to the barrel for alignment. Whisperstrike builds it from Ti64V titanium and rates it from .22 LR up through 5.56 NATO on rifles with barrels of 16 inches or longer. At 5.44 ounces it is light enough for pistols and precision .22 rifles alike. It uses an advanced gas-flow design to keep backpressure low and cut carbon buildup.
