FAXON TITANIUM EXTENDED PLAN B → HUB ADAPTER

Lightweight, extended-length titanium adapter for superior clearance and reach. The Faxon Titanium Extended Plan B → Hub Adapter (FF-MD-SIL-HUB-PB-04) is precision-machined from Grade 5 Titanium (Ti-6Al-4V) and designed to provide a secure, repeatable interface from MuzzLok® Plan B Compatible devices (and similar Plan B muzzle devices) to hub-mount suppressors such as Faxon HARMONIX® and CORESYNC®. The extended length offers additional reach for better suppressor positioning and clearance on certain setups, while titanium construction significantly reduces weight.

Why Use the Faxon Titanium Extended Plan B → Hub Adapter?

This lightweight, extended titanium adapter allows shooters to leverage the fast, repeatable timing and secure lockup of MuzzLok® Plan B-style (and similar) muzzle devices while attaching modern hub-mount suppressors. The added length improves clearance and positioning on certain rifle configurations, while the Grade 5 titanium construction reduces front-end weight and offers excellent corrosion resistance and strength-to-weight performance.

Benefits

• Extended reach: Provides additional length for better suppressor clearance and positioning on select setups
• Ultra-lightweight: Titanium construction significantly reduces added weight compared to steel adapters
• Repeatable mechanical interface: Maintains timing and alignment between Plan B devices and hub mounts
• Precision thread geometry: Minimizes wobble and ensures concentricity for consistent performance
• Superior corrosion resistance: Titanium naturally resists rust and harsh environments
