The Whisperstrike Lifesaver 22 Flat Dark Earth suppressor is a lightweight titanium can built for rimfire shooters who also want to run small centerfire cartridges. A 3D-printed titanium monocore threads straight to the barrel while the outer tube floats concentrically around it. That layout keeps the core aligned and lets the suppressor come apart for cleaning. Whisperstrike claims sound reduction of up to 30 dB. This Flat Dark Earth version suits a tan or desert-toned rifle or pistol and works as a single can for a mixed rimfire and 5.56 safe.

Key Specifications

• The caliber rating runs from .22 LR through 5.56 NATO (5.56 on rifle barrels 16 inches or longer), so one can covers rimfire and small centerfire guns.
• Overall length is 6 inches, short enough to keep a rimfire rifle or pistol balanced.
• Weight is 5.44 ounces, light enough that it barely changes how a host gun carries.
• It mounts by 1/2×28 direct thread, the common muzzle thread on rimfire barrels and many 5.56 barrels.
• The finish is Flat Dark Earth Cerakote C-Series over a titanium tube, a coating chosen for durability without added weight.

Do I need ATF approval to buy this? No. As of October 9, 2026, ATF no longer requires Form 4 approval, registration or a tax stamp for suppressors. It transfers on a Form 4473 with a background check through a Class 3 (SOT) dealer. State and local laws still apply.
