Nickel Boron is a surface coating and can be applied to a wide range of metals such as steel, stainless steel, nickel alloys, aluminum, cobalt alloys, copper alloys and titanium. It is used as a great alternative to chrome plating. Nickel boron, which is very resistant to wear and corrosion, provides great benefit to the areas where it will be used or coated.
What is Nickel Boron Coating?
Nickel boron plating (NiB plating) is used as a well-known nickel deposition technique. Nickel Boron coatings serve to protect against corrosion, reduce stress levels on coated surfaces and increase wear resistance, as well as increase functionality on the surface on which they are coated. It is also used for many purposes, including maximizing lubricity, which contributes to maintaining surface aesthetics. Nickel-Boron (NiB) coating is actually a surface treatment. It nucleates in the surface atoms of metals, becoming part of the metal rather than being applied only to the outside. In addition, the machined surface benefits by eliminating the cost, weight and degradation problem of conventional hardened metals as the substrate becomes harder than the substrate itself.
What is Nickel Boron Used For?
Nickel Boron is highly resistant to corrosion, and in extremely harsh climates and conflict zones, firearms are coated with this substance. The low coefficient of friction it provides contributes to the resistance of non-electric nickel barrel process extensions to friction heat generation and allows it to protect the barrels for life. The AR-15 weapon, a firearm used in military conflicts all over the planet, provides a light shot as nickel boron is surface resistant.
One of the most important features of Nickel Boron is that it is not sticky like phosphate polish. It is more slippery and makes cleaning easier, especially if it is not cleaned regularly. Nickel Boron is preferred in a BCG due to its slippery, lubricated surface. Since the critical characters of the bolt carrier system (from the inside out) have a low coefficient of friction, everything works more smoothly. Lubrication helps to reduce the friction of the nickel-plated surface between the mating surfaces of the carrier, the upper receiver and the cam pin. These areas can cause friction, resulting in loss of carrier velocity, and inability to properly feed or remove bullets.
Nickel Boron plating is very functional and useful for firearms. These benefits include:
- High melting point (1,976 degrees Fahrenheit) protected against excessive heat
- High friction resistance
- Increased ductility
- Strong heat dissipation properties
- No risk of hydrogen fragility
Why Nickel Boron BCG?
All of the AR15 components, the bolt carrier assembly is undoubtedly the most critical component for trouble-free operation. It is not only the most complex component, but also the most hard-working component. The bolt is the most advanced part of an AR BCG.
During firing, it must suitably contain the high chamber pressures of the 223/556 cartridge (52,000 - 70,000 + psi) or 300 Blackout cartridges (55,000 psi). It is also responsible for guiding the firing needle to the fuse, pulling out the fired shell, feeding the new cartridge into the chamber, and finally properly locking it to the barrel extension. Generally, the Bolt Carrier Group does all this without error, even when it is dirty and repeatedly neglected. All these tasks benefit from proper lubrication. Proper lubrication reduces friction between the mating surfaces of the carrier, the upper receiver, the cam pin, the bolt, and the barrel extension. Lack of lubrication in these areas increases friction and can result in loss of carrier speed and proper feeding, removal or removal of bullets.
This is where the Nickel Boron bolt carrier assembly is really needed. Nickel Boron is an advanced metal coating that offers high resistance to wear and corrosion as well as having an ultra-low coefficient of friction. When the critical surfaces of the bolt carrier assembly (both inside and outside) start with a low coefficient of friction, everything enters a softer cycle and requires less lubrication. That's why some of the world's top barrel manufacturers use Nickel Boron plated barrel extensions on some of their high-end barrels.
What this means in practice is that a Nickel Boron BCG will still be slippery even when the oil evaporates, flows or burns during shooting. The result is increased reliability when the rifle is dirty or under-lubricated. This is even more important with an AR gun or a suppressed gun. Because of the short gas systems in AR guns, they tend to get dirty faster than AR15s with longer gas systems.
Suppressed pistols reactivate carbon contamination and take advantage of the self-lubricating properties of Nickel Boron. Nickel Boron BCGs remain slippery during extraction regardless of whether the oil evaporates, rubs or burns. This improves reliability when the rifle is used less frequently or when it is not lubricated sufficiently. This also applies to suppressed weapons and AR pistols.
In terms of cleanliness:
With its slippery surface, a Nickel Boron BCG cleans slightly easier and faster than a standard BCG with a phosphate coating. Nickel Boron coating does not show dirt. Only the tail of the bolt will have carbon deposits, but no matter what polish you have, this situation is inevitable. The silver color it provides is much more useful than other substances.
From aesthetic point of view
Aesthetics, of course, vary depending on the person, but usually people can love the contrast of nickel boron plating against the rest of a black rifle. So even if you're looking for a way to decorate your AR-15 or appreciate quality equipment that looks good, Nickel Boron BCG can be something to consider for your AR. These are the top 3 reasons why a Nickel Boron bolt carrier assembly is a valuable upgrade for your AR15 rifle, carbine or AR gun.
