Fortis REV 12" rail first impressions
I got in on the Rainier Arms pre-order for the new Fortis REV rails last month. They promised delivery by the end of January and they met that promise. That right there was a big thumbs up for Rainier Arms considering the current climate.
The Fortis is packaged in a simple cardboard tube. There are no instructions, but for anyone who has worked on an AR-15 the installation is self explanatory. If you are not currently running a low profile gas block and GI barrel nut you will have to install them to run this rail. My setup below is a BCM 16" barrel, with a BCM lopro gasblock, and BCM barrel nut on an Aero Precision upper. To install, slide the rail over the whole works.

Snap it in place over the barrel nut...

Install the cap piece through the dovetail and torque down the screws. You will find that the cap will bottom on the rail once the screws are tight. This is a nice feature that gives a good visual indication that it is seated properly and offers some protection at stopping the screws instead of stripping them out. Further protection at stripping the screws is the stainless inserts they screw into.

The Fortis rail has anti rotation tabs on both sides.
