So easy to use and mount - SureFire Ops Core Helmet Rail Mount

Honestly, I didnt think that such a small piece would make all the difference. The standard mount for it was pretty hard to use with my ARC rails, it was a clamp on style, so I bought an adapter from another company, and it was a better fit, but still didnt like it. Bought this one, and it was easy to install, but most of all gives you the ability to orient your light in different angles. Should have used this one from the beginning.
