FAQ

What is the best finish for a bolt carrier group?

This is a question that we get asked a lot, and it’s one that doesn’t have a straightforward answer. There are a number of different finishes available for bolt carrier groups (BCGs), and each has its own advantages and disadvantages. In this article, we’ll take a look at some of the most popular BCG finishes on the market and help you decide which one is right for you.

One of the most popular finishes for BCGs is black nitride. Black nitride is a low-friction finish that provides excellent wear resistance and corrosion protection. It’s also relatively easy to apply, which makes it a popular choice for gun manufacturers. Black nitride BCGs typically have a dark, matte finish that some shooters find aesthetically pleasing.

Another popular finish for BCGs is phosphate. Phosphate finishes are typically applied to Mil-Spec parts, and they provide good corrosion resistance and lubricity. Phosphate finishes can be applied in a variety of colors, but the most common is black. Phosphate-finished BCGs often have a slightly rough surface texture that can help them hold lubricant better than smooth finishes like black nitride.

One of the newest finishes on the market is nickel boron (NiB). NiB is a high-performance finish that provides excellent wear resistance, corrosion protection, and lubricity. It’s also extremely easy to clean, which makes it a popular choice for competition shooters. NiB-finished BCGs typically have a bright, shiny finish that some shooters find aesthetically pleasing.

No matter which finish you choose for your BCG, it’s important to keep it clean and well-lubricated. A dirty or poorly-lubricated BCG can cause a number of problems, including increased wear, decreased performance, and even catastrophic failure. Be sure to follow the manufacturer’s recommendations for cleaning and lubricating your BCG.

If you’re looking for the best possible performance from your BCG, nickel boron is the way to go. NiB provides excellent wear resistance, corrosion protection, and lubricity, and it’s also very easy to clean. However, NiB-finished BCGs are usually more expensive than other finishes.

If you’re on a budget, black nitride is a good choice. It’s less expensive than NiB, and it still provides good wear resistance and corrosion protection. However, black nitride isn’t quite as easy to clean as NiB, so you may have to put in a bit more work to keep your BCG running smoothly.

Phosphate is a good middle-of-the-road option. It’s less expensive than NiB but more expensive than black nitride. Phosphate provides good wear resistance and corrosion protection, and it’s available in a variety of colors. However, phosphate can be a bit difficult to clean, so you may want to consider another finish if easy cleaning is a priority.

No matter which finish you choose, be sure to keep your BCG clean and well-lubricated. A dirty or poorly-lubricated BCG can cause a number of problems, including increased wear, decreased performance, and even catastrophic failure. Follow the manufacturer’s recommendations for cleaning and lubricating your BCG, and inspect it regularly for signs of wear or damage. With proper care, your BCG will provide years of reliable service.

How often do you replace BCG?

Most bolt carrier groups will last for tens of thousands of rounds without any issues. However, after a certain amount of use, it is inevitable that parts will start to wear out and require replacement. Depending on how often you shoot and how well you maintain your BCG, you may need to replace it every few years or so.

When shopping for a new BCG, there are a few things you should keep in mind. First, make sure that the BCG you select is compatible with the type of firearm you have. Second, pay attention to the finish of the BCG. Many companies offer different finishes that can provide different levels of protection against corrosion and wear.

Third, consider the weight of the BCG. Heavier BCGs will help to reduce recoil, but they can also make your gun more difficult to handle. Lastly, take a look at the price of the BCG. While you don’t want to skimp on quality, there is no need to spend more than you have to.

How to care coated BCG properly?

It is important to know how to care for your coated bolt carrier group properly in order to maintain its finish and prevent damage. Here are some tips:

  • Avoid using harsh chemicals or cleaners on your coated BCG. This can strip the coating and leave the metal exposed to corrosion.
  • If you must clean your BCG, use a mild soap and water solution. Be sure to rinse thoroughly and dry completely before storing or using.
  • Avoid getting any lubricants or other fluids on the coating. This can cause the coating to break down and flake off. If you do get fluids on the coating, wipe it off immediately and reapply as needed.
  • Store your coated BCG in a cool, dry place away from direct sunlight.

Following these simple tips will help you keep your coated BCG in top condition and prevent damage to the finish.
