Looking for complete AR15 upper

[LPfishnTIM]

mine came complete already assembled, HH make sure you order a M16 BCG its better balanced, the firing pin is better covered and it should last longer, Core15 has a nickel boron coated one that comes with trigger and charging handle for $200 or if you just want to save money they have a bcg for $120 and a charging handle for $20 which would make the total cost of the rifle even less then 6oo. only thing left is a rear sight!
