I have a new unfired Colt 6700 20" 1/9 twist A3 upper with matching carry handle. It is from a Blue Label gun with a small front pin, flash hider, and no bayo lug. There are no markings on the upper, however, I can assure you that I bought this as a complete, unfired, Colt rifle. Does not come with charging handle, bolt carrier, or bolt assembly. I will sell this upper for SPF plus shipping obo.
Please email if you have any questions, or for pics at email@example.com
Thanks for looking, Mark
