I have a preban Colt A2 which the gun is the older grey color.Right now the upper is the original upper, but I have put a DPMS 1/8 HBAR w/ free float tube on it. I am going to get a Bushmaster M4 upper, which will be black of course. If I send the lower Colt Reciver out to refinish black, will it decrease the value? Is a preban lower worth the same regardless. Do I have to keep the original upper with the gun. If I ever try to sell it, will it be worth the same, more or less with the M4 upper and matching colors, or if I keep the original upper with the noodley 1/7 barrel. Does any body have the grey lower with a black upper, does it look weird? Or is this just being anal wanting it to match? Would it be worth more with the M4 upper matching? Thanks for any help or comments
