The Fortis Standard Castle Nut is manufactured from a solid piece of billet aircraft grade 7075-T6 aluminum that offers a significant weight reduction over a normal Mil-Spec castle nut. If you're trying to save ounces, this is a great way to do so without sacrificing durability. The castle nut will fit onto Mil-Spec buffer tubes and quickly upgrade the form and function of your build. Uses a standard castle nut wrench to install.
