Geissele Mk4 Rail. DDC. This is one of the original (non-Federal) versions that was 9.5" long, PN 05-283.  The current (non-Federal) Mk4 is 9.3" long with PN 05-283S.
6 M-LOK rail covers are included. These have been dyed to better match the rail color.

The rail is in good overall condition with normal signs of being used but not abused. The exterior shows some light wear, primarily on the picatinny sections. Inside the rail edges of some of the M-LOK slots show wear from the M-LOK nuts. The barrel nut shows a couple cosmetic nicks.

The largest and only area worth pointing out specifically is the worn area below the set-screw on the lower right side of the tab that would be located directly above the receiver's front pivot. A larger-headed-than-OEM pivot pin was initially used and I did not realize it would interfere with the set screw tab of the Geissele rail when the rail rotated. It wore a clearance channel in the bottom side of the tab. I dressed it and blackened it. It has zero effect on the fit or function and is pretty much only visible when attached to a lower if you are looking for it.

I can provide additional photos if requested.
