This is where a Nickel Boron bolt carrier group really shines. Nickel Boron is an advanced metal finish that offers high resistance to wear and corrosion as well as having an ultra low co-efficient of friction.
A Nickel Boron BCG with its slick surface will clean up quite a bit easier and faster than a standard BCG with a phosphate finish. The rough phosphate tends to hold the dirt and grit while the Nickel Boron doesn't seem to as much. You will still get carbon build up on the tail of the bolt, but nothing can prevent that.
M16: M16 bolt carrier groups work in both M16s and AR 15s. In fact, an M16 or full auto BCG is the most common form of BCG on the market. First and foremost a full auto rated M16 bolt carrier group cannot make your gun full auto.
As I explained above, the "GREAT BCG" serves to increase reliability, and will not affect accuracy. Don't blame the for not doing what it was not designed to do. Look on the bright side: If you are going to cheap out the rest of the parts of the gun anyway, the BCG will be the most reliable part in the gun.
On the M16 BCG, there's a little more material on the back of the carrier, which allows compatibility with a full auto sear. This means that the M16 BCG weighs a bit more than the AR-15 BCG. It is not unlawful to utilize a M16 machinegun bolt carrier in a semiautomatic AR15 type rifle.”
30-caliber barrel to their rifle without making any other changes, as the . 30-caliber bullet, meaning the bolt and magazine for a . 223 or 5.56 firearm would work for a . 300 BLK round.
NP3 Coatings are a True Composite Coating of Electroless Nickel, Phosphorous and PTFE (Teflon). NP3 is a surface treatment for various metals and alloys that combines sub-micron particles of PTFE (Polytetraflouro-ethylene) with autocatalytically applied nickel/phosphorus.
Nickel Boron Coating for Guns
As with other coatings, a nickel boron finish offers increased lubricity and an easier cleaning process to firearms that are treated with it. A nickel boron finish will give the treated part a silvery metallic appearance and is extremely resistant to corrosion.Electroless nickel plating (or EN plating) is a chemical process that deposits an even layer of nickel-phosphorus or nickel-boron alloy on the surface of a solid substrate, like metal or plastic. The process involves dipping the substrate in a water solution containing nickel salt and a suitable reducing agent.
Most durable possible finish is probably carbo-nitriding, Tenifer or similar process. This is used on Glock, Steyr handguns, current XD's, and various others. It's nearly indestructible as a finish. I don't know if anyone does it aftermarket though.

Parkerizing is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of a chemical phosphate conversion coating. Bonderizing, phosphating, and phosphatizing are other terms associated with the Parkerization process.
The Ultimate Guide to Gun Coatings
- Gun Bluing. Bluing of steel is a traditional way to protect firearms from corrosion while at the same time reducing glare.
- Anodizing. They say diamonds are a girl's best friend, but a gun owner's friend is most definitely a firearm with an anodized finish.
- Parkerizing.
- Nickle Boron.
- Nitride Coating.
- PVD or CVD Coating.
Cerakote is extremely slick, even more so than anodizing; which will help reduce the coefficient of friction—thus reducing heat and wear on the internals of your rifle. Unlike anodizing, Cerakoting is also extremely customizable. Any camouflage, color, or design is not out of the question.
Gun barrel can be anodized, but if it already has some pitting, it won't protect it. The pits are there to stay, unless you paint the barrel.
Melonite is basically salt bath ferritic nitrocarburizing, also known as liquid nitrocarburizing. Melonite is also called Tenifer by Glock. It is the finish we use on all our black slides and its durability is unparalleled by any black finish we have used.
The black oxide process is basically a form of hot bluing with molten hydrated salts that leave the oxide blacker than blue. It forms a magnetite (black iron oxide) finish that is much thinner than the phosphating (Parkerizing) baths produce.
Cerakote ceramic coatings can be used to coat a wide range of properly prepared substrates including: All metals, including: titanium, aluminum, magnesium, copper, brass, stainless steel, etc Scopes (exterior), mounts and other high-quality accessories.
