AR-15 (EN) Electroless Nickel Complete Bolt Carrier Group

M16 (EN) Electroless Nickel Complete Bolt Carrier Group

Phase 5 EN (Electroless Nickel Plated) Drop In M16 Bolt Carrier Group.

***NEW deburring / polishing process which creates a smoother
slicker more advanced finish.***

The EN plated Bolt Carrier Group enhances reliability, lessens cleaning time,
improves corrosion resistance and minimizes required bolt lubrication.

- EN plated bolt carrier, heat treated & hardened.
- Hardened gas key, grade 8 hardened fasteners, type III sealing
- Black phosphate HPT/MPI bolt and extractor with Mil-Spec gas rings.

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.

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.
