NIB-X Coating Gives Superior Performance

Nickel Boron exterior gives this bolt an incredibly hard finish that protects against wear and corrosion for the ultimate in durability. The extreme smoothness and built-in lubricity of the coating also reduces friction and gives carbon deposits nowhere to stick, so bolt can be easily wiped clean with a cloth or nylon brush. Comes complete with ejector, extractor, and gas rings installed.
