BLACK NITRIDE
Black Nitride is a process commonly referred to as SBN (Salt bath nitride) and QPQ (quench polish quench). These are a form of nitrocarburizing or a Thermo Chemical treatment that improves wear resistance and corrosion resistance of ferrous metals with little or no dimensional change which causes the hardening of steel. The chemical bath results in a deep dark black with a harder, more durable finish.
NICKEL BORON
Nickel Boron is the top of the line coating, with its superbly smooth finish. It is engineered to minimize on friction by cutting down the surface to surface contact between sliding parts. This finish not only reduces the friction, but it also dissipates heat, allowing for the least wear and tear.
CHROME &
MAGNESIUM PHOSPHATE
Keep the original MIL-SPEC appearance and function. Toolcraft does it right by following the Mil-Spec original standards which have been tried and found true for generations. The bore is coated with hard chrome and the remainder of the 8620 metal that is exposed has a Magnesium Phosphate protection that absorbs the lubricant, causing the carrier to run smoothly from one round to the next.
DLC
Ionbond Diamond-like Carbon is a metal finish applied through a Physical Vapor Deposition (PVD) process. It is a tough corrosion proof coating, with excellent friction properties. The Ionbond Black DLC will not chip, crack or peel, providing you with years of protection against wear while maintaining its integrity. It is so strong that it is virtually scratch proof.
