After doing my research and looking at free float rails from Troy, YHM, LaRue, and Knights Armament, and Daniel Defense, I came to the conclusion that Daniel Defense had the rail for me. This was because of the price, ease of installation, and good reviews that I had read. Most free float rails from the other manufacturers required that the delta nut assembly be removed. To remove the assembly, you'll probably have to use a dremel and cut it off, which is something that I did not want to do. Also, while the other manufacturers come close in price, they are not as easy to install nor are they proven to perform as well as the Daniel Defense Omega.
Installation of the Omega rails was a breeze which took me all of 5 minutes, literally. All you have to do is take off your stock handguards, attach the Omega rails in the handguard's place, and tighten a few screws and allen set screws. The flat head set screws attach the two parts of the rail to each other and the allen head set screws attaches the rail to the delta ring (far left in the picture).
The way the Omega rail attaches to the rifle had me worried until I took it to the range. This is because the only thing attaching the rail to the rifle are 4 allen head set screws at the base of the delta ring (far left in the picture above). This gives support to the lower portion of the rail, but there is nothing holding the rail to the upper part of the delta ring (far right in the picture above). You would think that you could shove the rail around at the upper base, but the rail stays installed firmly. It doesn't move unless you give it some strong force.
After going to the range and firing a few hundred rounds, I can finally say that I strongly approve of the Daniel Defense Omega rail. It held up great and didn't rotate or come loose. The rail also dissapated heat much faster and much better than the stock handguards. I should also mention that the finish on the rail is top notch and did not scratch or mar after mounting and unmounting various accessories.
