Like the title says I have a YHM lightweight free float (carbine) quad rail for sale. the rail is used (lightly) but the barrel nut, jamb nut and retaining screws are all new. I replaced this with a Spectre length rail and retained the used stuff on my gun. Also comes with the instructions. Does NOT include the front sight or the rail covers. Asking $90 shipped, I paid $179 for it new (I know that is high but I needed it NOW! and ended up buying locally) so my loss is your gain. Oh yeah, I'm in Eugene Or.
