The Whisperstrike Lifesaver 22 OD suppressor is the olive drab version of a compact titanium rimfire can that is rated well beyond .22 LR. It is 6 inches long, 1 inch in diameter and weighs 5.44 ounces. Whisperstrike uses a symmetrical gas distribution design to control gas evenly through the core and reduce point-of-impact shift. The 1/2×28 direct-thread mount fits the barrels most rimfire and small centerfire shooters already own. Choose it when you want a serviceable suppressor in a muted field color for a hunting or training rifle.

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 olive drab (maker color OD Green) Cerakote C-Series Cerakote C-Series over a titanium tube, a coating chosen for durability without added weight.

Frequently Asked Questions

How does it attach to the host gun? It threads directly onto a 1/2×28 muzzle, and the monocore locks the suppressor in line with the bore.

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.

Can I take it apart for cleaning? Yes. The titanium monocore is fully serviceable, so the suppressor opens up for cleaning instead of being sealed like most rimfire cans.
