Hi, I'm thinking about doing a clone project and wanted to use the KAC RAS rail to stay as clone correct as I can. However, I don't like that it's a non-free floating rail. People have mentioned in other threads that the top rail is actually free floating because it attaches to the barrel nut, but it's the bottom rail that makes contact with the handguard cap, and hence the barrel as well. I've also read somewhere that there is a bottom rail known as the SAS-UK RAS Lower that attaches to the barrel nut in the same fashion as the top rail. If so, would this in theory convert the RAS into a free float rail? Any thoughts and/or suggestions on this topic is much appreciated. Thanks!
