Does anybody have any experience with the fortis switch rail in 5.56. I am thinking about picking one up, however, am a bit curious on the durability of the design and the anti rotation properties.

If you have used this rail, is there any anti rotation tabs or something similar to keep the rail from rotating? How well does the clamping device hold?

I have read some reviews and they all seem very positive but I trust the users on here more than the randoms interweb guys. I don't need something that is quick detach...but I just have an itch to try one. The fact that I can get one FDE is a plus as well.
