Mil-Spec Flat Dark Earth Type II Anodizing

It's the strongest rail DD makes. It's made from a solid piece of aluminum not an extrusion. It mounts similarly to the Lite Rail but doesn't require the gas tube to go through a portion like the Lite Rail when mounting the rail over a low-profile gas block. I 'shaved' my FSB to fit under my Mk18 rail and installed the gas block and gas tube before installing the top rail. Bottom rail is held on with 4 side screws like the Omega rail.

Here's mine mounted on my 12.5" SBR.

Very nice set up and the rail is a big thumbs up. I do wish the manufacturers would standardize the paint scheme to all the other accessories out there so we don't have to worry about what matches.
