The Sanders Armory Corp 7.62 x 39 MPI Tested Phosphate Bolt Head with Phosphate Extractor. The 9310 Steel MPI Tested bolt with Nitride finish that will not flake off, produces less friction while increasing the life of the bolt head. The 7.62 x39 Extractor has been Phosphate treated per MIL-STD-171 to ensure it will not crack, fracture or shatter but will be protected from wear and elements. 1 year warranty against manufacturers defects.

Note: While properly performed nitrocarburization treatment (Black Nitride) is great for a bolt carrier, it is a sub-par choice for bolts and extractors. The nitriding process will cause these parts to become brittle. This translates to decreased bolt life, usually significantly. The nitriding process involves submerging the steel in a liquid salt bath that is over 1,000 degrees. We take extra steps to make sure the heat treating, and stress relieving of these steel parts has not been compromised.  

To maintain heat treating, strength and reliability, our bolts and extractors are phosphate coated.
