About Robar NP3
NP3 finish is an electroless nickel-based finish for steel, stainless steel and aluminum alloys that co-deposits sub-micron particles of PTFE (polytetrafluoroethylene), otherwise known as Teflon, with electroless nickel.
NP3 metal finish offers many benefits. NP3 permits firing for longer periods of time between cleaning, dirt and powder residue have no wet or oily surface to cling to. When cleaning is required, the effort needed is minimal - usually requiring only a soft cloth.
NP3 is very corrosion resistant. It provides a high lubricity and low friction co-efficient, greatly increasing the life expectancy of a firearm due to reduced friction wear. NP3 is a satin gray, non-reflective color ideal for all firearms.
