Why Choose the Faxon MuzzLok® Mini Plan B Muzzle Brake?

Engineered for shooters who want a compact, high-performance muzzle brake with excellent recoil mitigation and the repeatable, secure timing of the MuzzLok® Plan B system. Ideal for PCCs, and AR platforms chambered in 9mm where reduced length, weight, and muzzle rise are priorities while maintaining HUB-mount compatibility.

Performance & Benefits

• Superior recoil reduction: Efficient port design significantly reduces felt recoil and muzzle rise for faster follow-up shots.
• Compact & lightweight: Mini profile minimizes overall length and front-end weight compared to full-size brakes.
• Repeatable timing: Left-hand MuzzLok® nut enables precise orientation and consistent reinstallation with no POI shift concerns.
• 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 muzzle brake 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 brake 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 brake 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.
