Recently I started a new build. It was centered around a few key components, the Rainier Arms Mod3 billet receiver set, Rainier Arms 16″ .223 Wylde barrel made from a Rock Creek Blank, the LANTAC USA E-BCG and the new Fortis Manufacturing 14″ REV II MLOK rail. I just recently finished this build and will begin the process of shooting and reviewing it. Until then I wanted to give you an initial impression of the new REV II MLOK rail.
I have used many Fortis Manufacturing REV rails over the past few years and really like them a lot. Lately Fortis has come out with a few new rails including the new REV II rails which look great. As you would assume they are a modified version of the original REV rail that deletes the bottom picatinny rail section and forward side rail sections for a super sleek design, lighter weight and more flexibility in mounting your KeyMod or MLOK accessories.
The REV II rails mount directly to a Mil Spec AR-15 barrel nut with a rock solid clamp just like the original REV rail. This type of mount is great for a few reasons. One, it creates an insanely solid union between the upper and rail. It also makes it easier for users to upgrade from the standard plastic “Glacier Guard” or other hand guards that use a Delta Ring as they will not need any armorers tools to remove the old barrel nut and install a proprietary barrel nut. Just cut the Delta Ring off, remove the spring, install your low profile gas block and your REV II rail will be on in minutes. Installation of accessories can be done while the rail is installed but can be done much easier by quickly removing the rail instead of installing them while on the rifle.
FIT AND FINISH
Fit and finish on the Fortis Manufacturing rails is second to none with a very nice dark black Type III Hard Coat Anodizing, smooth edges and aggressive lines. Not to mention they just look stinking sexy! As you can see in the picture below I also used the Fortis Manufacturing Low Profile Gas Block which looks great with its similar lines.
Overall I am very impressed with the Fortis Manufacturing REV II rail and would put them very high on the “Recommended List”. They offer these in both KeyMod and MLOK versions all the way from 7″ long to 14″ long. So far there really isn’t anything I would say I don’t like about the rail. One note I would make is that anti-rotation tabs are a great feature but as you may already know, not all billet uppers will accommodate them unless they manufacture of that upper has designed it to work with a rial with anti-rotation tabs. This is not an issue with the rail but more of an issue with manufacturers of billet uppers. The Fortis Billet Upper and Rainier Arms Billet Upper work great with them and many others will too. Check out the entire build below. Once I’ve had some time behind the trigger on this build I will update with more reviews on the different components.
