Raptor Tactical created their Sentinel Inside Helmet Skullcrusher System as a modular component of a helmet system so that the user can shed the OPS-CORE ballistic shell when not needed but retain use of night vision devices.

The system allows for mounting any night vision device, cable management, counterweight pouch, or battery pack. It is compatible with the Wilcox lanyard and features a one-size-fits-all design, accommodating helmet sizes from Small to X-Large.

Conversion takes approximately 10 minutes to transform your existing ballistic OPS-CORE helmet into a fully functional system. An OPS-CORE chinstrap system is required for proper installation.
