CRC 3SF002-MIL | WBP | Minizhaba, M14x1 LH, 556/545

CRC 3SF002-MIL | Minizhaba — a subcompact sound moderator/flash hider with M14x1 LH thread, chambered for 5.56 mm (WBP). Designed as a gas-vented unit to preserve semi/fully-automatic cycling without requiring modifications to the host weapon’s gas system. Does not increase mechanical fouling. Compact and lightweight to retain operator mobility.
Compatibility
 
 
WBP Jack — calibers .223 Rem / 5.45×39 mm
 
 
WBP Midi Jack — calibers .223 Rem / 5.45×39 mm

Important:
This device can be used on the CZ BREN 2 if compactness and low weight are prioritized over maximum flash suppression. The model optimized for effective performance on the BREN 2 is 3SF003 Hypnozhaba.
Not for M4/AR platforms. Check your weapon’s barrel thread before ordering.


Trial units available — details at the link.


Design & Function
The unit uses a proprietary gas-vented sound-moderator architecture that routes gas to external passages to suppress flash and disperse sound. Metal additive manufacturing (3D printing) enables internal geometries not achievable with conventional machining.
Operates with automatic fire.
Compatible with night-vision devices.


Important: the recommended barrel length for proper operation is 12" (31 cm) or longer. For effective performance on shorter barrels, choose the CRC 3SF003 Hypnozhaba.


Material & Thermal Properties
Manufactured from Inconel 718, a high-temperature nickel-chromium superalloy used in aerospace applications. The combination of material and internal geometry promotes rapid heat transfer and faster cooldown compared with many alternatives.
