Defective acog - Trijicon 1.5x16S Compact Dual Illuminated ACOG Scope

I've been looking for one of these for a few years. Prior to getting out the Army, I went from using a SAW/249 to going to a M/4 w/Acog. I met someone at a range with this smaller version of the 1.5x16. I recall that it has the black horse shoe with the red dot aling with small range numbers, although it was not large as the acog in service, it was not hard to read and was easy to place on target. Immediately fell in lobe with it. Wrote down the model to remember. Fast fwd, I've been able to order my own, but mines is nearly impossible to see nor does the red dot display much. I am assuming there is a defect and require a replacement.
