Breek Arms Plan B Sentinel Caged Flash Hider with Pin-and-Weld Capability

Features

  • Closed-tine, fully shrouded design for superior flash suppression
  • Engineered for pin-and-weld on 14.5″ barrels to meet 16″ federal requirement
  • Plan B/Atlas mounting system for suppressor compatibility
  • NVG-friendly signature reduction with reduced snagging profile
  • 4140 hardened steel with nitride finish

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 .223/5.56 ammunition are tested and rated for 7.5″ barrels and longer. Use of peel washers or shims for installation is highly recommended.
