FMA Wire Channel Edition ARC Rail For FAST SF Helmet (Black)

The latest version of the ARC rail system was first used in the new generation of FAST SF BUMP parachute training helmet. On the basis of maintaining the original function, the system adds wire channels and achieves a light weight overall. This design comes from the independent modification of many professional users, and now it is no longer necessary for users to fix the corresponding problems. You can attach cables to the inside of the guide rail using tie straps to reduce the risk of cable tangling. In addition, the rail is compatible with all FAST SF series helmets.
