DD Upper: AR15 Lite Rail or Omega X Rail?

[warlord260]

Get the SAR rail, it's a LOT thinner and a LOT lighter than the older BAR. SAR comes with a titanium bbl nut and is lighter than a DD LITE rail.

They're JUST starting to ship now and in the next few weeks.

Cant find any info on this, i searched. Can you help me out?
Thanks,

just canceled my spikes order. Ordered the daniels special with the omega rail from smartgunners. The spikes quad rail was back ordered 2 months. Not acceptable. Will let you know, optic is already here waiting.
