I have an all original Colt 6520. It has an integrated carry handle. If I replaced it with the below flat top Colt upper and transferred all the upper parts over to that upper, would that affect any collector value it might have? I would keep the original upper of course.
I probably won't do this but was thinking of putting an optic on it.
