We take a look at the Ops-Core Vented AMP Helmet rail arms to see all the new features. I've used these in the past so I'm excited to see some upgrades as we go over installation, stowage, and fit also. Plus the craziest thing - NFMI still works when it's in vent mode. Make sure to let us know your thoughts
