Description:
The Contractor Series - Standard Castle Nut is manufactured from a solid piece of billet 17-4 Stainless steel that offers a significant boost in strength compared to your mil-spec castle nut. We built this for durability in mind and taking everything you're able to throw at it. Still lightweight and only weighing .60 ounces, the castle nut will fit onto mil-spec buffer tubes and quickly upgrade the form and function of your build.
