Osprey Defense OPS-420 Gas Piston Retrofit Conversion Kit with Fail Zero Nickel Boron Finish AR-15 Standard Barrel Diameter Rifle Length
The Osprey Defense OPS-416 Gas Piston Retrofit Conversion Kit with Fail Zero Nickel Boron Finish are identical to the standard Osprey Defense conversions except that the piston chamber, piston, operation rod and solid 1 piece bolt carrier all coated with the Fail Zero EXO Nickel Boron finish.
According to the manufacturer, this finish provides a permanently lubricious surface, harder than the substrate itself, which eliminates the need for grease, oil, or any wet lubrication for the life of the weapon. Unlike films, conventional coatings and applied lubricants, it will never rub off, never flake off, never build up crud. EXO Technology eliminates wet-lubrication failures of critical components, giving you an "active weapon advantage" under all conditions and proven in DoD testing.
