This is a Geissele Mk8, black, 13.5" handguard. The anti-rotation tabs were milled just slightly so that it would fit on a BCM Mk2 upper receiver. I included a picture so you can get an idea of what I mean. It still works fine on a regular upper receiver as the set screws are ultimately what makes contact with the receiver and prevent it from rotating. Otherwise the handguard is in great condition, no scratches/dings/marks that I can find. Includes the barrel nut.
