This item is not available to the general public and cannot be purchased online. Please email us for a quote.


The Sentry offers the same level of protective head coverage as the US Army ACH/ECH with improved interoperability between communication headsets, visors, and accessories for mandible protection. It also provides better hearing localization and attenuation than the ACH with a modified ear area shape, and is compatible with ARC Rail mounted COMMs and hearing protection devices.

  • Completely redesigned full ear helmet solution
  • The XP version of the shell is built using hybrid composite ballistic materials that weigh a lb less than the ACH while meeting all of the ballistic performance requirements of the US Army  CO/PD-05-04 2007 specification
  • The Worm-Dial adjustable fitband with replaceable front, nape, and side pads quickly detaches to allow convenient donning / doffing of COMMs headsets with headbands while being more compact than the Occ-Dial version used in the FAST helmet models
  • The ventilated multi-impact liner has repositionable EPP impact pads and LDV closed-cell comfort foam that is not affected by temperature, altitude, or moisture
  • Gives helmet 4x more stability than standard issue ACH helmet suspension / retention products
  • Sentry has additional ballistic capability with ballistic Moto Mandible and ballistic Moto Visor
  • Compatible with headband COMMs and external rail-mounted COMMS like the RAC headset
  • Same ARC and bungee benefits as the FAST Helmet
  • Ops-Core Skeleton Shroud included on the helmet: compatible with front mount visors, flashlights and other visual enhancement devices
  • This product is restricted to US Military, Law Enforcement, DOD and Security personnel
