You know this is a tough choice when you think about quality, as they are both excellent companies. The first complete semi-custom upper I ever purchased was a Daniel Defense complete upper. However my last two have been BCM.

With quality being taken care of with either choice, the decision will probably come down to configuration, and price. All my ARs have Daniel Defense rails, but when I look at the BCM line I see better choices for configuration and a better price.

After a complete DD upper, a DD lower, two BCM uppers and a BCM lower, my next AR purchase will be another BCM.
