What is the advantage of a nickel boron BCG?
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 grime while the Nickel Boron doesn’t seem to as much.
What BCG coating is best?
13 Best AR-15 Bolt Carrier Groups (BCG)

What’s better nickel boron or nitride BCG?
A nickel boron bolt carrier group will have greater lubricity and corrosion resistance than both chrome and nitride BCGs. For these reasons, it is a very popular AR-15 BCG finish.
Are phosphate BCG any good?
For hardness, corrosion resistance, smoothness and ease of cleaning, DLC wins. For nostalgia and tradition, phosphate has no competition. All of the finishes listed here are quality finishes and a good BCG will work fine with any of them. Each is a great option if you are looking for a BCG with a black finish.
Which is better black nitride or phosphate?
A nitride exterior will protect the barrel longer than a phosphate exterior finish. However, a chrome-lined, or phosphate, barrel will hold up better to sustained fire than a nitride interior. Nitride has a slight edge in accuracy and price. However, phosphate coated/chrome lined barrels are more common.
Will Nickel Boron rust?
One of boron’s properties that makes it so valuable is its ability to not corrode or rust; this prevents other metals from doing so as well. Borides are considered a precious metal because they have so many different properties that make them worth more than other metals like aluminum and steel.
Which is better nitride or phosphate BCG?
On the basis of performance, nitride wins. For nostalga, phosphate wins. The battle between these two smooth finishes comes down to cost vs performance. Both are excellent finishes that are very hard, smooth and high performing.
Is nitride or phosphate better BCG?
Is bcm a BCG phosphate?
BCM Bolt Carrier Group They’re simple, and they get the job done. The BCM bolt carrier group features a C158 bolt, tool steel extractor/ejector, and a properly staked chrome-lined gas key all housed in a phosphate carrier with a chrome-lined bore.
What color is Nickel Boron?
Hardness: 82 Rc. Max Temperature: 600° F – 700° F. Thickness: 0.00035″ – 0.0005″ Color: Silver – Matte Gray.
What is the difference between phosphate and nitride BCG?
The phosphate works just fine, is tougher to clean and holds oil to it slightly better. The nitride can go longer between cleaning and will function much better without a lubricant in addition to being much easier to clean. I would also expect the nitrided one to wear at a slower rate, therefore lasting longer.
