The Plan B Sentinel solves the problem of needing effective flash suppression for night vision operations while maintaining suppressor compatibility and pin-and-weld capability for 14.5″ barrel builds. It works exceptionally well for tactical applications, night shooting, and builds requiring federal compliance without SBR registration. The closed-tine shrouded design sets it apart by eliminating snag hazards while providing superior flash suppression and NVG-compatible signature reduction in a compact package.
Note: Sentinel flash hiders using .308 ammunition are tested and rated for 10″ barrels and longer. Use of peel washers or shims for installation is highly recommended.
