Keymod is the future of rails for the military, and this is already being implemented with contracts from KAC/KMC. This translates into commercial and LE proliferation. Rails are still going to be relevant, but other proprietary slot-mounting systems are not going to reach the level of popularity that Keymod will. There are numerous accessories out for Keymod, and there are even more coming out every month.
I have been running a BCM KMR13 rail for a little while and it's an outstanding handguard. The thing is ridiculously light since it's made of a magnesium alloy. My 16" with KMR13 13" rail and lightweight profile DD barrel is lighter than my 11.5" SBR with a 10" railed Daniel Defense AR15 LITE 10.0 Rail.
As HMAC pointed out, several companies like Noveske, KAC, BCM, Fortis, Geissele, Midwest Industries, and others have Keymod options. More are on the way.
My 11.5" is getting a BCM KMR10 in the near future. I'm loving the smaller radius and lighter weight.
