You know, I get tired of the guys who say "Well, my gun works fine, so I don't care." Well, obviously, this dude cares. Probably because he sunk $500-plus into an upper, and it looks like frozen grape juice. Yeah-I care. But I figured that would be Bushmaster's response. They weren't very helpful last time either. That's the problem here in some of these forums. When a dude posts about a problem, he is jumped on, and told he is a liar, and the manufacturer is the greatest in the world, and nobody else has ever had a problem. Well, this purple issue IS a problem, and it should be taken care of by the MANUFACTURER, not the distributor. I didn't really pursue it with my DCM, because BOTH the upper and lower are purple. Especially in the sun viewed through sunglasses at a match!!! "How'd you get that purple finish on your gun??" "It looks cool!" Gee, thanks.
