The upper receiver model NDS-15U is replacing the previously offered NDS-32 upper. Both incorporate the trigger charging handle, but the NDS-15U is more authentic to the original prototype.
The first anodized batch of the most recently machined NDS-15U uppers has been graded, and all are BLEM grade.
This thread has pics of the forgings used for the NDS-604 and NDS-15U uppers, and anodized NDS-604 uppers -

The same cosmetic dark streaking as seen on the NDS-604 uppers is the reason for the BLEM grade for the NDS-15U upper. The cosmetic issue is minor and will not affect function.
We expect this BLEM issue will be recurring in the entire production run of NDS-15U uppers.
