The Whisper Pickle 556K from North Reach MFG is a 5.5-inch rifle suppressor rated for .223 Remington, 5.56 NATO, and bores up to 6mm. Built from cold-rolled 300 series stainless steel and finished in FDE Cerakote, it runs a six-baffle stack combining step-radial and 40-degree baffle geometry inside a 1.5-inch diameter, 13-ounce housing. It mounts via 1/2x28 direct thread or the modular Bravo HUB interface, and it's rated for full-auto fire up to 150 rounds continuous.
The Whisper Pickle 556K is machined from cold-rolled 300 series stainless steel, chosen for its corrosion and pitting resistance along with the high-ductility characteristics needed to resist cracking through repeated high-temperature heat cycles. The six-baffle internal stack pairs step-radial and 40-degree baffle geometry in a low-back-pressure layout. The FDE Cerakote finish covers the 1.5-inch diameter, 13-ounce housing.
Mounting is handled through a 1/2x28 direct thread adapter, included with the suppressor, or through the modular Bravo HUB interface using 1-3/8x24 threading present on both ends of the unit. This dual approach allows the suppressor to work with Bravo HUB-pattern mounting accessories in addition to standard direct-thread setups.
North Reach MFG rates the Whisper Pickle 556K for full-auto fire, with a continuous fire rating of up to 150 rounds and no stated barrel length or firing restrictions. Recoil reduction is a stated feature of the design.
The suppressor ships with the 1/2x28 direct thread adapter and a QR-code owner's manual.
Follow all manufacturer instructions and safe handling practices.
Ensure compliance with all applicable federal, state, and local laws.
Verify caliber and mounting-system compatibility before use.
Confirm secure attachment and inspect the suppressor before each use.
