The Whisperstrike Lifesaver 22 suppressor is a lightweight titanium rimfire can that is rated for far more than .22 LR. A serviceable 3D-printed titanium monocore threads directly to the barrel on 1/2×28 while the outer tube floats concentrically around it, which keeps alignment true. Because the suppressor opens up, you can clean it after high-volume sessions instead of living with a sealed can. Whisperstrike lists sound reduction of up to 30 dB. It suits pistols and precision rimfire rifles, and it handles 5.7×28 and .22 Creedmoor hosts as well.

Key Specifications

• Construction is Ti64V ELI Grade 23 titanium with a 3D-printed monocore, giving corrosion resistance without extra weight.
• The finish is Cerakote C-Series, a durable coating for the titanium tube.
• Length is 6 inches, compact enough for pistols and short barrels.
• Weight is 5.44 ounces, light enough for a rimfire rifle or pistol.
• Mounting is a 1/2×28 direct thread, the common pitch on rimfire and small centerfire barrels.
