• Hardened gas key
• Grade 8 hardened fasteners
• Type III sealing compound
• Black phosphate HPT/MPI bolt and extractor with Mil-Spec gas rings

Electroless Nickel Plating (EN) is an auto-catalytic chemical technique used to deposit a layer of nickel-phosphorus or nickel-boron alloy on a solid workpiece, such as metal or plastic. Electroless nickel plating is an auto-catalytic reaction used to deposit a coating of nickel on a substrate. Unlike electroplating, it is not necessary to pass an electric current through the solution to form a deposit. This plating technique is to prevent corrosion and wear. EN electroless nickel plating has several advantages versus electroplating, it provides an even deposit regardless of workpiece geometry, and with the proper per-plate catalyst, can deposit on non-conductive surfaces.

COMPLETE ELECTROLESS NICKEL (EN) PLATED, PRE-POLISHED INNER CARRIER Cleaning is minimal, usually requiring only a soft cloth. Permits firing for longer periods of time between cleaning, as dirt and powder residue has no wet or oily surface to cling to. EN provides a high lubricity and low friction co-efficient, greatly increasing the life expectancy of a firearm due to reduced friction wear.
