OPSMEN Helmet Rails Adapter Attachment Kit for Earmor Electronic Headsets (Type: ARC)

"I have a team wendy exfil helmet and these adapters plugged right into the real helmet no problems. Creates a perfect seal around the ears on uneven seal. If you have a team wendy exfil or exfil repro then I highly recommend these

"I have the M-Lok version as I have a PTS MTEK Flux. Shipped with one of the screws being the wrong size. It sticks out far from the rails by a solid inch, but other than that it's a pretty solid mount.

"They, work... but my god they are hard to work with, these gave me an at-home workout because they were so stiff and hard to install. If you mess up, your hands will be in a whole lot of pain trying to adjust everything. These rotate outwards to stow the ear pro, but they do not click in or out.
