FAQ

What is the BCG?

The BCG is a military-grade weapon accessory that significantly increases the accuracy and lethality of your rifle. It is one of the most popular upgrades among competitive shooters and tactical operators. Installing a BCG is often the first step in building an accurate and reliable AR-15 rifle.

How many types of BCG are?

There are three main types of BCGs on the market: Mil-Spec, Full Auto, and Billet.

  • Mil-Spec BCGs are the most popular type. They are made to government specifications and will work with any AR-15 rifle.
  • Full Auto BCGs are designed for use in full auto rifles. They are not legal for civilian use in the United States.
  • Billet BCGs are made from a single piece of billet aluminum. They are usually more expensive than other types of BCGs but offer superior durability.

Is Nickel Boron BCG better than nitride?

This is a common question that we get asked often. And the answer is not as simple as a yes or no. Both have their pros and cons that make them better or worse for different people. Let’s break it down so you can decide which one is right for you.

  • Nickel Boron BCG: increased durability due to the harder surface, more corrosion resistant than nitride BCGs. Also, shorter cleaning cycles are needed since there is less build-up on the BCG, easier to clean since the nickel boron coating doesn’t allow carbon to adhere to it as easily as nitride does. But more expensive than nitride BCGs and not as widely available as nitride BCGs.
  • Nitride BCG: more affordable than nickel boron BCGs, easier to install since the nitride coating is softer and allows the BCG to slide more easily and more widely available than nickel boron BCGs.

Does the military use Nickel Boron BCG?

Nickel-boron BCGs are becoming increasingly popular in the civilian market, but they’ve been used by the military for quite some time. The U.S. Army’s M16A2 and M4 rifles both use nickel boron BCGs, as do several other militaries around the world. Nickel boron is a super hard surface coating that is applied to the surface of a metal. It has a lot of advantages over traditional finishes like phosphate or anodized coatings. One of the biggest advantages of nickel boron is that it is extremely resistant to corrosion. This makes it ideal for use in harsh environments like salt water or sand where other finishes would quickly degrade.

How to clean BCG?

Cleaning a BCG is not difficult, but it does require some basic knowledge and understanding of the process. BCGs can be cleaned with some different methods, but the most common and effective method is to use a solvent-based cleaner. Several different solvents can be used for this purpose, but the most common and effective solvents are acetone and denatured alcohol. To clean a BCG with a solvent-based cleaner, all you need to do is soak the BCG in the cleaning solution for a while (usually around 30 minutes), and then rinse it off with water. Once the BCG is clean, it is important to lubricate it to prevent corrosion and wear.

How often should BCG be cleaned?

There is no definitive answer to this question, as it depends on several factors, such as how often the BCG is used, what type of environment it is used in, and how well it is maintained. However, as a general rule of thumb, it is generally recommended that a BCG be cleaned every few months.

 

Conclusion

BCG is a great choice for anyone looking for an affordable and quality weapon accessory. BCGs have different types and coating and can be used for a variety of purposes, including self-defense, hunting, and target shooting. We have found and introduced to you a list of the best BCG to help make your purchase decision easier and hope that this information will help you. Thanks for reading!
