For those want an Ops-Core FAST bump Helmet, but could not get one due to being out of stock always, or it's just too expensive as an airsoft gear (US$671!!!), eBaybanned came up with the next best thing, a MICH 2001 Helmet with a N Side Rail Mount. Available in tan and OD colour, you can just repaint it to multicam look if you want it closer the the Ops-Core Helmet. And it's US$75, free shipping included. Good for those who want to mount a helmet cam.
