One of the most important components of any AR-15 is the bolt carrier group (BCG). It’s responsible for feeding, firing, and ejecting each round, so it’s critical to choose the right one for your needs. Two of the most popular types of BCGs are Nickel Boron and standard, but which one is best? In this article, we’ll compare Nickel Boron vs standard BCGs and help you decide which one is right for your AR-15.
What is Nickel Boron?
Nickel Boron (NiB) is a type of plating that is applied to the surface of a BCG. The plating is made up of nickel and boron particles that are electroless deposited onto the surface of the carrier. NiB plating provides several advantages over standard BCGs, including increased lubricity, corrosion resistance, and durability.
What is a Standard BCG?
A standard BCG is typically made of steel and is not plated. It’s a reliable option that has been used in AR-15s for decades. However, it lacks the advantages of NiB plating and may require more maintenance and lubrication.
Advantages of Nickel Boron
NiB plating offers several advantages over standard BCGs. The increased lubricity of NiB makes it smoother and easier to operate, which can improve accuracy and reduce wear and tear on the firearm. NiB is also more resistant to corrosion, which makes it ideal for use in humid or wet environments. Additionally, the durability of NiB plating means that it can last longer than a standard BCG, which can save you money in the long run.
Advantages of a Standard BCG
While a standard BCG lacks the advantages of NiB plating, it’s still a reliable and cost-effective option. A standard BCG is less expensive than a NiB-plated BCG, which can be a significant factor for those on a tight budget. Additionally, a standard BCG is less likely to chip or peel, which can be a concern with some types of plating.
Conclusion
When it comes to choosing between Nickel Boron and standard BCGs, there is no clear winner. It ultimately comes down to your individual needs and preferences. If you value increased lubricity, corrosion resistance, and durability, then a NiB-plated BCG may be the way to go. However, if you’re on a tight budget or prefer a more traditional option, then a standard BCG is a reliable choice. Regardless of which option you choose, be sure to perform regular maintenance and lubrication to keep your AR-15 functioning at its best.
