The Whisperstrike Trophy 556 DT 5.56 suppressor in tungsten is a titanium can that pairs a gray Cerakote finish with a simple direct-thread mount. It weighs 8.2 ounces, measures 7 inches long and threads onto a 1/2×28 muzzle without a separate adapter. Whisperstrike builds it for hunting and general-purpose rifle use and rates it for full-auto fire, with sound reduction listed at up to 30 dB. It is a straightforward choice for a shooter who wants a light 5.56 can that also handles .22-250 and .22 Creedmoor.

Key Specifications

• The caliber range is 5.56, .22-250 and .22 Creedmoor, so the same can covers the AR round and two popular varmint and hunting chamberings.
• The mount is a 1/2×28 direct thread, which threads straight onto a standard AR-15 muzzle with no separate adapter to carry.
• Weight is 8.2 ounces, light enough that it barely changes the balance of a hunting rifle.
• Overall length is 7 inches, compact enough to keep a rifle handy in the field.
• Body diameter is 1.5 inches, the figure to check against handguard and optic clearance.
