The MK18 rail system is something everyone loves because it makes your gun look mean. The Castellan MK18C rail system makes your gun look lean and mean. Shorter than your average rail, this is purpose built for a CQB gun. The rail mounts directly onto the barrel nut, giving you four sides of picatinny rails for accessories and attachments.
