codeRED ARC Rail Adapter Installation


Installing our CR-TAC/MILTAC Dual Muff Headsets onto an EXFIL 2.0 or 3.0 helmet can be confusing at first glance, but really it's simple. It comes down to the preference of attachments that are available to the system.

Rail 2.0 - This is the rail 2.0 mounting system, which is made of a very rigid polymer. It is a one-of-a-kind system designed by Team Wendy, which means it only accepts Team Wendy accessories. Fortunately, Team Wendy offers a plethora of accessories, and this helmet is compatible with all rail 2.0 accessories. Headset adapters and picatinny rails are two examples of these accessories.

Rail 3.0 - Team Wendy has been producing their 3.0 system since 2020. It's not an improvement over 2.0, but a completely different attachment that serves a different purpose. The 3.0 rail is intended for mounting the EXFIL ballistic visor and face shield.
