I have a black 15" Alpha rail plus a customized FDE Magpul MOE vertical grip (modified and reinforced to fit flush with the Alpha rail). Also included is the original BCM barrel nut if you want/need it.
$150 shipped (in original box for the rail).
I also have a Troy fixed front sight (FDE color). It is used but not abused, and was mounted on the above rail.
$35 shipped SPF
If combined, we can work out a deal on the shipping etc.
