I bought my wife a Colt 6920 awhile back that she had been asking for. Working through some basic TTPs in dry practice it has become obvious that the lightweight Colt 6720 with a pencil barrel would have been a better choice. The only accessories will be a light and an Aimpoint.
As I would like to use the 6920 upper for another build I would like to either acquire a 6720 factory upper or a high quality upper built to spec with similar weight characteristics. My research has yielded mixed result. My searchfu is weak.
As I have been using LMT MRPs for several years I have been out of the market on upper builds for awhile.
Can anyone suggest a vendor that stocks 6720 uppers or a solid lightweight alternative?
