Just received my new purchase, a colt DOE upper NIB . My only complaint is that I should have purchased one 20yrs ago when I had the chance, I passed on one about 10yrs ago because it was priced too high, now the April fools joke is on me ...this one cost double!
My advice is if its rare NIB , suck it up and pay ...you may not get another chance!
