Why Choose the Faxon MuzzLok® Mini Plan B Flash Hider?

Designed for shooters seeking a shorter, more compact flash hider that still provides excellent flash signature reduction and the repeatable, secure timing of the MuzzLok® Plan B system. Ideal for precision rifles and larger calibers where minimized length and weight are priorities while maintaining HUB-mount compatibility.

• Effective flash reduction: Classic design significantly cuts visible muzzle flash at typical engagement distances.
• Compact & lightweight: Mini profile reduces overall length and front-end weight compared to full-size models.
• Repeatable timing: Left-hand MuzzLok® nut allows precise port orientation and consistent reinstallation.
• Durable construction: 17-4 PH stainless steel with nitride finish resists corrosion and withstands repeated mounting cycles.
• HUB-mount ready: Pairs seamlessly with Plan B → HUB adapters for use with 1.375-24 HUB suppressors (such as Faxon HARMONIX® & CORESYNC® when configured appropriately).

Quick Installation Summary

Always follow safe firearms handling practices. Ensure the firearm is unloaded before installation.

1. Thread the flash hider and timing nut fully onto the barrel until they contact the shoulder.
2. Back off and rotate until ports are roughly in the desired orientation, then back the device ~10–20° from final timing.
3. Hold the flash hider in place and bring the left-hand timing nut up against the barrel shoulder to lock timing.
4. Using a wrench on the flats, rotate the flash hider forward into final timing and torque per the instruction card. Verify timing and POI after installation.
5. If pairing with a Plan B → HUB adapter for hub-mount use, install the adapter before attaching the suppressor.
