I have a fixed carry handled upper. A2 sights are installed, but the duster cover assembly and forward assist assembly are not. Upper is from a model 1 sales upper I bought about 7 years ago. A few blems on the shell deflector, but other than that its in great shape. Non M4 cuts Asking 60 shipped for it. Also looking for trades: Pmag 20 rounders Any 20 round AR mags AR57 50 or 30 round mags 5.7 ammo or?
