Decided against using my Aimpoint, left it on my 300BLK SBR and put a Vortex Viper PST 1x4 in an Aero lightweight 30mm tube. Could have gone lighter with the BCG but I don't use anything but BCM BCGs. Could have gone lighter with the buffer tube instead of the capture spring but I am shooting suppressed, which worked out perfectly with the Griffin muzzle device needed for my Optimus. I went with the Alpha rail instead of the KMR because I was tired of waiting for it.
