Based on the Ops Core ARC Rail, the Crye AirFrame Rails use the same proprietary interface system as the Ops Core FAST system. This allows operators to attach a host of accessories to their helmet using the same mounting provisions already available. The AirFrame Rails also allow for the attachment of an Oxygen Mask for use in HALO/HAHO operations. Removable NVG stabilizer bungees and hooks help eliminate wobble from your NODs while an innovative cable retention tie-down rack helps manage your remote battery pack cords. The AirFrame Rail system is used under license from Ops Core.
If you are going to run an AirFrame Ballistic Helmet, you ought to have these rails!
