Sold pending funds This rail came off my factory AAC 300 upper. Was never used, replaced as soon as upper was purchased. From what I can gather these are not cheap, but I'm also not sure if a barrel nut comes with this rail when you order it (anyone know?). This sale is for the rail only. I'm putting price at $125, but will adjust if necessary. I did not remove the rail myself, had a local gun shop do it. Ftf deal I-5 corridor from Eugene to Seattle. Thanks!
