So long story short, need some super tall 30mm rings. Mounting a Nf nx8 2.5-20x50 on a bat bumblebee. Action doesn't have a full pic rail due to its light weight design, it's interrupted, taking away higher unimounts. The action is in a xlr element 4.0 chassis. I have the xlr mlok NV bridge. Problem is the bridge sits very high. Mounting my clip ir-lr thermal puts it way up for colinier alignment with the day scope. Highest quality low profile rings I can find are 1.5" tall. I am going to look into machining the xlr NV bridge and pic rail for lower rail height.
