I have 4 used RAS for the M4. These are NOT FF. Included is only the handguard and 4 full length panels. I have 2 in very good shape just some surface marks where they mounted. Asking $130 shipped CONUS. The other 2 are in good shape but show a few more mounting marks and the panels have some scratches and wear marks. Asking $110 shipped. Pis on request.
