So, for my Block IIish build, I need a Daniel Defense Lite FSP rail in Flat Dark Earth. The problem is, I can only find the Lite FSP rail in Black, never in FDE. I can, however, find the DD Omega X FSP rail in FDE relatively easily. So two questions: 1. Are there any Lite FSP rails in FDE even on the market? 2. If there isn't and I go with the Omega X, will I need to remove the delta ring?
