Compact flash suppression with repeatable Plan B timing and rugged stainless construction.

- Finish: Nitride

- Origin: Designed and manufactured in the USA by Faxon Firearms
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 PCCs, pistols, and AR platforms chambered in 9mm where minimized length and weight are priorities while maintaining HUB-mount compatibility.
Performance & Benefits
- 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.
- Thread the flash hider and timing nut fully onto the barrel until they contact the shoulder.
- Back off and rotate until ports are roughly in the desired orientation, then back the device ~10–20° from final timing.
- Hold the flash hider in place and bring the left-hand timing nut up against the barrel shoulder to lock timing.
- 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.
- If pairing with a Plan B → HUB adapter for hub-mount use, install the adapter before attaching the suppressor.
