I just got a dpms upper for a steal. Anyhow the rear carry handle is milspec height and the front sight is a none f marked a2 fsb. Anyhow I don't wanna pay 15 bucks for a taller front sight. I know some has to have a bushmaster, dpms, or other commercial height carry handle. I will trade even with you. The one I have looks new and has no forge markings but had a 75 buck price tag on it. Anyhow it looks new. I will trade for a commercial type rear sight as long as its in workin condition it can be used. Pm me I don't get emails unless I'm at work.
