Question on anodizing ?

[reaper5.56]

I was browsing the US Anodizing website and noticed they offer a US Navy service anodized coating. Are Navy M16's and M4's really coated differently than all the others?

This what it says on there web page

US NAVY SERVICE: This service is available to complete firearms or components. It is intended for any firearm subjected to extreme conditions. A "must" for Military or Law Enforcement applications!
• All parts will be Anodized or Phosphate coated. (Mil Spec).
•All parts will be top coated with our Xtremcoat™ (Ceramic/Moly/Teflon).
•Friction contact surfaces will be coated with Xtremcoat™ (Dry Film Lube).
•Parts exposed to high heat will be coated with Xtremcoat™ (Heat Barrier).
These coatings, meet Military requirements for saltwater exposure. Test conducted for 500-hour salt spray (5% salt), the equivalent of a seven-year exposure. The same coatings are used on US Navy, Special Operation (SEAL) weapon systems

No, all services use the same coatings because they receive their standard firearms from DLA. The only exception to this is SOC weapons which can procure their own weapons through direct contacts.

Basically all this company is providing is cerakote or nitriding. Don't be tricked by marketing.
