Is there enough room up front to run an x300 and DD Fixed sight or am I going to have to go with the V3? Thanks,
Look at the picture on the DD Website:

Picture 4 shows the sight mounted in slot T46.
Picture 3 leads me to believe there are 6 lugs being used, with 7 flats.
It looks like they used their 15’ Lite Rail III:

A look at picture 2 would seem to indicate that the set-up pictured on the front sight page used 7 flats.
The ALG EMR V2 has 4 lugs and 5 flats - I don’t think it would work.
Why not get a EMR V1 and use two co-witness rails?
If you are dead set on the V2 perhaps the Roschworks SL1 would work for you. I’ve been using one for a while now and I like it a lot.
