NSR vs REV ii/REV Switch

[M4CARBINE556]

Hey guys, I need your help deciding on a rail for my 10.5 inch 300 BLK build. I've got the thing almost completed, but I need a handguard. I've narrowed it down to the Noveske NSR 9" and the new Fortis REV II or Switch, both in 9". I know the REV II is coming in a 9" but I'm not sure about the Switch does anybody know? So out of these options, which would you choose,and why? Thanks. BTW its a MUR 1A upper.

I'd opt for the NSR, personally. The NSR is probably slimmer than the Fortis rails you listed. I am not sure about the weight, but the NSR was the lightest rail on the market until the BCM KMR came out.
I have NSR's on my ARs, and am a happy camper.

I haven't seen a NSR rail in stock anywhere in months.
Why not the BCM KMR 9"?

Thanks man, I'm leaning towards the NSR.

I can't find a 9" KMR or NSR anywhere. Does anyone have experience with the Centurian CMR rails?
