Faxon MuzzLok® Stainless Steel Plan B Flash Hider | 5/8×24 | .375″ Bore
Effective Flash Suppression with Suppressor-Ready Precision
The Faxon MuzzLok® Stainless Steel Plan B Flash Hider offers superior flash reduction and effortless suppressor compatibility for .30-caliber and 6.5mm rifles. Machined entirely in the U.S.A. from premium stainless steel, this device utilizes Faxon’s patented MuzzLok® system for quick, tool-free installation and secure timing. The 5/8×24 thread pitch and .375″ bore make it ideal for .308 WIN, 300 BLK, 6.5 Creedmoor, and 6.5 Grendel platforms, including large-frame AR-10 builds and precision bolt rifles.
MuzzLok® Technology – No Shims or Crush Washers Required
Faxon’s MuzzLok® system simplifies installation by removing the need for shims or crush washers. The locking collar design allows the flash hider to be hand-timed and locked firmly in place, maintaining precise suppressor alignment and ensuring consistent performance even after repeated use.
Plan B Suppressor Mount Compatibility
This flash hider is engineered to work seamlessly with Plan B-style QD suppressor systems. Its precision taper interface ensures a solid, concentric lockup for repeatable point of impact. Shooters can attach or remove compatible suppressors quickly, making it ideal for multi-configuration rifles where reliability and accuracy are essential.
Durable Stainless Steel Construction
Each Faxon flash hider is CNC-machined from stainless steel and finished in a durable QPQ nitride coating that resists corrosion, heat, and carbon buildup. This hard finish maintains the clean internal bore surface for consistent gas dispersion and long-term performance, even under sustained fire.
