Unlike FNC, these methods do not leave a black finish on the barrel, so the steel must be. Each Seekins Precision NX15 Bolt Carrier Group must pass magnetic particle inspection (MPI) before it is allowed to leave the Seekins factory in Idaho. ), Electroless Nickel Teflon, Electroless nickel with boron nitride, black nickel, black nickel teflon, zinc nickel and ceramic topcoats, WMD is able to offer the right coating for the right application. It's a chemical treatment that results in a hardened black surface that is both durable and highly corrosion resistant. We will take your stainless (no Nitride/Melonite/QPQ barrels) barrel chambered in 6. For the total immersion test (DIN 50905/part 4) a solution of 3 % common salt and 1 % hydrogen peroxide (H 2O 2) is used as the corrosive medium. A barrel is simply button rifled then put through the melonite process (QPQ actually stands for Quench-Polish-Quench if you didn't already know, which is the specific process used) which rearranges the steel molecules to be more symmetrical, therefore harder. Kind of price for a minimum order. KAK INDUSTRY is a design and manufacturing company that specializes in wildcat uppers for LR-308 platform and AR15. As with all our Melonite/QPQ barrels, we ensure the barrel and extension are separate during the 1000+ degree treatment so there is no risk of the extension working loose. for the QPQ®-Process. The leading provider of heat treatment and specialist thermal processing services worldwide Heat treatment encompasses a variety of techniques and specialist engineering processes which improve the properties of metals and alloys and extend the life of components and is a vital part of any manufacturing process. This is a solid, reliable BCG. Nitride Coating (Nitrocarburizing, Black nitride, Melonite™, QPQ, Tennifer™) Nitride finish, commonly known by the brand names of Melonite™ or Tennifer™, isn't technically a coating. The Salt Bath Nitride process is a Thermo Chemical treatment that improves wear resistance and corrosion resistance of ferrous metals with little or no dimensional change. Three steps are involved: nitrocarburize ("quench"), polish, and post-oxidize ("quench"). Hence, American companies such as Smith and Wesson or Springfield Arsenal use the Melonite treatment process instead, which is also a ferritic nitrocarburizing process, but uses different salts and a slightly modified process to produce the same results. But it is more EPA compliant.
